5      ==============================      ==============================
6    
7    o gad_som : allow to switch to SOM advection for T & S without corresponding
8      pickup files (using new S/R: MDS_CHECK4FILE).
9    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
10      (for useSingleCpuIO to work in multi-threaded)
11    o pkg/shelfice:
12     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
13       with SHELFICEtopoFile in data.shelfice
14     - move code for reading ice shelf topography and modifying hFacC into separate
15       subroutines of the shelfice package
16     - separate initialisation of "fixed" and "variable" variables
17     - kTopC is not (yet) replaced by kSurfC, although this is possible
18    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
19    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
20      and rename:
21      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
22      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
23    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
24    
25    checkpoint61c
26    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
27      to add mass source/sink of fluid in the interior (3-D generalisation
28      of oceanic real-fresh water flux).
29    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
30    o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)
31    o new pkg: down_slope
32      density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
33      - presently, modify T & S inland (dwnslp_calc_rho.F).
34        can be avoided if rho was stored in common bloc and used in calc_phi_hyd.
35      - implementation for ocean in P-coords not tested.
36      - add secondary test to global_ocean.90x40x15 (input.dwnslp) to check this pkg.
37    o move kSurfC,kSurfW & kSurfS from SURFACE.h to GRID.h (next to kLowC)
38      (to facilitate conversion of oceanic pkg to p-coordinate).
39    o change FIND_RHO to FIND_RHO_2D :
40      pass arguments tFld & sFld as local (tile) 2D-arrays ; +fix EOS_CHECK.
41    o new pkg: cheapaml
42    
43    checkpoint61b
44    o exch2:
45      change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS)
46      - no longer depend on the order sequence (N,S,E,W).
47      - 3rd exchange no longer needed (tested with 24 tiles).
48      - same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff)
49      - exch_UV_A-grid readily available (but not yet tested).
50      comment out 3rd exch call and remove copy of V to U at SE & NE face-corners
51      (both are no longer needed) in exch_uv: no effect in forward run; but
52       get truncation error differences with adjoint exch.
53    o exch2:
54     - change index-bounds storage (moved from target to local tile,
55       more intuitive this way) ; rename/remove some variables.
56     - change utils/exch2/matlab-topology-generator & code_mods accordingly.
57    
58    checkpoint61a
59    o exch2/matlab-topology-generator:
60      fix bug in index bounds for N-S internal exchange (hard to tell if this
61      had any effect on the solution).
62    o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf
63      is exceeded
64    o testreport: modify syntax of awk, so that it works also with
65      awk, and not only with nawk and gawk
66    
67    checkpoint61
68    o autodiff
69      Change default for TAF usage by removing argument '-nonew_arg'
70      This changes TAF subroutine argument list (ordering of active var.)
71      Omission of this flag leads to incompatibility w.r.t. TAMC
72      To restore TAMC-compatibility, need following modifs:
73      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
74      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
75      Tested TAF version is 1.9.22
76      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
77    
78    checkpoint60
79    --->>> This is the last checkpoint for which generating the adjoint
80    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
81    --->>> by default.
82    --->>> Future checkpoints will ommit this flag by default.
83    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
84    o pkg/grdchk: Add gradient check to etan0 perturbations.
85    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
86    o pkg/autodiff: more flexibility in zeroadj.
87      model/src: modifying do_oceanic_phys.F accordingly.
88    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
89    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
90      special setup of gmredi for which the adjoint is stable
91      enough for parameter optimization.
92    o bridging the gap between eddy stress and GM.
93      -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
94          along with a change in CPP option (now ALLOW_EDDYPSI).
95      -> when using GM w/ GM_AdvForm:
96          The total eddy streamfunction (Psi = eddyPsi + K x Slope)
97          is applied either in the tracer Eq. or in momentum Eq.
98          depending on data.gmredi (intro. GM_InMomAsStress).
99      -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
100      The key modifications are in model/src/taueddy_external_forcing.F
101      pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F
102    
103    checkpoint59r
104    o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array
105      from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
106      fix option to read coriolis(@ cell-corner) from files with CS-grid.
107    o pkg/mnc: add some attributes to standard 1D-coordinate variables
108    o pkg/diagnostics: enforce missing_value attribute for scalar variables at
109      mass points, when using mnc for output
110      - add runtime parameter (missing_value, missing_value_int) to override
111        default (which is the value of getcon('UNDEF'))
112    o pkg/mnc: prepare mnc for the actual use of missing values with the
113      diagnostics package: small fix in mnc_cw_readwrite.template and more
114      initialisation of never used fields
115      - replace mnc_common.h and mnc_id_header.h with corresponding upper case
116      versions
117    o pkg/thsice/thsice_ini_vars.F added default initial values so that
118      thermodynamics sea ice solver does not blow up when some initial fields
119      are missing.
120    o move from external_forcing_surf.F to ini_forcing.F
121      the p-coord. hack consisting in using pLoad to set phi0surf ;
122      update output of tutorial_global_oce_in_p (affected @ truncation level).
123    o Freshen up a bit hs94.1x64x5, notably:
124      remove rotationPeriod and tRef=5*0. (adjoint only), and add
125      exactConserv=.TRUE.
126    o pkg/generic_advdiff:
127      change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only
128      applies to files where Temperature & Salinity 2nd Order moments are used.
129    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
130      this uses a dynamically allocated internal state data structure
131      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
132      and requires a fortran 90 compiler
133    
134    checkpoint59q
135    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
136       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
137    o Refresh tutorial_global_oce_biogeo, notably:
138      - change bathymetry (put back seamounts in ACC, use hFacs)
139      - change EOS (POLY3 --> JMD95Z)
140      - use Bryan-Lewis vertical diffusivity
141      - use multidimensional advection
142      - remove old virtual virtual in dic pkg, now done through ptracer pkg
143      - change a couple of parameters in dic pkg
144    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
145    o pkg/obcs: change default to OBCSfixTopo = .true.,
146      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
147      - replace "debugMode" with "debugLevel .GE. debLevB"
148    o implementation of TAF directives for gchem,cfc,dic
149    o remove "exp5" (replaced by tutorial_deep_convection).
150    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
151      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
152      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
153      --> changes results in exp4, seaice_obcs
154    o tutorial_deep_convection :
155      update the set-up and increase resolution and domain size ; start
156      from pseudo initial conditions = output at t=120mn in order to see
157      something happening when running testreport.
158    o pkg/seaice: add os7mp as an advection scheme
159                  add check for advection schemes
160                  add a flag for restoring T and S underneath sea ice
161    o pkg/my82: add netcdf-support and diagnostics
162    o thsice pkg:
163      - Now hsMax limits snow height by turning it into ice following
164        flooding scheme (and now conserving energy)
165      - Slight rewriting of the formula in thsice_calc_thick.F
166      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
167      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
168    
169    checkpoint59p
170    o gchem / dic / cfc :
171      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
172      - add new parameter files: "data.dic" & "data.cfc" ;
173      - various re-arrangement in initialisation & header file ;
174      - fix tutorial_global_oce_biogeo for multi-threaded test.
175    o pkg/dic: test for "pickup_dic" file when restarting ;
176      if no pickup-file, can restart with a re-initialised pH (same as it did
177      before) providing pickupStrictlyMatch is set to False.
178    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
179      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
180    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
181      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
182    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
183     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
184       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
185    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
186       scheme to use for vorticty-term ;
187     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
188       (with default selectVortScheme, return to original discretisation)
189     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
190    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
191    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
192      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
193      also fix diagnostics VISCAHW & VISCA4W.
194    
195    checkpoint59o
196    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
197    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
198      move a few statemens out the main loop into separate loops
199    o pkg/shelfice:
200      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
201        (kg/m^2/s), does not break tests, because in verification/isomip,
202        rhoConstFresh=rhoConst (by accident)
203      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
204      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
205        new file model/src/seawater.F, so that they are available for all pkgs.
206      - convert potential temperature into in-situ temperature. This changes the
207        isomip tests => update tests
208    o add a flag writePickupAtEnd (default=true) to be able to suppress
209      writing a pickup at the last timestep
210    o tools/mpack-1.6 :
211      - disable automake (not working) and autoconf (not needed).
212      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
213        also cleaner with much less compilation warnings.
214    o pkg/profiles:
215      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
216      (for "less than 32 characters name" compiler requirement)
217    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
218      conditions that have a different sampling frequency than S/T/U/V obcs
219    o pkg/diagnostics (stats-diags):
220      - fix global Min/Max in case 1 processor get only empty tiles
221    o genmake2: replace (4 times)
222         make genmake_tc_1.o >> genmake_warnings 2>&1
223      with
224         COMM="$CC $CFLAGS -c genmake_tc_1.c"
225         echo $COMM >> genmake_warnings
226         $COMM >> genmake_warnings 2>&1
227      to make genmake2 always see the value of CC as specified in the optfile.
228    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
229      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
230      - modify verification advect_cs test to test SOM-advection on CS-grid.
231    o pkg/ctrl:
232      - Rewrite of ctrl_map_ini_ecco.F,
233        introducing a generic routine (ctrl_map_ini_gen.F).
234      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
235    
236    checkpoint59n
237    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
238      number in dedicate array "hdiag":
239      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
240        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
241      - many small changes (integer format) for large number of diagnostics
242      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
243        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
244    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
245      usingSphericalGrid, this allows to define the rotated grid coordinates
246      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
247      geographical coordinates according to the inverse of the rotation defined
248      by the Euler angles, so that Coriolis parameter and online-interpolation by
249      exf works with the geographical coordinates on XC/YC/XG/YG.
250      Naturally, this feature does not work with all packages, so some
251      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
252      profiles), because there the coordinates are assumed to be regular
253      spherical grid coordinates.
254    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
255      - introduce isopycnal diffusion coefficient control.
256    o tools/adjoint_options:
257      - additional control vector components.
258    o pkg/mnc: have mnc create marginally meaning full coordinate variables
259      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
260    o pkg/mypackage:
261      - add example of read/write pickup for state-var ;
262      - add entry points to the main code for state-vars diags & write-pickup.
263    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
264      transitions for useExfYearlyFields
265      - add new subroutine that determines the file to read from for
266        use*YearlyFields = .TRUE. and .FALSE.
267      - add a verification experiment to global_with_exf that tests
268        useExfYearlyFields with USE_EXF_INTERPOLATION defined
269    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
270      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
271      subroutines (which could be generated from a template, because they are
272      almost identical), for now they are included in obcs_prescribe_read.F for
273      simplicity
274    o pkg/exf:
275      - add a little more diagnostic to exf_interp_read (in analogy to
276        mds_read_field, can be turned off with debugLevel < debugLevA=1)
277      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
278        ugly but fast by unrolling short inner loops, inserting a unroll=8
279        directive in routine lagran, and splitting a loop and making do while the
280        outermost loop (the latter requires the intoduction of index arrays)
281    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
282    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
283      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
284    o verification/seaice_obcs: updated for restart test and latest options
285    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
286      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
287      for now this is only available for the C-grid code and also within
288      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
289    
290    checkpoint59m
291    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
292      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
293    o gad_som : fix flux output (& diagnostics) to have same units as other  
294      advection scheme fluxes (was previously multiplied by deltaT).  
295    o added verification/seaice_obcs both to test seaice open boundaries
296      and to provide an example matlab scrpt for generating them
297    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
298    o pkg/salt_plume: clean up salt_plume_frac.F to
299      remove redundancy in PlumeMethod 1 and 4
300    o pkg/kpp: added saltplume diagnostics
301    o pkg/obcs and pkg/seaice:
302      - do not set uice and vice to zero when OB*icefile are unspecified
303      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
304      - moved seaice tracer obcs after call to seaice_growth
305    o pkg/salt_plume: added various options for salt plume depth
306      criterion and for vertical distribution of the salt
307    
308    checkpoint59l
309    o pkg/ptracers: new version of ptracers pickup:
310      read meta file and write only fields which are needed to restart.
311      ( same logic as main pickup file ; also using pickupStrictlyMatch )
312    o pkg/seaice:
313      - add timescale for melting due to warm mixed layer as a means of
314        setting SEAICE_availHeatFrac more conveniently
315      - add a CPP-flag/runtime parameter check for flooding algorithm
316      - reformulated availHeat in seaice_growth.F to be independent of AREA
317    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
318      unit changes
319    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
320    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
321      SX vector computer.
322    o pkg/seaice:
323      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
324        seaice forcing fields can now be read only through pkg/exf
325      - removed some unused halos
326    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
327    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
328      or U/VICE from U/VWIND before computing U/VSTRESS
329    
330    checkpoint59k
331    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
332      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
333    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
334      all experiments pass when compile with un-initialised var. checking option.
335    o added pkg/salt_plume
336    o script to test restart (for now, in MITgcm_contrib/jmc_script)
337    o pkg/seaice: new read/write pickup version.
338      read meta file and write only fields which are needed to restart.
339      ( same logic as main pickup file ; also using pickupStrictlyMatch )
340    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
341    o lab_sea.hb87: modify the domain & update output.hb87.txt :
342      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
343      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
344      process. Fixed here by closing the domain at the Northern boundary.
345    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
346    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
347      a set of consecutive levels in/from a 3-D array.
348    o pkg/ptracers:
349      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
350      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
351    
352    checkpoint59j
353    o in pkgs: dic, obcs, offline, rbcs:
354      standard way to compute coeff. for time interpolation between 2 time reccords
355      which retains full precision (& make results less dependent on compiler).
356      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
357    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
358      packages instead of reading ice cover and wind speed separately
359    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
360     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
361      to allow to compile customized code before the update)
362    o cleaning-up:
363      - fix CPP instruction syntax in pkg/obcs
364      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
365        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
366      - fix some threads issue in IO parts.
367    o pkg/dic:
368      - add tons of "_d 0" (--> much better testreports !)
369       and then update outputs of tutorial_global_oce_biogeo
370    o pkg/mom_fluxform:
371      add a special version of momentum advection intended to conserve momentum
372      next to a bathymetry step or a coastline edge. (default = off = #undef)
373    o new read/write pickup version:
374      - for now, only implemented for main (mdsio) pickup file.
375      - write out only what is needed to restart; merge pickup_nh , pickup_ph
376        and main pickup together.
377      - read meta file; read only what is needed to restart; stop if a field
378        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
379        if it make sense (even if the restart is not perfect).
380      - if no meta file, assume that pickup to read corresponds exactly to
381        a pickup that would currently be written.
382      - read pickup written in the old format (until checkpoint59i) if it
383        recognizes an old meta file (no field-list).
384      - add a meta file in exp. which starts from a pickup: 2 cases:
385        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
386         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
387        b) a meta file describing the content of the associated pickup file
388         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
389    o pkg/mdsio & pkg/rw:
390      - new routine to read a meta file ; new set of routine to read
391        Multiple-fields file (with meta file).
392    o added open boundary conditions capability for seaice
393        HSNOW, HSALT, UICE, and VICE
394    
395    checkpoint59i
396    o adjoint:
397      * fix multiDimAdvection adjoint
398        (partial recomputation problem by TAF for fVerT(:,:,kDown)
399        and comlev1 size definition (maxpass vs. max. number of tracers)
400      * verification/global_ocean.90x45x15 adjoint now tests
401        NLFS and multiDimAdvection using DST3 (=30)
402      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
403    o pkg/kpp: add "_d 0" to real constant (if missing);
404      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
405      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
406    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
407      for internal parameters related to restart process (formerly from PARAMS.h)
408      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
409    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
410      as argument. (only atm2d & obcs write_pickup have not yet been updated)
411    o pkg/monitor:
412      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
413      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
414      - account for deep Atmosphere factor and density factor (anelastic)
415    o added open boundary conditions capability for seaice HEFF and AREA
416    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
417      thermodynamics
418      - requires a little reorganization, which affects the testreport results
419        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
420        so that now the conservative form is tested
421      - add a few comments
422    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
423    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
424    o add new diagnostics to seaice: advective, diffusive fluxes (only for
425      multidim-advection, for scheme 2 they are not filled) and transports,
426      thermodynamic growth rates
427    o change units of EmPmR (inside the code, + within coupling interface)
428      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
429      Affects results @ truncation level (cg2d match) and update output of
430       experiments: lab_sea(6), global_ocean.90x40x15(10),
431      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
432      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
433      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
434      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
435    
436    checkpoint59h
437    o pkg/exf:
438      - improve vectorization by moving if-statement out of loops in
439        exf_mapfields, exf_radiation
440      - exf_bulkformulae.F: introduce 2D fields and vectorize code
441    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
442    o testreport:
443      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
444        monitor & update offline_exf_seaice exp. output.
445      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
446    o pkg/seaice:
447      - bug fix in the evp solver: boundary conditions were affected be
448        masking of zMax/zMin (changes results)
449      - minor bug fix in boundary conditions in seaice_calc_strainrates
450        (changes results for no_slip)
451      - seaice_lsr.F: make interpolation of eta dependent on boundaries
452      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
453      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
454        stress formulation and no-slip boundary conditions
455    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
456      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
457    o pkg/seaice: a first HSALT time stepping equation has been checked in
458    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
459      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
460      without requiring DO-IF statements
461    o pkg/thsice:
462      use continuous power-law function for partition of energy between lateral
463      melting/freezing and thinning/thickening ; old code using step function
464      still available with #undef THSICE_FRACEN_POWERLAW
465      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
466    o testreport: change AD testing : check against results/output_adm.txt
467      using same scripts as for forward test.
468    
469    checkpoint59g
470    o adjoint testing: in preparation for changing testreport:
471      - output format: cost and grad written on separated lines
472      - ad output results in directory "results" (instead of "results_ad")
473    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
474    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
475    o pkg/ecco: allow user defined cost function contributions
476    o testreport:
477      Allow to choose (per experiment) the list of tested output variables
478       and the main variable (used to issue a pass/FAIL ) ;
479      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
480      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
481      Also modify printing of summary:
482       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
483       b) echo the list of tested variables in the individual summary.txt of
484          each experiment.
485    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
486      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
487      (but still depend on the tile decompostion of the domain).
488    o pkg/seaice: change a discretization detail to make the B-grid code
489      "more symmetric". This change is likely to remove all "ridges/leads" that
490      where quasi-aligned with the grid in B-grid solutions. It may also be
491      the solution to the stress coupling issues with the B-grid.
492    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
493      remove .cvsignore from input dir. (since testreport no longer run here).
494    o pkg/thsice:
495     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
496     - fix reshaping of sea-ice just after advection:
497       melt all the ice only if ice-volume is too small.
498     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
499       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
500     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
501    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
502      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
503    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
504      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
505      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
506      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
507      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
508      -> update output.txt
509    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
510     this affects truncation error: -> update output.txt of exp:
511      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
512      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
513    
514    checkpoint59f
515    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
516    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
517      a bounded range (in forward mode)
518    o pkg/ecco, ctrl, autodiff and mom_common:
519     internal parameter controls, completements of implementations
520    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
521    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
522      (not seem any difference in testing results).
523    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
524       at face corners.
525    o pkg/generic_advdiff:
526     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
527      loop range indices for computing vertical advection tendency
528      and do the calculation in the interior only (no overlap) ;
529      for now, only implemented for SOM advection (to save CPU time).
530     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
531    o exch2 adjoint
532      First set of changes:
533      - add exch2 hand-written adjoint templates
534      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
535        This will require cleanup in pkg/autodiff/*.F
536        (changed routines currently kept separate in verif. code/)
537      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
538        that used to hide exch2 or cubed-sphere specific code
539        (commented via 'cph-exch2')
540    o pkg/seaice
541      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
542    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
543       output of global_ocean.cs32x15.thsice .
544    
545    checkpoint59e
546    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
547      for B-grid vector (not yet tested) and C-grid vector (<- only used
548      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
549    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
550      (#ifdef ALLOW_SALT_PLUME)
551    o gather_2d/scatter_2d: removed halo regions
552    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
553      scheme and the corresponding test case (under front_relax dir). For now,
554      only available with Skew-flux form and not yet tested in realistic set-up.
555      adjoint: store directives updated, but gradient checks deteriorated,
556      so maybe GM/Redi adjoint is now broken.
557    o seaice adjoint
558      * add AREA, HEFF, HSNOW as control variable
559        (should not change lab_sea results)
560      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
561    o pkg/seaice:
562      * added computation of saltFlux in seaice_growth;
563        For time being, sea ice salinity is assumed constant
564        contribution of snow flooding to freshening of sea ice is neglected.
565        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
566        defaults to 0.0 in order to maintain backward compatibility.
567        Typical values for SEAICE_salinity are 4 to 10 g/kg.
568      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
569      * added SEAICE_availHeatFrac, which specifies fraction of surface level
570        heat content used to melt or grow ice
571      * commented out cap of HICE: it helps keep ice thinner
572      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
573      * applied OBCS T/S mask to HEFFM sea ice mask
574    
575    checkpoint59d
576    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
577     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
578     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
579    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
580     and change default value of parameter "GM_Small_Number";
581     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
582       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
583       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
584    o pkg/ecco: cost function when applying pkg/smooth to controls
585    o pkg/ctrl: add forcingPrecond run time parameter
586    o pkg/seaice:
587     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
588     - fix bug in metric terms of u-equation in LSR solver (implicit part),
589       changes verification/lab_sea
590     - rearrange implicit part of u-equation in LSR solver to make it easier to
591       read, understand, and debug. This causes changes at the truncation level.
592     - fix (serious) bug in the boundary conditions (sign error in the implicit
593       part) of the LSR solver. Changes all LSR results.
594     - fixed problem with HSNOW initialization to avoid thick snow when AREA
595       is initilized with small values - does not change lab_sea results.
596     - added HsnowFile initialization capability
597    o pkg/smooth: addition to model/src and pkg/ctrl so allow
598     initialization of pkg/smooth and application to control vector
599    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
600    o dependencies: pkg/profiles requires pkg/cal
601    o pkg/profiles:
602     - added option ALLOW_PROFILES_GENERICGRID
603         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
604         that interpolation information (grid points and coefficients) is provided
605         within the netcdf input files.
606         -> sample matlab scripts can be found in MITgcm_contrib/gael
607         that allow you to prepare netcdf input files.
608     - also modified: cleaner include statements, cleaner error print statements,
609       cleaner stops when error, and more tests of the netcdf input files consistency.
610    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
611    o pkg/seaice:
612     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
613       requires a new routine: seaice_diagnostics_fill.F
614     - make sure that seaice does not move if not forced (pressure replacement
615       method, Hibler and Ip, 1995), changes results
616     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
617     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
618       It is turned off by default (=-1.), because it changes the results.
619     - make it possible to read AREA from a file, too.
620    
621    checkpoint59c
622    o add S/R and diagnostics for oceanic mixed-layer depth
623    o move GMRedi call after all vertical mixing schemes (including KPP)
624    o pkg/thsice:
625     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
626      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
627    o pkg/obcs:
628     - bug fix for balance code
629    o pkg/seaice:
630      - allow values of SEAICE_elasticParm > 1
631      - add new parameter SEAICE_evpTauRelax as an alternative
632        to SEAICE_elasticParm
633      - make lsr boundary conditions free slip (by default), changes result
634      - add code for no slip boundary conditions for lsr
635      - set minimum of zeta to zero (and not 4e8) (changes results)
636      - add a cap on AREA after advecting AREA if seaice_growth is not called
637    o change calculation of Visbeck K:
638      - no longer depend on tapering scheme; instead, compute slope (limited
639        by GM_maxSlope). this is equivalent to what was comuted before with
640        clipping or linear tappering.
641      - fix vertical averaging (wrong by 1/2 level)
642      - leave the old version (but will not be maintained) within
643        #ifdef OLD_VISBECK_CALC / #endif
644      - update output of exp. ideal_2D_oce
645    o change error catch in calc_r_star to improve vectorization
646    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
647      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
648    o adjoint:
649      Re-organized adjoint checkpointing according to Matt Mazloff
650      (but with modifs/completions/cleanups)
651      Storing is now bundled into large arrays to optimized I/O
652      (and second step in cleanup of the_main_loop)
653    
654    checkpoint59b
655    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
656      - export/import (between ocean & coupler) fields needed for ocean DIC.
657    o pkg/seaice:
658      - get rid of three more exchanges seaice_calc_viscosities (required
659        different loop boundaries in seaice_lsr and seaice_ocean_stress)
660      - bug fix in seaice_ocean_stress (update of lab_sea required)
661      - reduce loop boundaries to necessary minimum also in seaice_evp
662      - go back to the old way of computing deltaC/Z as the adjoint likes that
663        better
664    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
665      passive tracer to an Age Tracer) + update output.txt
666    o pkg/exf:
667      - implement A-grid / C-grid selection for wind-stress input files.
668      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
669      for now, in exf_bulk_largeyeager04.F only :
670      - change implementation for case where windspeed + 2. components wind-stress
671        are read-in. AND use rhoConstFresh to convert evap.
672    o pkg/seaice:
673      - use correct EXCH_UV for wind-forcing (on A-grid).
674      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
675        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
676    o pkg/exf:
677      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
678      EXF_INTERPOLATION:
679      - merge global_with_exf/code version of exf_interp_read.F
680        to the main code ;
681      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
682        reading the file ; Important: This options needs to be defined to recover
683        previous code.
684        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
685      - no longer loose real*8 precision along the way when using exf_iprec=64.
686    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
687      - change discretisation of evp-solver in order to avoid another exchange
688        (changes lab_sea) and clean up a little
689      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
690        help the adjoint (this also changes the results slightly)
691      - add a few "_d 0" where they had been missing in seaice_evp.F
692      - cleaning up: remove unused seaice_calc_rhs.F
693    o pkg/exf: some cleaning-up:
694      - change various "constants" into runtime parameters
695      - cleaned-up Large&Yeager04 routine which should eventually
696        replace exf_bulkformulae.F (changed names of S/R and CPP)
697        and merged various ALLOW_ATM_WIND options
698     only used with thsice pkg (in thsice_get_exf.F):
699      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
700        which are used when useStabilityFct_overIce=TRUE (= the default)
701      - change default values of ice & snow emissivity and scale downward LW
702        by ice & snow emissivity.
703    o pkg/thsice:
704     fix few little problems, in thsice_calc_thickn.F:
705      - growth vertically (and not laterally) if iceFrac == iceMaskMax
706      - melt only laterally if hIce < hThinIce (as the comments say)
707      and in thsice_extend.F:
708      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
709      - start to form ice as soon as the minimum ice-volume is reachable.
710     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
711      and cpl_aim+ocn
712    o pkg/kpp
713     - move computation of surface related input fields to KPP into a new
714       subroutine kpp_forcing_surf.F
715     - remove wrong (within bi,bj loops) EXCH calls.
716     - little cleaning (add argument myThid in last position, cvs header ...)
717     - for now, fix conservation problem by exchanging KPPviscAz (may not
718       be the best fix)
719    o pkg/seaice
720     - check for inconsistent evp parameter/cpp-flag combination
721     - remove leftover errIO flat for obsolete name list error handling
722    o OpenAD
723     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
724    
725    checkpoint59a
726    o pkg/seaice: some parameter clarifications and a little bit of clean up
727    o pkg/thsice: rename run-time parameters:
728       himin       -> hIceMin
729       himin0      -> hThinIce
730       hihig       -> hThickIce
731       i0          -> i0swFrac
732       transCoef   -> bMeltCoef
733       frac_energy -> fracMelting
734      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
735       with default values (for now) that do not change the results.
736      remove old version of thsice vars advection in pkg/seaice.
737    o in FFIELDS.h:
738      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
739      - make pLoad & sIceLoad always available (but still only used if
740         ATMOSPHERIC_LOADING is #define).
741    o pkg/kpp: replaced _KPP_RL with _RL
742    o bug fixes for vertical diffusivity computations when both KPP and
743        3D diffusivity arrays are used; pkg/kpp/kpp_calc_diff_s & _t.F
744        are no longer updating the vertical diffusivity array
745        (passed as argument) but are (re-) setting those arrays.
746    o pkg/seaice: fix bug in evp solver, while doing that
747      - change (improve?) discretization of stress computations for both
748        cgrid-lsr and evp solver
749      - add a new routine to compute strain rates
750      - the above changes lab_sea results
751      - add no slip conditions for evp solver (off by default), lsr-version
752        may follow
753      - fix exchange for shear at Z-points (does not change lab_sea)
754      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
755        (to force the user to pick a time step since there is not "safe" way
756        of choosing it)
757      - add principal stress diagnostics
758      - rearrange fields for evp a little to avoid having to call a: too many
759        exchanges and b: exchanges for stress trensor components which we do
760        not have.
761      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
762        of evp, complete rewrite for lsr case (latter is does not yet work
763        in all cases)
764    o pkg/kpp: add code to have mixing in shelf ice caverns
765      - add myThid to all kpp routines (long overdue)
766    
767    checkpoint59
768    o pkg/exf:
769      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
770        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
771      - move exf header files from lower_case.h to UPPER_CASE.h ;
772        add missing cvs Header & Name
773      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
774      - add namelist param. selectStressGridPosition, exf_monFreq
775      - retire many _CLIM routines, and remove data.exf_clim
776        + params moved to data.exf
777        + climsst, climsss now handled by exf_set_gen, i.e.
778          climss?period=0 refers to constant field,
779          climss?period=-12 to monthly forcing
780      - split up namelists in data.exf
781    o pkg/seaice:
782      - remove seaice_exch and seaice_exch_uv
783      - remove superfluous exchange of theta
784      - add myThid to seaice_budget_ocean/ice
785      - add new interface for atmospheric wind forcing (C-grid only)
786        + new routine
787        + two new field (taux, tauy for stress over ice)
788        + removed one global field (DAIRN) for C-grid case only
789    o pkg/thsise
790      - 2nd set of modifs for thsice adjoint in conjunction with exf
791    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
792    
793    checkpoint58y_post
794    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
795      vertical diffusivity, similar to that in MOM4; turned on using
796      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
797      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
798    o Added capability for 3D specification of background vertical diffusion
799      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
800      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
801      "data" file that contains the 3D vertical diffusivity coefficients.
802    o ice dynamics (pkg/seaice) with thsice thermodynamics:
803      - add code within pkg thsice to advect & diffuse sea-ice fields
804      similar to (and will replace) what has been added in  seaice_advdiff.F,
805      but: - conserving Mass, Heat & Salt.
806           - better when using non-linear advection scheme (not yet fully tested)
807           - can also be used in atmospheric set-up (for now, only the diffusion).
808    
809    checkpoint58x_post
810    o IO option for global-file compact format:
811      - add options when generating topology (utils/exch2/matlab-topology-generator)
812      - add I/O capability (pkg/mdsio).
813      - adapt utils/matlab/rdmds.m to read this format.
814      for now long-line format not yet supported by pkg/mdsio (& exch2).
815    o shelfice: add a few diagnostics
816    
817    checkpoint58w_post
818    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
819      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
820      (and replace horiVertRatio in NH code).
821      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
822                         and tutorial_plume_on_slope (sensitive to truncation)
823    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
824      directly to drive seaice model (C-grid only)
825    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
826     - reintroduce computation of wind from stress,
827     - compute tau (in exf_bulkformulae.F) from windstress averaged to
828       mass points to avoid tau = 0
829     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
830    o rdmnc.m: make it work with "global" files created with gluemnc
831    o rdmnc.m : some improvements in dealing with singleton dimension
832      (tested on all testreport mnc output files).
833    o genmake2: disable pkg/profiles if netcdf test fails.
834    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
835    o move call to cal_readparms up to make calendar parameters/variable available
836      to all packages
837    
838    checkpoint58v_post
839    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
840      useDynP_inEos_Zc tested.
841    o pkg/exf: changes to properly interpolate/mask/scale initial fields
842    o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
843      and portions thereof.  See read_cs.txt for description and examples.
844    o utils/matlab/cs_grid/bk_line: to compute transport through passages,
845      add a script (grt_circ_bkl.m) to generate broken-line between 2 points,
846      following the great-circle arc between those 2 points.
847    o trap un-initialized variable with pathscale compiler on weddell.mit.edu
848      (thanks to Constantinos): fix few problems and get (almost) all exp to pass.
849    o 2nd-Order Moment Advection Scheme (Prather, 1986): first check-in
850     - enable by setting #define GAD_ALLOW_SOM_ADVECT (in GAD_OPTIONS.h)
851     - used without limiter (AdvScheme=80) or with Prather limiter (AdvScheme=81)
852     - still needs work (not working with some options ; efficiency to improve)
853       and serious testing.
854     - use this scheme for temperature & salinity in 2 advection test exp.:
855       advect_xy & advect_xz, respectively.
856    
857    checkpoint58u_post
858    o new test-exp: fizhi-cs-32x32x40 (40 levels) to replace the 10 levels.
859    o move call to INI_FORCING from PACKAGES_INIT_VARIABLES to INITIALISE_VARIA.
860    o testreport: add option "-skipdir" to skip some test.
861    o exf: when input wind-stress (#undef ALLOW_ATM_WIND), by-pass turbulent
862      momentum calculation.
863    o gad_advection: fix vertAdvecScheme (if different from advectionScheme)
864    o some cleaning: usePickupBeforeC35 no longer supported ; remove this option.
865      remove checkpoint.F and the_correction_step.F (no longer used);
866      do the k loop inside CYCLE_TRACER (supposed to be more efficient).
867    o add option (linFSConserveTr) to correct for tracer source/sink due to
868      Linear Free surface
869    o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine
870    o pkg/thsice: fix reading mnc-pickups
871    
872    checkpoint58t_post
873    o pkg/diagnostics: fix multi-threaded output (when singleCpuIO=F)
874    o pkg/mdsio:
875     - clean-up mdsio_readfield.F & mdsio_writefield_new.F and
876       move to new files: mdsio_read_field.F (S/R MDS_READ_FIELD) &
877       mdsio_write_field.F (S/R MDS_WRITE_FIELD);
878     - fix multi-threaded singleCpuIO option in MDS_WRITE_FIELD
879     - collect old S/R  in one file: mdsio_rw_field.F (now just a call to
880       either MDS_READ_FIELD or MDS_WRITE_FIELD )
881     - new S/R (to replace MDSWRITEMETA), which allows to write more
882       informations (variable names, time ...) to meta files.
883     - modify rdmds.m to give back the meta file content.
884    o pkg/diagnostics: change vertical interpolation to be safer, and more
885       flexible (define p-levels to interpolate to in data.diagnostics);
886      add argument to S/R DIAGNOSTICS_GET_POINTERS to catch the right
887       diagnostic pointer.
888    o pkg/seaice: more cleaning up of seaice_growth, added many comments
889    o pkg/exf: put runoff0 and runoff1 into the appropriate common block
890    o fix multi-category seaice:
891     - change cpp flag SEAICE_MULTILEVEL to more meaningful name:
892       SEAICE_MULTICATEGORY
893     - fix short wave heat flux
894    o pkg/seaice: change default (SEAICE_OPTIONS.h): use C-grid dynamics
895       and allow to use EVP solver. Change forward lab_sea: test both EVP
896       solver and LSR solver, and use C-grid dynamics (like lab_sea adjoint)
897    o Initial check-in of lab_sea adjoint
898      (very similar to natl_box_adjoint/code_seaice)
899      * used C-grid and EVP solver
900      * used KPP, GM/Redi
901      * uses inAdExact=.TRUE.
902      * gradient checks fail for both ADM and TLM
903        due to sensitive snow melt code in seaice_grwoth (look for "JZ")
904        f.d. gradients actually seem more problematic than ADM, TLM gradients;
905        issue is related to forward mismatch between g77 an ifort
906    o pkg/seaice: overhaul of thermodynamics
907     - growth.F and groatb.F are replaced by new routine seaice_growth.F
908     - budget.F is replaced by two new routines seaice_budget_ocean/ice.F
909     - move a few global fields out of SEAICE.h into seaice_growth.F and
910       make them 2D (FICE/QNETO/ ...)
911     - remove FO (it is the same as QNETO)
912     - introduce a few local fields to avoid modifying external fields such
913       as atemp, etc.
914    
915    checkpoint58s_post
916    o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F
917      changed exf_set_gen.F so that
918        genperiod=0 means input file is one time-constant field and
919        genperiod=-12 means input file contains 12 monthly means
920    o CG2D: use pre-computed solver main-diagonal (stored in common block);
921      this affects truncation error ; generate new output file for exp. which
922      fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d),
923        global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d),
924        ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d),
925        MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d),
926        tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d),
927        vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d)
928    o start implementation of deep-atmosphere and anelastic formulation
929    o verification: remove 2nd copy of input files and use script "prepare_run"
930      to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M)
931    o mom_common/vecinv/fluxform: fix a few initialisation isssues
932    o profiles: fix for multithreaded case
933    
934    o diagnostics: rename few diags:
935      s/'PRESSURE'/'RCENTER '/g
936      s/'TICE    '/'oceFreez'/g
937      s/'TAUX    '/'oceTAUX '/g
938      s/'TAUY    '/'oceTAUY '/g
939      s/'SWFLUX  '/'oceQsw  '/g
940      s/DIFx/DFxE/g
941      s/DIFy/DFyE/g
942      and add few ocean-forcing diagnostics:
943      atmPload, sIceLoad, oceQnet, oceFWflx, oceSflux, surForcT & surForcS
944    o modifications to pkg/seaice/growth.F and budget.F, which change results of
945      lab_sea experiment: HSNOW was sometimes treated as effective and sometimes
946      as actual snow thickness.  It now refers everywhere to effective snow
947      thickness, meaning that for non-zero AREA, actual thickness is HEFF/AREA.
948    
949    checkpoint58r_post
950    o modifications to pkg/seaice/growth.F, which change results of
951      lab_sea experiment: fixes pertain to melting snow over open water, to
952      masking EVAP under sea ice, and to using the correct AREA variable for
953      computations of EVAP, PRECIP, HSNOW, and GHEFF
954    o add ability to read bathy, salt, and theta using MNC (off by def)
955    o add flooding algorithm and advection of HSNOW for pkg/seaice;
956      both are turned off by default and do no change any results
957    o seaice advection with pkg/thsice: a step toward the use of non-linear
958      advection scheme, but #ifdef or commented out for now (requires more EXCH).
959    o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
960      (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
961      in natl_box (affects results @ truncation level: update output.txt)
962    o multi-threading and IO:
963      - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
964      - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
965        (needed to work with SingleCpuIO): tested in all verif. exp.
966    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
967      affects the results (but none of the verification test uses this scheme).
968    o Adding some pkg/diagnostics capability to pkg/seaice
969      (will certainly be subject to changes)
970    o ctrl: adding new control variables:
971      lwflux, lwdown, evap, snowprecip, apressure, runoff
972    
973    checkpoint58q_post
974    o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
975      1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
976      high_res_cube configuration by 4% on Columbia.
977    o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
978      add (in global_with_exf/code) a version of EXF_INTERP_READ without
979      dynamical allocation (seems to work in multi-threaded).
980    o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
981      single CPU io) so that TAF does not have to see EESUPPORT.h
982    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
983    
984    checkpoint58p_post
985    o obcs: stop if obcs is used with useCDscheme = .true.
986    o shelfice:
987     - fix a sign error so that no slip at shelfice interface works
988     - remove stop for combination non-hydrostatic code and shelfice. That does
989       not mean, that the results are correct, but at least they are numerically
990       stable
991    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
992    o added adjoint exch routined for all exch*3d* routines
993      and updated flow directives
994    
995    checkpoint58o_post
996    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
997      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
998    o change controling S/R for writing pickup file (new S/R do_write_pickup)
999      and clean-up reading/writing of pickup files.
1000    o fix local version of read/write pickup (NH part) in rotating_tank/code
1001    o simplify EXCH interface:
1002     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
1003     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
1004    o added the regrid package
1005    o shelfice:
1006     - add a simple boundary layer scheme to reduce noise
1007     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
1008    
1009    checkpoint58n_post
1010    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
1011       local variable (not in common block).
1012    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
1013      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
1014      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
1015        to work with SingleCpuIO.
1016    o add "_d 0" to real constant of pkg/cfc subroutines ;
1017       update exp. cfc_exemple & tutorial_cfc_offline output files.
1018    o multi-threading and IO:
1019      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
1020        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
1021      - barrier before and after reading.
1022      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
1023      - avoid using MDS_WRITELOCAL for LAND pkg output.
1024      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
1025        common-block variables ; Allows multi-threading with master-thread IO.
1026    o change default MAX_NO_THREADS from 32 to 4 ;
1027      and stop cleanly when MAX_NO_THREADS is too small.
1028    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
1029    
1030    checkpoint58m_post
1031    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
1032       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
1033    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
1034       keep global_ocean.90x40x15 (for AD testing) with former secondary test
1035       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
1036    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
1037        add MITgcm_tutorials (= code + all the tutorials)
1038    o ecco, option to compute cost for total ssh (mean+anom)
1039    o consistent with addition of ptracer and ssh in pkg/profiles
1040    o profiles: adding ptracer and ssh
1041    o testreport: change multi-test output-file name
1042      (from output.txt.{name} to output.{name}.txt)
1043    o profiles: now ok for mutli-tiles case
1044    o seaice: add 4 parameters for different advection schemes for area,
1045      (effective) seaice thickness, enthalphy, and snow height. Their default
1046      is the standard parameter SEAICEadvScheme
1047    o calc_gw:
1048     - add cosFacU in zonal viscous flux (harmonic.visc.).
1049     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
1050       of tutorial_plume_on_slope.
1051    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
1052    o calc_gw: true flux-form, account for horizontal grid spacing.
1053      update rotating_tank results, but not plume_on_slope (affected at
1054      truncation level, 11 digits).
1055    
1056    checkpoint58l_post
1057    o calc_gw:
1058     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
1059     - remove side-drag for now (need to fix it); update plume_on_slope results.
1060     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
1061    o commit code to make SST/SSS weights spatially variable
1062      (based on either variable in-situ or variable initial T/S weights)
1063    o pkg/ecco:
1064      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
1065        now based on horizontally varying weights wthetaLev, wsaltLev
1066      * cost_averagesflags now returns year indices in addition to day, month
1067      * sflux balance is performed on annual basis
1068        (sflxumm, sfluxmm2, bal_sfluxmm)
1069      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
1070        including separate counting and multipliers
1071    o pkg/rbcs
1072      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
1073    
1074    checkpoint58k_post
1075    o testreport:
1076     - always build in dir. "build" (if not there, mkdir build instead of building
1077       & running in input)
1078     - run in dir run (if it exists), in build otherwise.
1079     - call prepare_run (if input/prepare_run exists)
1080     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
1081    o pkg/exf modifications to interpolation and rotation routines for more
1082       reasonable treatment of North Pole singularity: for tracers North Pole
1083       value is set to northernmost zonal-mean value, for zonal velocity it is
1084       set to zero, and for meridional velocity it is set to northernmost value.
1085    o pkg/exf/exf_check_range.F
1086     - add tile index to diagnostics and move stop statement to the very
1087       end of the routine.
1088    o pkg/diagnostics: (diagnostics_main_init.F)
1089      define title of isomorphic variables according to the current config.
1090    o pkg/thsice with pkg/seaice dynamics:
1091    - fix domain of computation (interior only, required for exf) and do exchanges
1092    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
1093    o towards a standard way of dealing with multi-threading in MONITOR
1094      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
1095    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
1096       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
1097    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
1098    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
1099    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
1100       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
1101    o tracer advection:
1102     - clean-up and simplify calc_common_factors.F
1103     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
1104       advection subroutine (but still not used within DST advection S/R)
1105    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
1106    
1107    checkpoint58j_post
1108    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
1109      from file (collects calls previously in FORWARD_STEP)
1110    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
1111    o adjoint store dir. adjusted accordingly
1112    o genmake2
1113      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
1114    
1115    checkpoint58i_post
1116    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
1117      on wind stress (SEAICEstressFactor defaults to 1.)
1118    o Total number of Timers is finite (<=40): comment out 2 non-essential one
1119      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
1120    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
1121      on CS-grid: no longer loosing mass.
1122    o exf & curvilinear-grid: no longer modify longitude xC & xG.
1123    o pkg/ggl90: fix sloppy output and fix a bug
1124    o pkg/seaice: added SEAICEuseEVPpickup parameter
1125      - Set to false in order to start EVP solver with
1126        non-EVP pickup files when using SEAICEuseEVP
1127      - fix sign error in diffusion in seaice_calc_rhs
1128    
1129    checkpoint58h_post
1130    * Modifications for bottom topography control
1131      o replace hFacC by _hFacC at various places
1132      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
1133      o add non-self-adjoint cg2d_nsa
1134      o update autodiff support routines
1135      o re-initialise hfac after ctrl_depth_ini
1136      o works for 5x5 box, doesnt work for global_ocean.90x40x15
1137    * Adding verification for 5x5 box (4-layer) bottom topography control
1138    
1139    checkpoint58g_post
1140    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
1141       used for mean seasonal cycle, mean diurnal cycle); add an example
1142       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
1143    o pkg/ggl90:
1144      - add parameter (minimum surface kinetic energy)
1145      - fix bug (avoiding division by zero)
1146    o couple pkg/thsice to pkg/seaice:
1147      - modify advection in seaice to accomodate new scalar fields to be advected
1148      - only muliDimAdection scheme work with seaice/thsice
1149      - mapping of thsice-variables to seaice-variables, back and forth
1150      - does not break the verification experiments, but does not give the
1151        desired results either
1152    o pkg/seaice
1153      - make (default) second order advection a bit less confusing?
1154    
1155    checkpoint58f_post
1156    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
1157      to pkg/seaice):
1158      - new routines thsice_map_exf and thsice_get_exf provide the interface
1159      - add an additional formal parameter to thsice_solve4temp
1160    o pkg/exf:
1161      - add new fields wspeed, snowprecip (to be able to couple to thsice)
1162      - correct Stefan-Boltzmann constant
1163      - new parameter for longwave surface emittance
1164      - separate some stuff from exf_bulkformulae into new routines  
1165        exf_radiation, exf_wind
1166      - add new parameters and constants: longwave emissivity for ocean, ice
1167        and snow, evaporation parameters over ice
1168      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
1169        either wind from stress or stress from wind
1170    o pkg/thSIce:
1171    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
1172    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
1173       and THSICE_CALC_THICKN
1174    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
1175    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
1176      to make debugging easier.
1177    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
1178    o pkg/bulk_force:
1179      - clean-up comments and parameters ;
1180      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
1181    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
1182      generate new output for test-experiment: aim.5l_cs.thSI
1183    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
1184      testreport accordingly
1185    
1186    checkpoint58e_post
1187    o SEAICE_CGRID adjoint done
1188    o R_STAR adjoint implemented.
1189      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
1190      * need to sort out init. of h0facc, etc.
1191    o Make pkg/profile fully independent of ecco,cost, etc. stuff
1192      to be able to use it in pure forward.
1193    
1194    checkpoint58d_post
1195    o upgrade simple test-experiment to tutorial example:
1196     step.1: duplicate the experiment and (step.2) will remove the old copy.
1197      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
1198      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
1199      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
1200      tutorial_global_oce_biogeo    <- copy of dic_example
1201      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
1202      tutorial_plume_on_slope       <- copy of plume_on_slope
1203      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
1204      tutorial_global_oce_optim     <- empty for now (David ?)
1205      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
1206     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
1207    o correct a sign problem in cost_scat.F
1208    o obcs and ptracers: fix boundary conditions for advections schemes
1209      with larger stencil
1210    o thsice adjoint: start
1211    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
1212      completeness
1213    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
1214      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
1215    o ptracers adjoint:
1216      * avoid extensive recomputatations
1217      * fix missing re-init. of gptr (missed by TAF)
1218    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
1219      me to turn off the excessive output to STDOUT that this package produces
1220    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
1221      and add those terms in Vector-Invariant formulation.
1222    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
1223      if the control period (xx_hfluxperiod etc) is 0
1224    o in profiles pkg, clean routines and fix details
1225    o in ecco pkg, reading ssh data:
1226      fix problem in case the model does not start at iter0=0
1227    o fix mnc-pickup/restart for ptracers
1228    o new package prifiles:
1229      code to compute profile-based cost by Gael Forget
1230      (modifs in ecco, ctrl, autodiff)
1231    o Benign bug fix in initialization (spotted by M. Mazloff) of
1232      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
1233    
1234    checkpoint58c_post
1235    o adjoint: finish NLFS adjoint and provide reference output in
1236      verification/global_ocean.90x40x15/results_ad_nlfs
1237    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
1238      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
1239      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
1240      with SEAICE_CGRID defined.
1241    o move calendarDumps from "data" to "data.cal" and clean-up the code
1242      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
1243    o add useEXF & useCAL flags (for now, set in hard-coded way)
1244    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
1245      (were missing in NH mode, and wrong in quasihydrostatic mode).
1246      waiting for Chris updated version of calc_gw to add those CALLs.
1247    o fix bug in quasihydrostatic S/R ;
1248      add a test for this option: global_ocean.90x40x15.qshyd
1249    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
1250      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
1251    o add on/off flag useOffLine for package OFFLINE
1252    o seaice:
1253      - modify advection so that it works also on the C-grid
1254      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
1255        problem in multi-tile runs with C-grid
1256      - add flags for clipping ice velocities and/or masking solver forcing
1257      - fix drag (ocean on ice) formulation and a bug that caused noise in the
1258        C-grid solver
1259      - added a few comments to seaice_diffusion.F
1260      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
1261        are now exclusive)
1262      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
1263        required re-ordering the code a little:
1264       + make DAIRN global variable (defined in SEAICE)
1265       + move computation of the viscosities eta and zeta into a new separate
1266         routine (because I need to recompute them in seaice_ocean_stress.F)
1267    
1268    checkpoint58b_post
1269    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
1270      update output.txt of exp. aim.5l_cs.thSI
1271    o various mnc cleanups and improvements:
1272      + shrink lookup tables by factor of ~4
1273      + better error reporting when running out of lookup space
1274      + able to handle longer path/file names (up to 500 chars)
1275    o adjoint:
1276      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
1277      - TBD: "hidden" mom_vecinv recomp. in dynamics
1278    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
1279     (allow to differentiate between forcing components using new integer flags:
1280      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
1281     and add new flag to put Dissipation tendency out of Adams-Bashforth.
1282    o ecco
1283      - enable trend removal from SSH anomaly obs.
1284    o adjoint
1285      - a fix for PmEpR when #undef EXACT_CONSERV
1286      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
1287      - try to fix "hidden" recomp. in forward_step for NLFS
1288        (NLFS seems broken sometimes after I checked it in)
1289    o seaice:
1290     - add c-grid version of the dynamic solver:
1291       + three new routines that are the c-grid substitute lsr, dynsolver
1292         and ostres
1293       + put a few fields that were local to dynsolver into global common
1294         blocks, so that I can move the computation of stresses etc into
1295         seaice_lsr (saves coding but may break the adjoint).
1296     - replace more hardwired parameters by runtime parameters
1297     - add ice masks that mask the rhs of the implicit solvers where there
1298       is no ice (commented out in seaice_dynsolver, because i am not sure
1299       if this works properly), eventually this should replace the clipping
1300       of ice velocities in seaice_dynsolver to +/-40cm/s.
1301    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
1302      include it only where its needed
1303    o move balancing of fluxes before the call of external_forcing_surf
1304    o seaice:
1305      - correct units of turning angles (now they are really in degrees)
1306      - move computation of GWATX/Y out of main routine into dynsolver
1307      - initialize GWATX/Y in seaice_init
1308    o Apply mask on Fresh-Water flux (needed for SSH forcing).
1309      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
1310    o seaice: add runtime flags for turning angles (default to zero)
1311    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
1312      and trend from exf forcing and ctrl control adjustments
1313    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
1314      (since checkpoint57x_post)
1315    o change the default rotation period to 86164.s = the Earth rotation
1316    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
1317      and based on a reference stratification. Tested within hs94.cs-32x32x5.
1318    o seaice advection: add code for choosing between the default (2nd order
1319      central differences) and multiDim advection schemes provided by
1320      pkg/generic_advdiff
1321    o seaice:
1322      - removed all references to SEAICE_GRID.h fields from
1323        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
1324        (cubed-sphere configuration will change a little)
1325      - grid computations in seaice_init are obsolete now.
1326      - cleaned up code a little so that is easier to read (hopefully).
1327      - added new (better?) discretizations of default advection and diffusion
1328        (turn on with SEAICEuseFluxForm)
1329      - replace 1 in 3d global fields by kSurface in growth.F
1330      
1331    checkpoint58a_post
1332    o seaice:
1333      - bug fix in advect.F
1334    o shelfice:
1335      - separate shelfice load anomaly from pload (breaks with time
1336        dependent forcing), => introduce constant field shelficeLoadAnomaly.
1337        Its default is 0., but it may be computed more cleverly from (unknown)
1338        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
1339        done offline. A good approximation of the pressure load anomaly is
1340        necessary to avoid large initial adjustment processes underneath
1341        deep-reaching shelfice.
1342      - small fix in ISOMIP shelfice_thermodynamics
1343      - add more sophisticated thermodynamics of Hellmer (1989), this is
1344        now the default
1345      - give a few constants more intuitive names
1346    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
1347      if bulk formulae are used in long integration (especially EmPmR). Turn
1348      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
1349      if balancePrintMean, the imbalance that is substracted is printed to
1350      STDOUT.
1351    o fix bug (typo) in obcs_apply_eta.F
1352    o add a new package shelfice which enables us to model the circulation
1353      underneath shelf-ice with draughts of hundreds of meters.
1354     - works
1355     - to do: + include improved thermodynamics
1356              + check whether kSurfC (from model/inc/SURFACE.h) can be used
1357                instead of new field kTopC
1358              + can we use topoFile, Ro_surf and existing code in ini_depth.F
1359                instead of new field R_shelfIce and new code in ini_depth.F
1360                and ini_mask_etc.F?
1361              + adjust vertical mixing schemes?
1362    o seaice pkg:
1363     - add a cpp-flag to include a simple formula for a salinity dependent
1364       freezing point of sea water at the surface
1365     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
1366       meridional stresses are now different (and hopefully correct)
1367    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
1368       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
1369       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
1370    o pkg/diagnostics: add options and parameters for regional-statistics
1371       diagnostics ; define regions by reading a region-mask from a file
1372       (might add other options later)
1373    o pkg/bulk_force:
1374     - add option and parameters to use AIM surface-flux formulae.
1375     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
1376       others forcing fields (defined in PARM05, parameter file "data") are loaded
1377       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
1378     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
1379     - use the right EXCH call for uwind,vwind (to work on CS-grid).
1380     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
1381       and parameters (note: calcWindStress replaces .NOT.readwindstress).
1382     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
1383    
1384    checkpoint58
1385    o add "--embed-source" option to genmake2 which, when the supporting
1386      tools can be compiled (as determined by genmake2) will turn on the
1387      embed_files package which then embeds the entire MITgcm source code
1388      (*.[fFhc] + Makefile) used for the build within the executable
1389      - requested by CNH but off by default
1390      - adds a paltry <9MB to the mitgcmuv executable in most cases
1391      - only writes the output when useEMBEDSRC in eedata is true
1392    o clean up 3-dim. relaxation codes:
1393      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
1394      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
1395      * Thanks to Tom Haine for testing!
1396    
1397    checkpoint57z_post
1398    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
1399      affects output (@ truncation level) of exp. plume_on_slope ; updated.
1400    o fix the pickup behavior for obcs in combination with ptracers
1401    o fix a bug in ptracers_external_fields_load
1402    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
1403      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
1404    o transfered surface NH pressure to eta field (if exactConserv).
1405    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
1406         and update lab_sea output.txt file.
1407    o completing 3-dim. relaxation code: additional term
1408         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
1409      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
1410      * At compile time, in "EXF_OPTIONS.h" set
1411          #define  ALLOW_CLIMTEMP_RELAXATION
1412          #define  ALLOW_CLIMSALT_RELAXATION
1413      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
1414          tauThetaClimRelax3Dim = 15552000.0,
1415          tauSaltClimRelax3Dim  = 15552000.0,
1416      * 3 cases:
1417          1) Use a constant-in-time 3-dim. field
1418          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
1419          3) Real-time relax. to time-evolving prescribed field
1420    o Adding Laplacian-type smoothness constraint on
1421      initial and boundary (forcing) controls (ic, bc)
1422      * enable at compile-time via
1423        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
1424      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
1425      * Absolute scale somewhat unclear so far
1426      * no area weighting was included since no other cost term does so far
1427    
1428    checkpoint57y_post
1429    First step for a NLFS adjoint
1430    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
1431    o new init. routines for calc_r_star, calc_surf_dr
1432    o still need to deal with ini_masks_etc
1433    o testreport seemed happy
1434    checkpoint57y_pre
1435    
1436    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
1437    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
1438    o add new offset feature to offline pkg (plus minor cleanup)
1439    o cfc fixes for final year of integration
1440    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
1441      be in GCHEM_OPTIONS).
1442    
1443    checkpoint57x_post
1444    o fix testreport Pb in multiple test experiment.
1445    o cleanup our namelist syntax in verification:
1446      - make it more F95 standards compliant (some work still needed)
1447      - allows the vast majority of our tests to work with gfortran
1448    o Non-Hydrostatic:
1449     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
1450     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
1451    o Allow to apply AB on T,S rather than on AB(gT,gS):
1452     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
1453     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
1454       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
1455     - need a "clever" read_pickup to restart from the other AB formulation
1456    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
1457    o remove some unused variables (reduces number of compiler warnings)
1458    o adjoint
1459      * Disable useVariableViscosity for adjoint for time being
1460        (there are a number of extensive recomputations)
1461      * Initialize certain variables needed for adjoint
1462    
1463    checkpoint57w_post
1464    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
1465                 fix the singleCpuIO RS version of MDSWRITEFIELD
1466       and add a WARNING if using globalFiles=T with multi-processors.
1467    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
1468      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
1469    o tracer advection scheme:
1470      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
1471       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
1472       was not very convenient).
1473      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
1474       (further tests needed for the implicit DST & Flux-Limiter schemes).
1475    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
1476      and sRef for convenience, handy, when you want to initialize
1477      ptracers in a large domain with a constant non-zero value. Also,
1478      untangle ptracers_init.F a little.
1479    
1480    checkpoint57v_post
1481    o change dome exp. to use variable viscosity in side-drag terms.
1482    o remove all the files from the cfc_offline test since they are now
1483      incorporated into tutorial_cfc_offline which has been producing
1484      identical results for a few days of testing
1485    o add new parameter: sideDragFactor to enable half-slip-side BC
1486      and change side-drag S/R to use viscosity from mom_calc_visc
1487      (can switch back by setting sideDragFactor=0.); affects results at
1488      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
1489       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
1490    o vorticity & strain are now computed without masking, to account for
1491      no-slip-side BC in variable viscosity calculation ; mask is applied
1492      anyway later on, before computing advection/coriolis terms.
1493    o modify exp4 to test new obcs support for reading from external files
1494      and for passive tracers
1495    o fix behavior of ptracers_monitor when monitor output is written to a
1496      netcdf-file; still not independent of monitor.F (writes in the same
1497      file).
1498    o change default value of tRef (put a uniform, meaningful value for ocean
1499      & atmos) and initialize sRef (was missing, as Martin mentioned).
1500    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
1501      to be proportional to enstrophy dissipation length.  Thus,
1502       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
1503      This is now consistent with Smagorinsky and with the manual.
1504    
1505    checkpoint57u_post
1506    o OBCS and PTRACERS: add open boundary support for passive tracers
1507      - either use homogenous (pseudo) v.Neumann conditions or prescribe
1508        OB-values from file; this is not different from the way theta and salinity
1509        are treated
1510      - however, Orlanski-radiation conditions are not supported, and the model
1511        will stop if you use pTracers and Orlanski at the same time.
1512      - beefed up the rountine obcs_external_fields_load: now only those open
1513        boundary values are overwritten with values from files for which there
1514        are really files, otherwise the OB-fields remain untouched. This makes
1515        it possible to use different OBs at different ends of the domain (as
1516        with EXF)
1517    o reduce number of exch calls in shap_filt (s2).
1518    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
1519      truncation level) 4/5 MLAdjust test results (11&12 digits match).
1520    
1521    checkpoint57t_post
1522    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
1523    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
1524      same truncation, independent of the face number: affects affects several
1525      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
1526    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
1527      note that biharmonic viscosity + no-slip was not tested in any experiment.
1528    o fix bug in non-linear free-surf side-drag ; generate new output for
1529      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
1530    o make mnc honor the writeBinaryPrec flag for most kinds of output
1531    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
1532    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
1533      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
1534    o add brackets in multi-terms sum to get same truncation, independent of
1535      the face number (manage to get exactly same value of gU,gV at the cs-edge)
1536      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
1537    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
1538      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
1539      a maximum grid-scale Reynolds number.  Also, changes all length calculations
1540      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
1541      Suggested values of viscosity parameters found in mom_calc_visc.
1542      Many new viscosity diagnostics available.
1543    
1544    checkpoint57s_post
1545    o Add clearing-house for viscosity calculations, mom_calc_visc and
1546      correct numerous bugs in LeithD and Smagorinsky discretizations.  
1547      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
1548      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
1549      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
1550      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
1551      The Strain-Tension form is now called with useStrainTensonVisc=.true.
1552      ViscAhStrain and viscAhTension are now retired.
1553    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
1554    o In response to JMC's bug report, genmake2 now ignores any soft-links
1555      that it finds in the *current* directory when searching for files.
1556      Soft-links found in any other source directories will still work as
1557      they did before.
1558    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
1559      a C routine to unlimit the stack size
1560    o mnc-ify pkg/aim snapshot vars
1561    o mnc-ify pkg/land as requested by Daniel
1562    o various changes to mnc including:
1563      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
1564      - output can now be grouped so that all files within a group
1565          change the ITER portion of their names in lock-step together
1566      - can now read ("global") PER-FACE (in addition to PER-TILE) files
1567          and works with both EXCH1 and EXCH2 (but needs more testing)
1568      - writing works for all verification test cases w/ g77 on Linux
1569    
1570    checkpoint57r_post
1571    o make MNC variable initialization happen earlier
1572    o add diagnostics for (almost) each term of the momentum Eq.
1573    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
1574    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
1575    o remove MINIMAL_TAVE_OUTPUT option ;
1576      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
1577    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
1578      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
1579    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
1580    o add time-dependent SST, SSS control
1581    o cost terms in ecco/ modularized (new cost_generic.F)
1582    o cost_averages routines are modularized (new cost_averagesgeneric.F)
1583    o new infrastructure for seaice model vs. obs misfits in seaice/
1584      * driver from the_main_loop.F is seaice_cost_driver.F
1585      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
1586      * gradient check in Exp. 6a of natl_box_adjoint/
1587    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
1588      (see README file)
1589    
1590    checkpoint57q_post
1591    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
1592    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
1593      - bug was reported by Jean-Michel and Ian Fenty
1594    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
1595      update exp. cpl_aim+ocn output.
1596    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
1597      Needed for high-res. runs with large global files
1598      to be able to limit tapelev size
1599    o Changed some tests for adjoint:
1600      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
1601      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
1602      * global_ocean.90x40x15/ back to default 3-level checkpointing
1603    o Modifications to enable scripted COMMON to MODULE conversion
1604      * verification/OpenAD/code/ has necessary scripts and description;
1605      * converts, compiles and runs successfully;
1606    
1607    checkpoint57p_post
1608    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
1609    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
1610      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
1611    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
1612    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
1613      (was already the case for dissipation with mom_vecinv,
1614       and also the case for grad.PhiHyd when staggered-timeStep)
1615      This will allow to put dissipation out-off the AB time-stepping.
1616     Unfortunately, affects truncation error. Update output of exp. that "fails"
1617      (cg2d matching number) and leave the others for later: front_relax(10),
1618      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
1619      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
1620    
1621    checkpoint57o_post
1622    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
1623      (2) its ready to be documented during the 20050801 DocFest
1624    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
1625      for ideal_2D_oce and lab_sea on linux_ia32_g77
1626    o set to #undef CTRL_SET_OLD_MAXCVARS_30
1627      in global1x1_tot/code_seaice_adj to access indices 32, 33
1628      (worth another tag)
1629    
1630    checkpoint57n_post
1631    o adding precip control xx_precip 32
1632    o adding swflux control xx_swflux 33
1633    o Replacing 10 forcing penalty cost routines by 1 generic.
1634    o Implementing partitioning in time-mean and variable adjustment
1635      for atmos. state.
1636    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
1637    o in natl_box_adjoint:
1638      * updated exp 1 to 10
1639        (but does not have time-mean vs. variable split results yet)
1640    o updated global1x1/*_seaice_adj/
1641      to incorporate latest changes
1642    o enable useSingleCpuIO for mdsio vector routines
1643      (applies in particular to tapelev I/O)
1644    o removed inefficient K-loop in all active_file*control*.F
1645    
1646    checkpoint57m_post
1647    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
1648      and advect_cs (use EXCH-2 and standard cs-32 grid files).
1649    o pkg/exch2: filling of face-corner halo regions is optional
1650      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
1651    
1652    checkpoint57l_post
1653     tag before updating tutorials (pre-release-2)
1654    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
1655       for output and interpolation of input fields onto model grid)
1656    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
1657       Affects results of exp. rotating_tank ; update output.txt.
1658    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
1659          and taking the square quantity and/or using a fraction-weight field.
1660    o fix aim_diagnostics_init.F mate numbers.
1661    o add mnc output capability to diagnostics/diagstat and update
1662      our cvsignore files for the ACSII output generated
1663    
1664    checkpoint57k_post
1665    o lab_sea now uses diagnostics package and provides a suite of
1666      new EXF diagnostics output.
1667    
1668    checkpoint57j_post
1669    o exf
1670      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
1671        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
1672        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
1673      * extended diagnostics output
1674        - now includes all EXF variables
1675        - hs, hl moved to common block
1676        - separate S/R for diagnostics, called after ctrl vector is added
1677        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
1678        - EXFqnet contains true Qnet (i.e. includes qsw)
1679      * updated verif. lab_sea, global_with_exf
1680      * Rearranging hflux (exf_mapfields -> exf_getforcing)
1681        to ensure that diagnostics sees a true EXFqnet
1682    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
1683    o diagnostics pkg: change pointers so that 1 diagnostic can be used
1684      several times with different frequencies.
1685    o mnc-ify the thsice package as requested by Daniel Enderton
1686      - the monitor--MNC output needs work
1687      - many attributes need to be added (most are currently blank)
1688    o mnc-ify theaim_v23 package as requested by Daniel Enderton
1689      - many attributes need to be added (most are currently blank)
1690    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
1691    o add Sadourny like discretization to the 4th.O vorticity advection scheme
1692    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
1693      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
1694         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
1695    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
1696     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
1697    
1698    checkpoint57i_post
1699    o Diagnostics package was changed: diagnostic allocation is now deactivated
1700      by setting an empty file name in the namelist (used to be by setting 0 frequency)
1701    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
1702      add 1rst Order upwind vertical Shear.
1703    o add a quick fix for A/B checkpointing in OFFLINE mode
1704    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
1705      end-run around the C/Fortran linking horror in eesup/src/timers.F
1706    o added pkg/runclock: allows user to terminate run based on wall clock
1707    o added non-hydrostatic scaling parameter: nh_am2
1708    o pkg/my82: futile attempt to make results compiler-independent by adding
1709      some "_d 0", etc. no effect.
1710    o for mnc output, fill the 'T' coordinate var with myTime and create a
1711      separate 'iter' variable for iteration count
1712    o pkg/diagnostics:
1713      add new capability: output of Global/Regional & per-level statistics ;
1714      tested against monitor output (including land & thSIce) on various exp.
1715    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
1716    
1717    checkpoint57h_done
1718      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
1719      data.diagnostics, data.gchem, data.ptracers) is done.
1720    
1721    o pkg/diagnostics: prepare for Global/Regional statistics.
1722      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
1723    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
1724      and rename it: DIFFERENT_MULTIPLE
1725    
1726    checkpoint57h_post
1727    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
1728    o pkg/diagnostics: change output frequency, now in seconds (instead
1729      of Nb of iterations). This requires to change data.diagnostics.
1730    checkpoint57h_pre
1731    
1732    o in mnc, let the user create the output dir if both mnc_outdir_date
1733      and mnc_outdir_num are false
1734    o add fflags() to pkg/diagnostics which allows one to specify, on a
1735      per-file basis, the file precision [default behavior is unchanged]
1736    o added diagnostics to pkg/kpp, including computation of mixed layer
1737      depth based on a temperature/density criterion
1738    o updated verification/natl_box to test the new pkg/kpp diagnostics
1739    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
1740    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
1741    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
1742      not mnc -- this mistake was found by JMC and is now corrected
1743    
1744    checkpoint57g_post
1745    o add Adams-Bashforth 3rd Order time stepping:
1746      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
1747      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
1748    checkpoint57g_pre
1749    
1750    o make lambda[Theta,Salt]ClimRelax spatially varying
1751      (default remains spatially uniform constant based on tau)
1752    o added new control variables
1753      * init. uVel, vVel, etanN
1754      * lambda[Theta,Salt]ClimRelax
1755    o separate masks used for ctrl_pack/unpack 'from write_grid' output
1756      (suggested by G. Forget)
1757    
1758    checkpoint57f_post
1759    o add parameter "baseTime" = model base time = time at iteration zero
1760      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
1761      account for baseTime shift
1762    o move Coriolis arrays from PARAMS.h to GRID.h
1763    checkpoint57f_pre
1764    
1765    o mnc-ifying the seaice package
1766    o introduced an alternative length scale calculation for use in the limiting
1767      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
1768    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
1769    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
1770      as well as grad(vort3).  Made it compatible with both approximate form
1771      for the cubed sphere and full form of these gradients.  Added flag
1772      useFullLeith to select between approximate and full form.  
1773    o add "d0" in getcon.F to reduce differences between compilers/platforms
1774      update output.txt of exp. fizhi-gridalt-hs
1775    o change port_rand funtion to allow to set the seed.
1776    o fix obscure MNC bug involving conversion between reals and integers
1777      - it caused no problems with certain (eg. gcc, ifc) compilers but the
1778        new version is now more standards-compliant
1779    o adjoint-related modifications
1780      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
1781      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
1782      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
1783    
1784    checkpoint57e_post
1785    o Adding eddy stress controls a la Ferreira et al.
1786    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
1787    
1788    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
1789      update output.txt of exp. fizhi-gridalt-hs
1790    o add more "Z" dimensions and associated coordinate vars to MNC
1791    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
1792    o parameter calendarDumps: when set, approximate months (30-31 days) and years
1793      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
1794      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
1795      months and years.  Requires pkg/cal.
1796    o diagnostics: add pickup functionality
1797      - off by default for backwards compatibility
1798      - current version only uses MDSIO -- MNC will be added
1799    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
1800    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
1801    
1802    checkpoint57d_post
1803    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
1804    o modify verification/ideal_2D_oce so that it tests the creation of mnc
1805      output from the diagnostics package
1806    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
1807    o make genmake2 more portable by using ".$FS" instead of ".f" for more
1808      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
1809    o add coordinate variables to the MNC output from the diagnostics package
1810    o change MNC-flags default value: true when useMNC=TRUE
1811    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
1812      the ability (off by default) to read the grid information using MNC
1813    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
1814    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
1815    o do snap-shot diagnostics at the middle of the time-interval (instead of
1816      at the end).
1817    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
1818      new test for AIM with thSIce + slab-ocean
1819    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
1820    o move state variable diagnostics to the beginning of the time step ;
1821      (note: still needs some work specially for snap-shot diagnostics)
1822      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
1823    
1824    checkpoint57c_post
1825    o Change testing option (-ieee) to get closer agreement between g77 & ifort
1826    o generate new output.txt files on faulks with g77 & the new -ieee option
1827    checkpoint57c_pre
1828    
1829    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
1830      update output.txt of exp. global_ocean.90x40x15
1831    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
1832      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
1833    o add saltFlux(+File) forcing capability with periodicExternalForcing
1834    o allow to use pkg diagnostics for GM-Redi & ThSIce output
1835    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
1836    o improvements for the MNC output from DIAGNOSTICS:
1837      - correct handling of the unlimitied dimension
1838      - all dims now have associated coordinate variables
1839      - variables located at U, V, and Corner ("Z") points are now written
1840        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
1841        *all* data points are output
1842    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
1843    o added pkg/seaice/seaice_monitor.F
1844    o mdsio_readfield.F can now read files visible only to master MPI process.
1845    o pkg/seaice: some test code for ice-modified ocean stress
1846    o exf_getffields interpolation defaults to bilinear for all scalar forcing
1847      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
1848      spurious negative numbers for precipitation and humidity.  Will cause
1849      some small numerical differences for integrations using pkg/exf/exf_interp.F.
1850    o pkg/ctrl/
1851      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
1852        May be enabled via doPackDiag
1853      *  introduce z-scaling of
1854         + gradient (doZscalePack) and
1855         + control (doZscaleUnpack)
1856    o pkg/mdsio/
1857      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
1858      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
1859    
1860    checkpoint57b_post
1861    o simplify options in diagnostics_fill arguments (remove weird combinations)
1862    o fix MNC coordinate variables so that they now contain per-face index
1863      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
1864      general, EXCH2 grids are only aligned to a "local" coordinate system
1865    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
1866    o Implement instantaneous output within pkg diagnostics:
1867      setting a negative frequency in data.diagnostics produces
1868     "snap-shot" output (as opposed to time-average if freq > 0)
1869    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
1870      NOTE: change ptracer diagnostics name: use 2 characters to work with
1871            more than 9 tracers. Add also diagnostics of advect & diffus flux.
1872    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
1873      becomes the coordinate variable for the 'T' dimension
1874    o add CF-style coordinate variables to MNC
1875      - just a first cut:  numbers are meaningless on the cubesphere and
1876        missing along the T axis but otherwise it works!
1877    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
1878    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
1879    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
1880      this is based directly on what the model compute, so that the content of
1881      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
1882    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
1883    o clean up build options files for SunOS, in particular
1884      - remove -traditional from xmakedepend
1885      - change -xarch=v9 to -xarch=native for f77
1886      - restore use of make (not gmake)
1887      - add CC=gcc if using g77
1888    o changes per discussion of AM, JMC, & EH3 today:
1889      - move redundant "grid" variables out of "state" -- in preparation of
1890        creating proper CF-style coordinate variables and in recognition
1891        that any/all grid variables can be easily copied (eg. w/NCO) from
1892        the grid files into any of the other NetCDF files
1893      - *always* output grid variables with MDSIO (this will eventually be
1894        changed)
1895      - output MNC grid file if useMNC is true
1896    o every instance of _END_MASTER() has been found and replaced with
1897      _END_MASTER( myThid ) in order to satisfy certain picky Sun
1898      preprocessors
1899    o re-arrange diagnostics pkg initialisation:
1900     - allow each package to extend the available diagnostics list
1901     - add some checking and fix small problems (multi-threaded, ...)
1902     - new S/R diagnostics_fill (replace fill_diagnostics):
1903       look through the short list of active diag. (instead of the long list)
1904       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
1905    
1906    checkpoint57a_post
1907    o this set of changes restores TAMC compatibility
1908      tested for global_ocean.90x40x15 adjoint on trough
1909      (what a pain)
1910    
1911    checkpoint57a_pre
1912    o some modifs in tools/build_options for sunos
1913    o call ctrl_pack for ctrl at end for optimcycle=0
1914    
1915    checkpoint57
1916    o add horizontal bi-harmonic viscosity for vertical velocity
1917      - new parameter viscA4W (defaults to viscA4)
1918      - affects only non-hydrostatic code
1919      - to be done: no-slip lateral boundary conditions
1920    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
1921    o implement Implicit Vertical advection for pTracers
1922    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
1923      (implemented also for implicit vertical diffusion & advection)
1924    o OBCS: extend application of tracer open boundary conditions
1925      to a strip beyond the boundary of width Olx/Oly
1926    o add call monitor to TAF set of required calls (flow directives)
1927      and include in natl_box_adjoint
1928    o untangle a few ifdefs related to cost, ctrl, autodiff
1929      untangel a few ALLOW_ECCO_OPTIMIZATION
1930    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
1931      (theta2, salt2 in ecco_cost_weights)
1932    
1933    checkpoint56c_post
1934    o OBCS as control variables
1935      - update ctrl_ad_diff.list, obcs_ad_diff.list
1936      - remove balance of obcs controls from default
1937      - fix index bug nobcs in ctrl_init
1938      - fix dummy fields filen in ctrl_pack
1939      - add dummy weights for obcs
1940    o lsopt: comment out fort.94 output
1941    o optim:
1942      - remove unnecessary header files
1943      - adjusted namelists
1944      - add xerbla.F to Makefile
1945    o exf:
1946      - multiple modifications of exf_check_range
1947      - unit change in exf_init_runoff from [m/year] to [m/s]
1948    o mdsio:
1949      - i/o-vector change debugLevel from debLevA to debLevB
1950    
1951    checkpoint56b_post
1952    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
1953      is called from DO_THE_MODEL_IO
1954      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
1955      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
1956      - clean up PTRACERS_WRITE_TIMEAVE a little
1957    o add another verification experiment that tests both the cfc-pkg and
1958      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
1959      reactive tendencies treated inline with regular timestepping
1960    o testreport previously did a lousy job of comparing small numbers, so
1961      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
1962      implemented in the little c-progam tmp_cmpnum.c which is embedded in
1963      testreport.
1964    o ptracers_monitor: bug fix for MPI
1965    
1966    checkpoint56a_post
1967    o GCHEM: finish reorganizating the package
1968      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
1969        (introduces another 3D-array for each passive tracer, but only if
1970        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
1971        gchemTendency is not needed because the timestep is done separately)
1972      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
1973      - GCHEM is now---more or less cleanly---separate from PTRACERS
1974      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
1975        so clear to me how that should be done in a general way.
1976    o CFC: improve formatting of output in CFC_ATMOS
1977    o PTRACERS:
1978      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
1979        that ALL experiments with ptracers enable can be checked. This makes
1980        GCHEM_MONITOR obsolete.
1981      - include a runtime parameter PTRACERS_monitorFreq that defaults to
1982        monitorFreq
1983      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
1984    o add PTRACERS (PTR0[1-5]) to testreport output
1985    o exf_check_range:
1986      * default changed to .TRUE.
1987      * will check values for niter0 if debLevA, every timestep if debLevB
1988      * STOP in exf_check_range if 'out of range'
1989      * range chosen generous to allow for potential extema
1990      TBD: a version with stricter range
1991           permitted range would be runtime parameters
1992    o GMredi:
1993      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
1994      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
1995      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
1996    o GCHEM:
1997      - move call to GCHEM_FORCING_SEP, so that it is now called before
1998        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
1999      - introduced a useGCHEM runtime flag and applied it everywhere.
2000      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
2001        this flag is now only visible within GCHEM-pkg routines.
2002      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
2003        be replaced by a 3D array that is computed before thermodynamics; for
2004        this, the tracer ID iTracer had to be included into the parameter list
2005        of ptracers_forcing
2006      - set up forward_step to call gchem_forcing, that will replace
2007        gchem_forcing_int in ptracers_forcing
2008      - cleaning up
2009    o small cleaning of exch2: remove files that are also in eesupp/src
2010    
2011    checkpoint56
2012    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
2013    o mnc: cleanup "full" files--fixes out-of-memory problem
2014    o ECCO-GODAE
2015      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
2016      * fully merged and updated from SIO code
2017        windstress sign change affects
2018        - exf_inscal_[u/v]stress
2019        - sign of xx_tau[u/v] adjustments
2020        - signs in cost_scat
2021      * ctrl_get_gen: avoid update of tau[u/v] for first few days
2022      * natl_box_adjoint updated and compressed
2023      * 2-level checkpoint switch added
2024        (tested in EXP. 1 of natl_box_adjoint)
2025      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
2026    o SVD
2027      * first complete, non-hacked version for SVD calculations
2028      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
2029        performed via direct access files admtlm_vector.it????
2030        (via ctrl_[un]pack)
2031      * optimcycle is used for ARPACK iteration counter
2032        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
2033      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
2034        and add linear transforms where necessary
2035      * controls are initial/final SST, SSS (can be extended; need to check
2036        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
2037    o mdsio: filename info to both stderr, stdout
2038    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
2039      from sign change
2040    
2041    checkpoint55j_post
2042    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
2043      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
2044    o add consistent build directories and .cvsignore files to verification
2045    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
2046    o make all subroutines 30 or less characters in length for certain older
2047      compilers to work (a thorough search only turns up two routines in
2048      pkg/ptracers)
2049    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
2050      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
2051    
2052    checkpoint55i_post
2053    o change arrays for total vertical diffusivity (2.D if explicit,
2054      3.D if implicit) ; each ptracer uses its own background value.
2055    o added mnc/NetCDF output capability to ocn_compon_interf
2056      - added bits to verification/cpl_aim+ocn so that it can run on
2057        ITRDA and other clusters without the mpirun "-wd" option
2058    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
2059      configuration
2060    o give MNC the ability to create additional files rather than
2061      exceeding a specified file size limit "MNC_MAX_FILESIZE"
2062      - the default is just less than 2GB which is a practical limit
2063        on many systems
2064    o Compute the non-local term using either KPP vertical diffusivity (=default)
2065       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
2066    
2067    checkpoint55h_post
2068    o add verification test "vermix"
2069    o remove all the *_ioinc flags and replace with the single global
2070      outputTypesInclusive flag
2071    o allow to set a vertical profile of vertical diffusivity for T & S
2072    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
2073    o useMNC moved from data.mnc to data.pkg
2074    
2075    checkpoint55g_post
2076    o Renaming carbon AD experiments to comply with testreport conventions
2077    o Updating adjoint of Held-Suarez hs94.1x64x5
2078    o Fixing directives for non-ECCO forward_step, after ECCO directives
2079      have been fixed to avoid recomp. of do_oceanic_phys
2080      Works well for global_ocean.90x40x15,
2081      but recomp. issue remains for carbon
2082    o Updating adjoint output for natl_box_adjoint after
2083      pkg/ecco has been modified (see taga c55d_post)
2084    
2085    checkpoint55f_post
2086    o rename to timeave_init_fixed
2087    
2088    checkpoint55e_post
2089    o some delicate re-shuffle of store directives to avoid one
2090      extra call of do_oceanic_physics
2091      affects ecco_the_main_loop.F, do_oceanic_physics.F
2092      checkpoint_lev1_directives.h
2093    o NB: this may break global_ocean adjoint temporarily,
2094      but it is clear how to fix it. Will do later, need this now.
2095    
2096    checkpoint55d_post
2097    o ECCO specific cost function terms (up-to-date with 1x1 runs)
2098    o ecco_cost_weights is modified to 1x1 runs
2099    o modifs to allow observations to be read in as
2100      single file or yearly files
2101    o enable to read exf forcing fields as either
2102      single file or yearly files (flag useExfYearlyFields)
2103    checkpoint55d_pre
2104    
2105    o switch between 2-level and 3-level checkpointing
2106    o add ability of MNC to write local and "partial" (eg. 2D slices where
2107      the full 3D field is never actually stored) arrays to NetCDF files
2108      with the correct (that is, the complete multi-dimensional) set of
2109      array indicies
2110      - used in mom_vecinv() to write the diagFreq output
2111      - tested (demonstrated) in verification/aim.5l_cs
2112    o further mnc-ification
2113      - add verification/lab_sea to the list with mnc setups
2114      - fix undefined mnc v-names in cd_code
2115      - add kpp to mnc output (both snapshot and timeave)
2116    o non-hydrostatic code
2117      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
2118        in calc_gw.F
2119      - defaults to viscAh
2120      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
2121        friction or Leith) in non-hydrostatic mode, as long as there is
2122        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
2123    o pkg/cost
2124      extend simple cost functions to treat time mean quantities
2125      (T,U,V) via cost_accumulate_state from cost_tile
2126    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
2127        be 2 times larger than the minimum size the advection scheme requires.
2128        now get a perfect conservation of salt in advect_cs test-exp (updated)
2129    o GGL90 (Gaspar's TKE mixed layer)
2130      - add horizontal diffusion of TKE, requires exchanges in
2131        do_fields_blocking_exchanges, horizontal diffusivity is zero by
2132        default. In OPA there is no horizontal diffusion of TKE but the
2133        mixing coefficients are computed from a horizontal average of TKE of
2134        6 points or so. I think that diffusion has a little more physical
2135        justification.
2136      - clean up ggl90_calc in the hope of reducing memory usage (this hope
2137        was in vain)
2138      - mask tke-variable in ggl90_init
2139    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
2140    o fix biharmonic diffusion on CS-grid.
2141    o more obcs stuff
2142      - added obcs_external_fields_load as an alternative to the EXF-pkg option
2143        for reading boundary values. This routine is called from
2144        obcs_prescribe_read
2145      - updated obcs_check
2146      - changed sponge layer relaxation parameter units for days to seconds
2147      - turned off sponge layer by default
2148      - changed argument list of OBCS_CALC to myTime+deltaTclock
2149      - fixed about 35 bugs in obcs_external_fields_load
2150    
2151    checkpoint55c_post
2152    o obcs stuff
2153      - new runtime flags useOBCSprescribe, useOBCSbalance
2154      - re-arranged obcs_calc
2155      - moved exf_getobcs to obcs_prescibe_read
2156        obcs_prescibe_read is called after ORLANSKI stuff
2157        and independent of it (executable can contain all).
2158      - updated obcs_check
2159      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
2160        These may be necessary only if tangential velocities are
2161        prescribed at OB, not sure, needs testing.
2162    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
2163      which simplifies the calls and passes the ifc check-bounds test
2164    
2165    checkpoint55b_post
2166    o add a 2D scalar, Z location, exchange_2 routine.
2167    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
2168      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
2169      affects advect_cs results (for the wrong reason): update output.txt
2170    o use a more standard discretization for biharmonic viscosity ;
2171     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
2172      affects results of dome set-up: update output.txt
2173    o fix gad_advection.F (CubedSphere part), back to version 1.23
2174    o fix bug in mom_vi_del2uv.F (CubedSphere part).
2175    
2176    checkpoint55a_post
2177    o merged code to
2178      * prescribe/read time-dependent open boundaries
2179        (works in conjunction with exf, cal)
2180      * sponge layer code for open boundaries
2181      * each boundary N/S/E/W now has its own CPP option
2182        (healthy for the adjoint)
2183    
2184    checkpoint55
2185    o up-to-date adjoint of previous breaks
2186      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
2187      - global_ocean_ebm: adjoint still needs fix (TLM ok)
2188      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
2189      - carbon: * remove tr1-related adjoint verification
2190                * add ptracer as control variable
2191    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
2192      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
2193    
2194    checkpoint54f_post
2195    o in verification/carbin/ remove experiment related to
2196      ALLOW_PASSIVE_TRACER (array tr1 etc)
2197      code_ad/ input_ad/ results_ad
2198    
2199    o add two new packages
2200      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
2201        + subject to optimization (memory)
2202      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
2203        + subject to reordering (many GOTOs in the original code)
2204        + so far opps is called for every (i,j) point, and then operates in
2205          the vertical; one may want to reorder the scheme in order operate in
2206          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
2207          fields)
2208    o overhaul of IO so that we now have flags for MDSIO and/or MNC
2209      - all verification tests compile and run with linux_ia32_g77
2210      - defaults are compatible with current input files--nothing
2211        should change if you were not previously using MNC
2212      - MNC output has been added in numerous places (eg. timeave)
2213        but there are still a few writes not yet do-able with MNC
2214        (this is in progress)
2215      - flags now allow for either/or/both use of MDSIO and MNC and
2216        documentation will soon follow
2217      - numerous small formatting cleanups for ProTeX
2218    o add version info (via BUILD_INFO.h) to MNC and stdout
2219    
2220    checkpoint54e_post
2221    o add two new packages
2222      - pp81 (Packanowski and Philander, 1981), Richardson number and
2223        stratification dependent mixing
2224      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
2225      - these scheme operate in a similar manner as KPP (without ghat, of
2226        course), however there is only one diffusivity that is used for both
2227        temperature and salinity (and passive tracers)ç
2228    o add offline package
2229    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
2230      provided by Stephanie Dutkiewicz
2231    o genmake2: add ability to search for C compilers and cleanup test output
2232      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
2233    
2234    checkpoint54d_post
2235    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
2236    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
2237      leading to additional shift by 5 days each year of integration
2238       (i.e. leading to considerable offset over the years)
2239    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
2240    o start with no AB and no initial filtering (staggerTimeStep):
2241      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
2242    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
2243      (external loading & cpl import/export stay in forward_step.F)
2244    o update coupling interface to work with new staggerTimeStep
2245    o change MDSIO ptracers_pickup.
2246    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
2247    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
2248    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
2249    
2250    checkpoint54c_post
2251    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
2252      this affects (truncation error) output.txt of test-exp:
2253       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
2254    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
2255    o change Qnet to always be the net heat flux, (+upward).
2256      affects (truncation error) output of natl_box exp.: updated
2257    o define the max number of passive tracers in PTRACERS_SIZE.h
2258    o start to test mnc routinely in exp0
2259    o add sea-ice loading (sIceLoad) as a new forcing field.
2260    
2261    checkpoint54b_post
2262    o add testreport "-j JOBS" option for parallel builds (tested and pretty
2263       impressive on Altix and Opteron systems)
2264    o diagnostics can now write NetCDF files through the mnc package
2265    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
2266    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
2267    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
2268      affects (truncation error) output of lab_sea & natl_box exp.: updated
2269    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
2270    
2271    checkpoint54a_post
2272    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
2273    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
2274    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
2275    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
2276      + internal_wave (shift in writing cg2d_ini_res)
2277    checkpoint54a_pre
2278    
2279    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
2280      - modified verification/lab_sea and natl_box_adjoint accordingly
2281    
2282    checkpoint54
2283    checkpoint53g_post
2284    o prepare splitting of thermodynamics: store convect.counter in common block
2285    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
2286      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
2287    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
2288    o new parameter "nShapS": allow to treat differently S from T (nShapT)
2289    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
2290    o restore adjointability
2291    
2292    checkpoint53f_post
2293    o modifications that affect AIM experiment results (update output.txt):
2294      - no advection of S at top interface Nr (pkg/generic_advdiff)
2295      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
2296    o AIM pkg:
2297      - include stability function into surf.Flux derivative relative to Tsurf
2298      - calculate clear-sky radiation & surface temp. change (for diagnostics)
2299    
2300    checkpoint53e_post
2301    o merged cylindrical coord configuration
2302    o added rotating_tank experiment
2303    checkpoint53e_pre
2304    
2305    checkpoint53d_post
2306    o faulks upgraded: re-generate output.txt that have changed:
2307       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
2308    o Added Bryan and Lewis, 1979, vertical diffusivity profile
2309    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
2310    o added Sadourny discretization of Coriolis
2311      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
2312      - re-enabled use of omega3 (useAbsVorticity)
2313    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
2314      vector-invariant equations
2315      - note: does *NOT* yet use same variable visc. for no-slip BC's.
2316    o recoded the lateral boundary conditions for non-hydrostatic w, this time
2317      hopefully without new bugs
2318      - still to do: biharmonic friction for non-hydrostatic w
2319    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
2320    o regenerated output for global_ocean_ebm (using -ieee)
2321    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
2322      of mom_common/
2323      - simple re-arrangement of instructions within computing loop
2324    checkpoint53d_pre
2325    
2326    checkpoint53c_post
2327    o new version of coupler for AIM+thSIce and Ocean models
2328     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
2329     - land: change Evaporation of snow
2330     - aim with thSIce: fix bug in snow-precip.
2331    o changes to calc_gw.F
2332     - bug fix for w^2 term near the bottom boundary
2333     - (hopefully) improve the lateral slip boundary condtions for use with
2334        partial/looped cells
2335      - because the bug fix changes two verification experiments anyway (exp5
2336        and plume on slope), change the lateral boundary condition from half slip
2337        to the value of no_slip_sides
2338    o ebm package wasnt quite up to the parallel task. Fixed that.
2339    o Adjoint of EBM package + verification
2340      * TLM OK
2341      * ADM not sufficient accuracy yet (needs further testing)
2342    
2343    checkpoint53b_post
2344    o Commiting new energy balance model to repository
2345      * package is pkg/ebm
2346      * verif. is verification/global_ocean_ebm
2347      * references are in ebm_driver.F
2348    C      * X. Wang, P. Stone and J. Marotzke, 1999:
2349    C        Global thermohaline circulation. Part I:
2350    C        Sensitivity to atmospheric moisture transport.
2351    C        J. Climate 12(1), 71-82
2352    C      * X. Wang, P. Stone and J. Marotzke, 1999:
2353    C        Global thermohaline circulation. Part II:
2354    C        Sensitivity with interactive transport.
2355    C        J. Climate 12(1), 83-91
2356    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
2357    C        Destabilization of the thermohaline circulation
2358    C        by atmospheric eddy transports.
2359    C        J. Climate 7(12), 1870-1882
2360    o Will need long integration testing.
2361    checkpoint53b_pre
2362    
2363    o created pkg/mom_common in preparation for variable viscosity code
2364    o renamed and split ini_mnc_io
2365    o pkg/land: only liquid water can diffuse or run-off
2366    o AIM using land: soil wetness availability account for snow
2367    o added printMapIncludesZeros to EEPARMS namelist
2368    
2369    checkpoint53a_post
2370    o restore TAMC compatiility for exf_constants.h
2371      (no usage of _d in .h)
2372    o Additional storing in KPP in an attempt to fix
2373      TAMC problem with adjoint of KPP code.
2374      (no success...)
2375      Identical code works fine with TAF.
2376    o Fixed verification/natl_box_adjoint experiments.
2377      Initial conditions for Experiments 4 and 5 are now
2378      set to "SEAICE_initialHEFF=0", which is more reasonable,
2379      and hence gives results closer to that of Experiment 2.
2380      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
2381    
2382    checkpoint53
2383    o stable checkpoint with up to date adjoint
2384      TLM tests only run for 1st grdchk at the moment. Its unclear if
2385      this is a code problem or a problem with resetting code for g_
2386      variables that is being autogenerated wrong.
2387      Otherwise:
2388       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
2389       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
2390         are both still in chaos following their security messes.
2391    
2392    checkpoint52n_post
2393    o various build (mostly genmake2) changes including:
2394      - ability to build/run more easily within Cygwin and MacOS X
2395      - more complicated Makefiles with a stronger dependence on Gnu Make
2396    o pkg/seaice modifications
2397      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
2398        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
2399        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
2400      - changed proxy for geostrophic velocity and updated
2401        verification/lab_sea/results/* accordingly
2402      - removed ADI dynamic solver from pkg/seaice
2403      - replaced all occurrences of 1/CSTICE or 1/CSUICE
2404        they caused a segmentation fault under certain circumstances
2405      - removed unused field WATR
2406    o bug fix in exf-package:
2407      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
2408         now reflect that.
2409    o small fixes in the cal-package:
2410      - set reference date to first of January for the 'model'-calendar
2411      - failing of cal_CheckDate in cal_FullDate now actually results in a
2412        warning
2413    o small modifications in exf-package to increase flexibility:
2414      - change climtempfreeze from a constant to a runtime parameter that
2415        is specified in data.exf_clim (default = -1.9)
2416      - introduce runtime parameter windstressmax (default = 2.0) that is
2417        specified in data.exf
2418    o fix in pkg/thsice:
2419      - update Evap (Tsf changes) to be consistent with Latent heat flux
2420      - maintain snow precipitation unchanged (even if Tsf >=0).
2421     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
2422    
2423    checkpoint52m_post
2424    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
2425      this does not change any of the results, because myIter=0 in swfrac always
2426      lead to jwtype=2 (the default anyway), but the call makes little sense
2427      as a default
2428    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
2429    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
2430      atmospheric model (AIM) to use it ; add a "slab ocean" component.
2431    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
2432    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
2433    o extending useSingleCpuIO option to work with new exch2 I/O format
2434      - old-style, missing-tile I/O is still accessible by defining CPP
2435        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
2436    o monitor package can write to NetCDF files and/or STDOUT
2437    o fix re-definition bug in MNC_GRID_INIT_ALL()
2438    o doc/api_reference added
2439      - a framework for building an API Reference Manual using all
2440        the "protex" comments embedded in the code
2441      - see pkg/generic_advdiff, pkg/mnc for examples
2442    o MNC:
2443      - make myThid the last argument for all subroutines
2444      - new default for the grid files: NO halos
2445      - add useMNC and other run-time flags
2446      - separate per-file-group handling of the unlimited dimension
2447      - early initialization of MNC w/ flags read at the eeboot stage
2448        and lookup tables set in initialize_fixed
2449      - write all MNC output to a freshly-created directory
2450    o thermodynamics sea-ice (thsice) is now tested with testreport.
2451    o test exp. advect_cs: use the standard cs32 grid ; update output.
2452    o Added functionality to grdchk:
2453      pick global i,j,k position (or nearest wet) where to perform check.
2454    
2455    checkpoint52l_post
2456    o new land formulation:
2457      a) use ground enthalpy as prognostic variable to ensure exact
2458         energy conservation.
2459      b) account for water temperature and for latent heat of freezing
2460         in all processes (rain, run-off, ground storage)
2461      c) compute surface and ground temperature implicitly.
2462    o aim_v23 modification for new land model:
2463      a) Treat separately land / ocean / sea-ice surface fluxes
2464         to allow implicit computation of land & sea-ice surface temp.
2465      b) add snow precipitation.
2466    checkpoint52l_pre
2467    
2468    o fix problem (when 1 tile is empty) in min/max monitor.
2469    o fix bug in timeAve (u,vZetatave in common block)
2470    o no restoring terms under ice for pkg/seaice
2471    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
2472    o bug fix for pkg/seaice pickups
2473    o change MNC call locations and add coordinate attributes
2474    o mask vorticity at the corner ; affects global_ocean.cs output

2482    o fixed bug introduced in pkg/monitor
2483    o accuracy ctrlprec = 32 insuffient for gradient checks using
2484      averaged fields (I/O via cost_averages)
2485      -> use ctrl.h in active_file*.F to control I/O precision.
2486    o paramter list of CALL ADTHE_MAIN_LOOP
2487    o added initial do_the_model_io to ecco
2488    o set all ...Freq to zero after cost_final

2490    o MAIN and ECCO differentiability restored
2491    
2492    checkpoint52j_post
2493    o fix nchklev in tamc.h for global_ocean...
2494    o Bringing flow and store directives up-to-date
2495    o Really weird thing!
2496      call do_the_model_io from the_main_loop with parameters
2497      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
2498      TAF places a faulty re-call of initialise_varia
2499      after cost_final call which should not be there!
2500    checkpoint52j_pre
2501    
2502    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
2503      error messages
2504    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
2505    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating

2509      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
2510    o update AIM Equatorial Channel exp:
2511      use standard aim_v23 pkg and change the SST fields to be more realistic.
2512    o globalFile now works with exch2
2513    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
2514      mon_vort3.F to make exch2 friendly with >1 tile per cube face
2515    o limit timeave output for hi-res integrations

2520    checkpoint52i_pre
2521    
2522    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
2523      the old pkg/aim).
2524    
2525    checkpoint52h_pre
2526    o shortened offending lines in exch2_send_rx?.template
2527    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
2528    o genmake2: add build & execute test for NetCDF code
2529    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
2530      old grid files, moved CPP_EEMACROS.h to pkg/exch2
2531    o added useSingleCPUIO flag to monitor.F and mon_out.F
2532    o added temporary hack for sea-ice dynamics on the cube:
2533      metric terms are ignored and it is assumed that
2534      there is no sea-ice on cube faces 1, 2, 4, and 5.
2535    
2536    checkpoint52f_post
2537    o added exch2 cube routines to pkg/exch2
2538    o modified hs94.cs-32x32x5 to use it
2539    o added new grid files to hs94.cs-32x32x5
2540    checkpoint52f_pre
2541    
2542    checkpoint52e_post
2543    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
2544      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
2545    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
2546      to work with implicit vertical advection and AB ;
2547    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
2548    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
2549     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
2550    checkpoint52e_pre
2551    
2552    o fix bug in impldiff when Nr=1 or Nr=2.
2553    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
2554    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
2555    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
2556      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
2557    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
2558    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
2559    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
2560    
2561    checkpoint52d_post
2562    o re-tiled many expts to allow comparison in multi-processor mode
2563      - updated output accordingly
2564      - changed hs94.128x64x5 to use intial T from file rather than use the
2565        random number generator
2566    o add infrastructure in model routines for fizhi and gridalt packages
2567    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.

2569      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
2570      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
2571      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
2572        of surface winds for the cube
2573      (A verification experiment, based on global_ocean.cs32x15, but with
2574       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
2575       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
2576       complete with example surface forcing files and matlab scripts to look
2577       at the output and compare it with that of global_ocean.cs32x15.)
2578    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
2579       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
2580       to conform to the common rule.
2581    o check-in the first version of the coupler + interfaces for multi-components
2582       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
2583       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
2584       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
2585       - ocean and atmos. share the same horizontal grid (no interpolation).
2586       - exchanges between component and coupler is done in forward_step
2587    o new verification experiment, cpl_aim+ocn:
2588       coupled ocean - AIM atmosphere on cs32 grid.
2589    
2590    checkpoint52d_pre
2591    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
2592    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
2593    
2594    checkpoint52c_post
2595    o Fixing OPTIONS files for use of exf:
2596      - ALLOW_ECCO not needed
2597      - ECCO_CPPOPTIONS.h should not be included from
2598        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
2599        as has been the case in the past
2600      - All cal/exf related options are currently set in
2601        single header file. Should remain so until we
2602        agree on a consistent new policy.
2603    o Removed all CPP options for cal package.
2604      cal has no more CPP options.
2605    o modified STOREs in GAD_ADVECTION
2606    o corrected key comp. for passkey
2607    
2608    checkpoint52b_post
2609    o new version: "thsice" of thermodynamic sea-ice pkg:
2610     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
2611     - modify fluxes but do not change theta directly;
2612     - light cleaning of bulk_force pkg (still needed with thsice).
2613     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
2614       + output_thsice.txt to test thsice & bulk_force pkgs.
2615    o put back grid & coriolis monitor output.
2616    checkpoint52b_pre
2617    
2618    o call "do_the_model_io" at the beginning (=> dump initial state)
2619    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
2620    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
2621      (need info on NUMBER_OF_PTRACERS)
2622    o missing PTRACERS headers in some routines
2623    o default tamc.h in pkg/autodiff supposed to crash
2624      to ensure proper customization
2625    
2626    checkpoint52a_post
2627    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
2628      - moved surfaceTendencyTice from pkg/seaice to main code
2629      - subroutine FREEZE_SURFACE now limits only surface temperature
2630        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
2631        => new output.txt for global_ocean.cs32x15 & global_with_exf
2632      - keep the old version of FREEZE for backward compatibility;
2633        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
2634      - corresponding modifs for TAF directives
2635    o added surface flux output variables to TIMEAVE_STATVARS

2639      but no warning issued by TAF
2640    
2641    checkpoint52a_pre
2642    o some bug fixes for #undef REAL4_IS_SLOW
2643    
2644    checkpoint52 = ecco_c52_e35
2645    o after testing adjoints of checkpoint51u_post
2646    
2647    checkpoint51u_post
2648    o this is the post-merge tag of the ecco-branch
2649      (needs another clean checkout and re-testing)
2650    o various natl_box_adjoint configs and results
2651      but no input fields
2652    o obcs adjoint not yet merged!
2653    o adding ECCO global 1x1 and 2x2 degree configs
2654    o updated/extended some store directives for seaice
2655    o pkg/ecco now containes ecco-specific part of cost function
2656    o top level routines the_main_loop, forward_step
2657      supersede those in model/src/
2658      previous input data.cost now in data.ecco
2659      (new namelist ecco_cost_nml)
2660    o in ctrl/ cleaned some cross-dependencies and updated CPP options
2661    
2662    checkpoint51t_post
2663    o this is the pre-merge tag of the ecco-branch
2664    
2665    checkpoint51s_post
2666    o cleanup: removed various obsolete #define-s
2667    o pkg/grdchk
2668      - renamed 'ph-grd 3' to 'grad-res'
2669      - merged from ecco-branch
2670        (remaining bug fixes for obcs gradient checks)
2671      - additional high-precision output for testreport
2672        (grep for 'precision_grdchk_result')
2673    
2674    checkpoint51r_post
2675    o cleaned up or removed CPP_OPTIONS.h files
2676    o updated results for some of the tests to reflect the new
2677      optfiles (-ieee: -O0 instead of -O3)
2678    
2679    checkpoint51q_post
2680    o cd_code:
2681      - moved cd_scheme.F -> cd_code_scheme.F
2682      - separate read_checkpoint from cd_code_ini_vars.F
2683      - separated cd_code part from write_checkpoint
2684      - updated AD_SOURCE, generated .flow
2685      - added CD_CODE_VARS.h to the_main_loop

2687    o ctrl package totally restructured
2688      - pack/unpack now optional and decoupled from
2689        xx_/adxx_ I/O
2690      - ctrl_pack/unpack cleaned
2691        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
2692      - confined inclusion of AD_CONFIG.h to where necessary.
2693    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
2694    
2695    checkpoint51p_post
2696    o create initial cd_code package
2697      - WARNING: the initialization of fields within packages
2698        is broken because INI_FIELDS (where READ_CHECKPOINT is
2699        called) is called *before* PACKAGES_INIT_VARIABLES.
2700        This seems to be backwards since
2701        1) its important to initially zero the entire field including
2702           the "halo" region
2703        2) zeroing needs to be done *before* reading pickup info
2704           and the pickup call might or might not happen in any
2705           particular run
2706      - this needs an overhaul for R2
2707    o cleanup verification/*/code/GMREDI_OPTIONS.h
2708    o cleanup testreport
2709    
2710    checkpoint51o_post

2718    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
2719    o bug fix in find_alpha.F for MDJWF:
2720      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
2721        change rho -> rho-rhoConst
2722      - replace call find_rho to find_rhonum

2741      - moved surfaceTendencyTice from pkg/seaice to main code
2742      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
2743      - subroutine FREEZE now limits only surface temperature
2744        (this means new output.txt for global_ocean.90x40x15,
2745         global_ocean.cs32x15, and global_with_exf)
2746    o added surface flux output variables to TIMEAVE_STATVARS
2747    
2748    checkpoint51n_pre
2749    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F

2771    o enable to apply restoring on S & T only in a latitude band.
2772    o update output (external_forcing_surf modif. change truncation errors)
2773       global_ocean.cs32x15, global_ocean_pressure, lab_sea, natl_box
2774    
2775    checkpoint51k_post
2776    o change default to: useNHMTerms=.FALSE.
2777     - new output.txt for atmos. exp (NHMTerms were wrong but now turned off):

2872      - debLevA: standard
2873      - debLevB: equivalent to current debugMode=.TRUE.
2874    o introducing pathname variable mdsioLocalDir for mdsio
2875      that can be specified at runtime
2876      (relevant for cluster I/O to local disk)
2877    `
2878    >>>checkpoint51b_post
2879    adjoint of ptracers

2882    o alternative ctrl/cost with tr1 or ptracer
2883    o new comlev1_bibj_ptracers
2884    o new ptracers.flow
2885    o made ptracers_forcing same as external_forcing_s
2886    o added verification for adjoint with ptracers
2887      - adm. grdchk fail so far
2888      - tlm. grdchk OK
2889      - checked tapelev/comlev recomputations: OK
2890    <<<checkpoint51b_pre

2898    
2899    checkpoint51
2900    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
2901      - autodiff, ctrl, exf, grdchk, seaice
2902      kept separate packages
2903      - cost, ecco, obcs
2904    o updating verification/internal_wave, verification/lab_sea
2905      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
2906    
2907    checkpoint50i_post
2908    o Preparing next differentiable checkpoint and sync
2909      of MAIN vs. ecco-branch
2910      - 1st step: this one is differentiable
2911      - 2nd step: next(! not this) checkpoint will have updated packages
2912                  from ecco-branch)
2913    
2914    checkpoint50h_post
2915    o new package "land": provide surface BC for AIM.
2916    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
2917    o AIM: use true log-P extrapolation for near surface temp (= as in
2918        F.Molteni paper) ; update aim.5l_cs output.
2919    o New variable in PARM03 for more flexible pickups
2920    o somewhat cleaned package initialisation sequence for
2921      ctrl/ cost/ ecco/ in packages_... routines
2922    
2923    checkpoint50g_post
2924    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
2925      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
2926      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
2927        made the default because of faster convergence than ADI
2928    
2929    checkpoint50f_post
2930    o exf totally restructured
2931      - replaced all exf_set_ routines by one generic exf_set_gen.F
2932        and made sure it's still differentiable
2933      - split exf_getffields.F into new exf_bulkformulae.F
2934      - exf_inscal_/exf_outscal_ suffixes consistent with field names
2935      - updated adjoint/makefile and relevant verif. accordingly
2936

2945     o removed lots of single quotes from comments
2946    
2947    checkpoint50e_post
2948    o make KPP work with PTRACERS
2949     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
2950       nearly a copy of kpp_transport_s
2951     - there is no analogue to SurfaceTendencyS, so I have to use
2952       gPtr(of the surface layer) instead
2953    o add a new platform SunFire+mpi (SunFire 15000) to genmake
2954    checkpoint50e_pre
2955    
2956    checkpoint50d_post
2957    o change kpp output from multiple-record state files to single-record state
2958      files analogous to write_state.F
2959    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
2960      analogous to the cg2d-related output.
2961    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
2962      so that writing to internal file fn (with length 512) fails.
2963    checkpoint50d_pre
2964    
2965    checkpoint50c_post
2966    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
2967    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
2968    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
2969    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
2970    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
2971    
2972    checkpoint50c_pre
2973    Merging from release1_p13:
2974    o bug fix for pkg/seaice dynamic solver
2975    o Added SEAICE_initialHEFF to pkg/seaice
2976    
2977    checkpoint50b_post
2978    o store u*,v* in gU,V instead of in guNm1,gvNm1
2979    o in order to put the momForcing out of the Adams-Bashforth:
2980      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
2981      to timestep.F
2982    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
2983    o re-generate output for highly sensitive test-exp:
2984       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
2985    
2986    checkpoint50b_pre
2987    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
2988    o corrected CPP option mismatch in exf_Bulk... functions for case
2989      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
2990    
2991    checkpoint50a_post
2992    o Bug fix for merging between c50 and KPP.
2993      ikey was passed from thermodynamics to kpp_calc via
2994      common block rather than being recomputed in kpp_calc,
2995      in contradiction with new key itdkey.
2996      New key ikppkey created, and tamc.h headers updated.
2997    
2998    checkpoint50
2999    - 2nd step of merge with ecco-branch:
3000      merge changes in ecco-branch back into main trunk
3001    - bug fix in find_alpha
3002    - more storing in gmredi_calc_tensor.F, kpp_routines.F
3003    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
3004    - merged some sliced AD support routines
3005    
3006    checkpoint49
3007    merged from ecco-branch:
3008    o exf:
3009      - Enable initialisation of forcing fields to constant
3010        (runtime) values.
3011      - in exf_getffields.F
3012        Reduce i-/j-loop to interior domain, discarding overlaps.
3013        That also fixes wrong TAF-key computations for key_1, key_2
3014        with bulf formulae.
3015      - exf_init.F modify #ifdef for exf_init_evap
3016      - exf_getffieldrec.F, ctrl_getrec.F
3017        The following INT-usages are not safe:
3018          fldsecs  = int(fldsecs/fldperiod)*fldperiod
3019          fldcount = int(fldsecs/fldperiod) + 1
3020        and were modified.
3021    o autodiff: checkpoint_lev...
3022      - updated storing for bulk formulae (some arrays were missing)
3023      - added state for seaice package
3024      - synchronized with main branch
3025    o DIVA:
3026      Modif.s in
3027      - the_main_loop.F
3028      - the_model_main.F
3029      and added cost_final_restore.F cost_final_store.F
3030      o With these changes, it is possible to fully separate
3031        the first forward run to compute the cost function (mdthe_main_loop)
3032        and adjoint runs over individual DIVA intervals (adthe_main_loop)
3033        into separate model executions.
3034        This enables better tuning of DIVA to given queue sizes.
3035      o Loss of cost function value in consecutive DIVA runs is
3036        fixed by storing to 'costfinal' file.
3037      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
3038        beginning/end of adjoint integration is accounted for.
3039      The current changes apply to TAF-1.4.26.
3040      TAF has one remaining bug, requiring one manual change
3041      (see MITgcm manual).
3042    o cal: synchronized between MAIN and ecco-branch
3043    
3044    checkpoint48i_post
3045    o Changes to restore differentiability of code w.r.t. previous tag
3046      (mostly adding new routines to make list and replacing
3047      pressure by totPhiHyd).
3048    o Updated and merged grdchk package
3049      - has both ADM and TLM checks
3050      - works for single- and multi-proc.
3051      - output cleaned
3052      - worked successfully for parallel DIVA
3053    o genmake:
3054      - Adding -platform=SP4
3055      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
3056    o Modif. for DIVA:
3057      ctrl_unpack should not be called in intermediate DIVA interval.
3058      (similar thing would apply for active files such as
3059      tbar, sbar, psbar, which should not be reinitialised;
3060      only relevant for ecco-branch)
3061    
3062    checkpoint48h_post
3063    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
3064    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
3065    o Added SEAICE_initialHEFF to pkg/seaice
3066    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
3067    
3068    checkpoint48g_post
3069    --- EOS:
3070    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
3071      store total Potential in totPhyHyd for diagnostics & EOS.
3072    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
3073    --- Pressure/geopotential gradient:
3074    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
3075    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
3076      ( changes results of global_ocean_pressure )
3077    o NLFS + z-coord.: add eta*Rho' contribution.
3078    o accurate phiHyd when using interface-W at the middle between 2 centers
3079     ( changes results of ideal_2D_oce )
3080    o includes r* 2nd term in potential gradient.
3081    
3082    checkpoint48f_post
3083    Merging from release1_p12:
3084    o Modifications for using pkg/exf with pkg/seaice
3085      - improved description of the various forcing configurations

3088      - updated verification/global_with_exf/results/output.txt
3089    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
3090      (SBO) core products, including oceanic mass, center-of-mass,
3091      angular, and bottom pressure (see pkg/sbo/README.sbo).
3092    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
3093      to avoid negative values in shallow regions.
3094      - updated verification/natl_box/results/output.txt
3095      - updated verification/lab_sea/results/output.txt
3096    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
3097    o Added useSingleCpuIO option (see PARAMS.h).
3098    o Updated useSingleCpuIO option in mdsio_writefield.F to
3099      work with multi-field files, e.g., for single-file pickup.
3100    o pkg/seaice:
3101      - bug fix in growth.F: QNET for no shortwave case
3102      - added HeffFile for specifying initial sea-ice thickness
3103      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
3104    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
3105      kpp_transport_t.F, forward_step.F, and the_main_loop.F
3106    o pkg/seaice:
3107      - adjoint-friendly modifications
3108      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
3109    
3110    checkpoint48e_post
3111    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
3112    o dynamics: change definition of computational domain & adapt mom_fluxform
3113      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
3114    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
3115        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
3116        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
3117        global_ocean.90x40x15 global_with_exf global_ocean_pressure
3118        inverted_barometer solid-body.cs-32x32x1
3119      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
3120    
3121    checkpoint48d_post
3122    o in preparation for r*:
3123     a) use pre-computed gradient of hydrostatic potential:
3124        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
3125     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
3126        => affects results of glob_oce_pressure (different truncation error)  
3127      update output.txt of ideal_2D_oce & global_ocean_pressure
3128    
3129    checkpoint48d_pre
3130    o in preparation for r*:
3131      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
3132      pass the 2 comp. of the grad. as arguments to momentum S/R.
3133      but for the moment, only used if it does not change the results.
3134    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
3135    
3136    checkpoint48c_post
3137    Modifications in treatment of initial flux forcing controls
3138    to avoid extra storing of flux fields.
3139    
3140    checkpoint48c_pre
3141    o Added tidal_basin_2d experiment (currently 1D!)
3142    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
3143    
3144    checkpoint48b_post
3145    o r* coordinate added in #ifdef NONLIN_FRSURF block.
3146     (modification to pressure gradient not yet implemented)
3147    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
3148      (for U & V) that are used for vertical advection of momentum.
3149    
3150    checkpoint48a_post
3151    o In preparation for r*, use temp. array to compute vertical transport
3152       in flux-form momentum pkg. => change results of few test-exp.
3153      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
3154                        lab_sea, natl_box & plume_on_slope
3155    
3156    checkpoint48
3157    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
3158    
3159    checkpoint47j_post
3160    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
3161    o moved adexch from forward_step to addummy_in_stepping
3162    o added exch in ctrl_map_...
3163    o aveFreq.=0. at end of cost_final to avoid overwrite in
3164      reverse checkpointing loop
3165    o Yet more changes in gmredi:
3166      * adgmredi_calc_tensor
3167        avoiding all recomputation of gmredi_slope_limit
3168      * adgmredi_x/y/rtransport
3169        added flag for excessive storing to avoid recomp. of
3170        u/v/rtans, dTdx/y/z
3171        -> this is not really necessary and very memory-consuming
3172      * adgmredi_slope_psi:
3173        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
3174      * gmredi_slope_limit
3175        re-activated full calculation of taperfct for case 'ac02'
3176    o updating verification/ adjoints of carbon, global_ocean.90x40x15
3177    
3178    checkpoint47i_post
3179    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
3180    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
3181      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
3182    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
3183    o gmredi: fix few bugs.
3184    
3185    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
3186    This will be a good checkpoint to plug into the ecco-branch.
3187    o few modif.'s to get latest version adjointed
3188      (mainly kick out code in ini_linear_phisurf)
3189    o modif's to run adjoint with exactConserv
3190    o case GM_BOLUS_ADVEC should be cleaned
3191      S/R gmredi_slope_psi should be cleaned
3192    o verification/carbon now has exactConserv=.TRUE.
3193    
3194    checkpoint47g_post
3195    o time-average AIM output: becomes independent from statvars time-average
3196      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
3197    o After TAF bug fix:
3198      Tested adjoint of gmredi package.
3199      Tests were done with checkpoint47 rather than with latest
3200      checkpoint47f_post since the latter is broken for the adjoint
3201      verification/carbon/ contains both ADM and TLM gradient checks.
3202    Here they are, before they get changed/lost/stolen.
3203    Mostly modif.'s to fix numerical sensitivities.
3204    Gradient checks OK for
3205    - GM_taper_scheme:
3206      * clipping
3207      * ac02
3208      * linear
3209      * glw91
3210      * dm95
3211      * ldd97
3212    - GMREDI_OPTIONS:
3213      * GM_VISBECK_VARIABLE_K
3214      * GM_NON_UNITY_DIAGONAL
3215      * GM_EXTRA_DIAGONAL
3216      * GM_BOLUS_ADVEC
3217    in conjunction with data.gmredi parameters to be checked in
3218    in a few minutes under verification/carbon/code/
3219    
3220    checkpoint47f_post
3221    Merging from release1_p10:
3222    o modifications for using pkg/exf with pkg/seaice
3223      - pkg/seaice CPP options SEAICE_EXTERNAL_FORCING
3224        and SEAICE_EXTERNAL_FLUXES
3225      - pkg/exf CPP options EXF_READ_EVAP and
3226        EXF_NO_BULK_COMPUTATIONS
3227      - usage examples are Experiments 8 and 9 in
3228        verification/lab_sea/README
3229      - verification/lab_sea default experiment now uses
3230        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
3231    
3232    checkpoint47e_post
3233    o created a tag prior to creating a branch
3234    
3235    checkpoint47d_post
3236    o fixed bug in the oceanic pressure coordinates code: vertical viscosity
3237      at the bottom boundary had an erroneous half slip boundary condition
3238    o added bottom drag and no slip boundary condition capabilities to
3239      oceanic pressure coordinates code
3240    o added new verification experiment global_ocean_pressure, this experiment is
3241      also described in the tutorial section of the manual
3242    checkpoint47d_pre
3243    
3244    checkpoint47c_post
3245    o Added a verification experiment for a global cubed-sphere ocean run
3246      -  verification/global_ocean.cubed32x32x30
3247      -  uses pkg/therm_seaice and pkg/bulk_forcing
3248    
3249    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
3250    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
3251      when using P-coordinate; only implemented for atmospheric config.
3252    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
3253      NOTES: requires option NONLIN_FRSURF to be "#define".
3254    o update advect_xz/results/output.txt (left from checkpoint44g_post)
3255    
3256    checkpoint47b_post
3257    Merging from release1_p9:
3258    o pkg/seaice
3259      - removed GOTO's and added taf directives
3260      - double precision constants to reduce the g77 (Linux)
3261        to F77 (SGI) differences reported in release1_p8
3262    o tools/genmake
3263      - added SGI options
3264    o verification/testscript
3265      - updated to that of checkpoint47a_post
3266    o verification/global_ocean.90x40x15/input/eedata
3267      - modified for SGI f77 compatibility
3268    o verification/lab_sea
3269      - added description of sea-ice model
3270      - added missing matlab routines
3271      - added test of thermodynamics parallelization
3272    
3273    checkpoint47a_post
3274    o new pkg: aim_v23
3275     = F. Molteni atmos.physics (SPEEDY, ver23) adapted to MITgcm.
3276       for now, keep the same surface forcing as before.
3277     - Part-Cell implemented into AIM; check that Heat & Water are conserved
3278     - aim.5l_cs: use new aim pkg (run 10yr & get better results than before)
3279     - aim.5l_LatLon & aim.5l_Equatorial_Channel are still using old aim pkg
3280    o add diagnostic of surface correction term in monitor output
3281    
3282    o bulk_force and therm_seaice
3283    - Two packages:  bulk_force (Bulk forcing)
3284      and therm_seaice (thermodynamic_seaice) - adopted from LANL CICE.v2.0.2
3285    - Earlier integration from Stephaine Dutkiewicz
3286      and Patrick Heimbach.
3287    - Two ifdef statements for compile time,
3288       ALLOW_THERM_SEAICE and ALLOW_BULK_FORCE
3289    
3290    checkpoint47
3291    differentiable version of checkpoint46n_post
3292    o bug fix in quasihydrostaticterms
3293    o * "clean" adjoint code (in terms of extensive recomputations)
3294        can now be obtained for all GMREDI options (i.e. for
3295        - GM_VISBECK_VARIABLE_K
3296        - GM_NON_UNITY_DIAGONAL
3297        - GM_EXTRA_DIAGONAL
3298        - GM_BOLUS_ADVEC )
3299      * However, wrong gradient check problem remains unsolved.
3300      * New CPP options have been introduced for different
3301        tapering schemes
3302    o external_fields_load now part of differentiation list
3303    o pressure needs multiple storing;
3304      would be nice to have store_pressure at beginning or
3305      end of forward_step, e.g. by having phiHyd global (5-dim.)
3306      (NB: pressure is needed for certain cases in find_rho,
3307      which is also invoked through convective_adjustment).
3308    o recomputations in find_rho for cases
3309     'JMD95'/'UNESCO' or 'MDJWF' are OK.
3310    o #define ATMOSPHERIC_LOADING should be differentiable
3311    o ini_forcing shifted to begining of initialise_varia
3312    o Incorporating QNVS line search routines into MITgcm
3313      (this is separate code, and therefore not under pkg)
3314      lsopt/, optim/
3315    o Updated verification/carbon/
3316      - #define GM_VISBECK_VARIABLE_K
3317      - GM_taper_scheme    = 'ldd97'    
3318    
3319    checkpoint46n_post
3320    Merging from release1_p8:
3321    o verification/natl_box:
3322      updating new external_fields_load routine
3323    o New package: pkg/seaice
3324      Sea ice model by D. Menemenlis (JPL) and Jinlun Zhang (Seattle).
3325      The sea-ice code is based on Hibler (1979-1980).
3326      Two sea-ice dynamic solvers, ADI and LSR, are included.
3327      In addition to computing prognostic sea-ice variables and diagnosing
3328      the forcing/external data fields that drive the ocean model,
3329      SEAICE_MODEL also sets theta to the freezing point under sea-ice.
3330      The implied surface heat flux is then stored in variable
3331      surfaceTendencyTice, which is needed by KPP package (kpp_calc.F and
3332      kpp_transport_t.F) to diagnose surface buoyancy fluxes and for the
3333      non-local transport term.  Because this call precedes model
3334      thermodynamics, temperature under sea-ice may not be "exactly" at
3335      the freezing point by the time theta is dumped or time-averaged.
3336      N.B.: fairly large differences in accuracy occur across
3337            different platforms/compilers; comparison between
3338            g77 (Linux) and F77 (SGI Origin 2000/MIPSpro)
3339            generated output gives:
3340       T           S           U           V
3341      C D M    c        m  s        m  s        m  s        m  s

3345    
3346      Y Y Y Y  5  5  7  7  7  8 10  9  6  6  6  6  7  5  7  5  7 FAIL  lab_sea
3347    o GAD:
3348      - generated new common blocks to account for call of
3349        same gad routines with differing traceridentities
3350        (needed to modify tracerIdentity indices in GAD.h)
3351      - generated separate common blocks for case useCubedSphereExchange
3352        (Department of Futurology)
3353      - parameter lists to gmredi_?transport: added tracerIdentity
3354      - added new key indices to tamc.h
3355    o external_fields_load:
3356      - added this routine to TAF list
3357      - needed to make some common blocks global and additional storing
3358        along the same lines as exf package (checkpoint_lev?_directives.h)
3359    o exf:
3360      updated external forcing package
3361      - bug fixes carried over from ecco-branch
3362        (missing OBCS_OPTIONS.h in two routines)
3363      - enable easy to use "no forcing".
3364      - added exf I/O for atmospheric loading
3365      - added exf I/O for runoff data
3366      - transfered scaling between exf <-> MITgcm to exf namelist
3367    o Adding new verification experiment global_with_exf.
3368      This verification experiment is almost identical to the
3369      global_ocean.90x40x15 experiment, except that it uses
3370      the exf (and cal) package instead of the
3371      external_fields_load routine (cf README file).
3372    
3373    checkpoint46m_post
3374    o modified testscript to return -- when there are no lines of "%MON" output
3375    o added new flag "quasiHydrostatic" for QH mode
3376      and new routine quasihydrostaticterms()
3377    o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term)
3378      New routine: mom_u_coriolis_nh()
3379    o fixed sign of non-hydrostatic metric terms in u and v equations.
3380      Depend on correct sign of gravitySign.
3381    o added work.pc* to .cvsignore in aim directories using ifc
3382    o introduced flag for controllin non-hydrostatic metric terms
3383    o removed gravitySign from PARM04
3384    o switched to g77/ifc from pgf77 in aim experiments
3385    
3386    checkpoint46l_post
3387    o made convective adjustment work with pressure coordinates:
3388     - changed the direction of k-loop in convective_adjustment.F for the
3389       case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation)
3390     - adjusted the reference pressure k-index in convective_adjustment.F
3391     - adjusted the convection condition in convect.F (in analogy to
3392       calc_ivdc.F)
3393     - convective_adjustment no longer computes anything on the halos
3394     - removed the warnings about negative salinity from find_rho.F and
3395       find_alpha.F; instead the new routine look_for_neg_salinity, called
3396       at the beginning of find_rho, find_alpha, and find_beta, does a
3397       check of the entire slice, if CPP-option
3398       CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined
3399    checkpoint46l_pre
3400    
3401    checkpoint46k_post
3402    o fixed the verification/global_ocean.90x40x15 experiment:
3403     - new bathymetry (the world according to A., JMC, and M.)
3404     - new initial fields and forcing fields (*.bin files)
3405     - new POLY3.COEFFS (for the next release one should switch to a full
3406       equation of state: JMD95P or MDJWF)
3407     - fixed several errors and redundancies in the data file
3408     - experiment uses looped cells
3409     - added matlab directory with diagnostic scripts for plotting of output
3410    
3411    o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F:
3412     - read AIM physics parameters from a file (data.aimphys)
3413     - set defaults values = F.Molteni paper (Clim.Dyn., 2002)
3414    
3415    checkpoint46j_post
3416    o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH
3417    o move wVel computation at the end of the time step, in S/R integr_continuity
3418    o create specific S/R to exchange T,S before DYNAMICS (for stagger time step)
3419    o update timeave pkg for wVel diagnostic.
3420    checkpoint46j_pre
3421    
3422    checkpoint46i_post
3423    o Clean up AIM package (and keep the results unchanged):
3424      include CPP_OPTION and use IMPLICT NONE in all routines ;
3425      declare all the variables _RL ; use _d 0 for all numerical constants.
3426      use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 !
3427    
3428    checkpoint46h_post
3429    o cleaned up the use of rhoNil and rhoConst.
3430      - rhoNil should only appear in the LINEAR equation of state, everywhere
3431        else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst
3432        and the dynamical equations are all divided by rhoConst
3433    o introduced new parameter rhoConstFresh, a reference density of fresh
3434      water, to remove the fresh water flux's dependence on rhoNil. The default
3435      value is 999.8 kg/m^3
3436    o cleanup up external_forcing.F and external_forcing_surf.F
3437      - can now be used by both OCEANIC and OCEANICP
3438    checkpoint46h_pre
3439    
3440     Added code to convert surface volume flux (fresh water) into
3441     a mass flux when using P coordinates in the ocean (OCEANICP).
3442     Note: It assumes you have set rho0=rhoConst=density of fresh water.
3443    
3444    checkpoint46g_post
3445    o Include a new diagnostic variable phiHydLow for the ocean model
3446      - in z-coordinates, it is the bottom pressure anomaly
3447      - in p-coordinates, it is the sea surface elevation
3448      - in both cases, these variable have global drift, reflecting the mass
3449        drift in z-coordinates and the volume drift in p-coordinates
3450      - included time averaging for phiHydLow, be aware of the drift!
3451    o depth-dependent computation of Bo_surf for pressure coordinates
3452      in the ocean (buoyancyRelation='OCEANICP')
3453      - requires a new routine (FIND_RHO_SCALAR) to compute density with only
3454        Theta, Salinity, and Pressure in the parameter list. This routine is
3455        presently contained in find_rho.F. This routine does not give the
3456        correct density for 'POLY3', which would be a z-dependent reference
3457        density.
3458    o cleaned up find_rho
3459      - removed obsolete 'eqn' from the parameter list.
3460    o added two new verification experiments: gop and goz
3461      (4x4 degree global ocean, 15 layers in pressure and height coordinates)
3462    checkpoint46g_pre
3463    
3464    checkpoint46f_post
3465    o Enable tangent linear (forward mode) gradient checks:
3466      - extended active file handling to g_... files
3467      - added TANGENT_SIMULATION to theSimulationMode
3468      - extended grdchk package accordingly
3469    o added tangent linear setup in verification/carbon/code_ftl
3470    o added adjoint setup in verification/front_relax/code_ad
3471    
3472    checkpoint46e_post
3473    o Added new equation of state -> MDJWF
3474      - EOS of McDougall et al., 2002, JAOT, submitted
3475      - caveat: the equation of state is only valid for a smaller (more
3476        realistic?) range of values than JMD95P/Z and UNESCO
3477      - added masks to the calculation of pressure in store_pressure
3478      - added more check values for density in check_eos (ini_eos.F), some of
3479        the old check values are out of the range of the MDJWF-eos, so don't
3480        expect perfect matches for those
3481    checkpoint46e_pre
3482    
3483    checkpoint46d_post
3484    o fixed store_pressure to work with both buoyancy relation = 'OCEANIC' and
3485      'OCEANICP', also initialised field pressure correctly in ini_eos in the
3486      case of pressure coordinates. eosType='JMD95Z' in
3487      combination with buoyancyRelation='OCEANICP' now causes an error.
3488    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
3489      in find_alpha/beta.
3490    checkpoint46d_pre
3491    
3492    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
3493      so that JMD95Z and JMD95P give approptiate static stability in find_rho.
3494    
3495    checkpoint46c_post
3496    o Changes necessary for ocean in p-coordinates
3497     -  Added new buoyancy relation = 'OCEANICP'
3498     -  Added new parameters = gravitySign (this used to be contained inside
3499        the factor dRdZ which I added when we first switched to R coordinates).
3500     X GM/Redi is not compatible (yet)
3501     X bottom drag and no-slip need to be debugged.
3502    checkpoint46c_pre
3503    
3504    checkpoint46b_post
3505    o Added new equation of state -> JMD95Z and JMD95P
3506      - EOS of Jackett and McDougall, 1995, JAOT
3507      - moved all EOS parameters into EOS.h
3508      - new routines ini_eos.F, store_pressure.F
3509    o Added UNESCO EOS, but not recommended because it requires
3510      in-situ temperature (see JMD95)
3511    o Modified formatting for knudsen2.f in utils/knudsen2 and added
3512      unesco.f to be used with POLY3
3513    checkpoint46b_pre
3514    
3515    checkpoint46a_post
3516    o Added (atmospheric) pressure loading
3517      - new field in FFIELDS.h, etc...
3518      - new cpp flag ATMOSPHERIC_LOADING
3519    o Changed hFacC to _hFacC in calc_phi_hyd.F
3520    o Added SHORTWAVE_HEATING to some files for consistency
3521    checkpoint46a_pre
3522    
3523    checkpoint46
3524    further merges from release1_p5
3525    o new ctrl package
3526      - adopted from ECCO environment to enable optimization
3527      - added Eliassen Palm fluxes to controls
3528    o added Eliassen Palm flux controls to gradient check package
3529    o cost package
3530      - Compatible with new ctrl package
3531      - added Eliassen Palm cost hooks
3532      - modif's of existing cost functions
3533    o Adjoint-related bug fixes in kpp:
3534      - kpp_calc: sore of kpphbl avoids recomputation/call to S/R kppmix
3535      - kpp_routines: store of Rib avoids partial recomputation bug of TAF.
3536    o autodiff package
3537      - flow directives:
3538        + new for S/R do_the_model_io
3539        + enhanced for S/R checkpoint
3540        + new gmredi.flow
3541      - Introduced CPP option ALLOW_AUTODIFF_MONITOR to
3542        disable adcommon.h/g_common.h by default.
3543      - fixed problem for adjoint of global_max
3544    o modified verification/carbon/
3545    o New setup for adjoint of global_ocean
3546    o added hooks for Eliassen Palm fluxes (dynamics.F, ini_fields.F)
3547    o cleaned TAF keys iikey, idkey (dynamics.F, thermodynamics.F)
3548    o incorporated hooks for sponge layer code (external_forcing.F)
3549    
3550    checkpoint45d_post
3551    o import 2 fixes from release1_p5 (CG2D.h & packages_readparms.F)
3552    o use recip_dx*,recip_dy* instead of /dx*,/dy* in orlanski_E,W,N,S
3553      (affects plume_on_slope "cg2d" output)
3554    o add new parameter deltaTfreesurf for free-surface time stepping
3555    o exchange gT,gS when using staggerTimeStep & GM & Oly<4
3556    o NONLIN_FRSURF: rescale gNm1 to get a better conservation with A-B
3557    o change phiMin in exp1 (to agree with documentation)
3558    o add new flags:
3559     - T,S forcing inside/outside Adams-Bashforth
3560     - turn off temp,salt advection and/or forcing
3561     - for each tracer, define internal flag for multiDimAdvection & A-B
3562    o monitor: change definition of KE to check conservation of Energy
3563    
3564    checkpoint45c_post
3565    o Removed f90 comments ("!")
3566    o Modified initialisations to enable exf package for MITgcm
3567      (without invoking ECCO_PACKAGE).
3568    o modifications to gradient check package (Martin Losch)
3569      - enable centered differences
3570      - modified format of standard output
3571    
3572    checkpoint45b_post
3573    o cleaned exchange calls in cg2d
3574    o Included CPP option ALLOW_AUTODIFF_MONITOR in forward_step
3575    o included CPP option SINGLE_LAYER_MODE in thermodynamics
3576      to configure barotropic setup (Martin Losch)
3577    o moved some initialisations within bi,bj loop in dynamics
3578      (TAF flow dependency)
3579    o in initialise_varia, moved call packages_init_variables
3580      before convective_adjustment_init
3581      (corresponding adjustment of TAF tape initialisation).
3582    o in calc_diffusivity/calc_viscosity extended domain to full overlap.
3583    
3584    checkpoint45a_post
3585    o compute Rho over the whole domain (extend iMin,jMin indices)
3586    o specific exchange for X-slice domain (case Ny=1)
3587    o argument futureIter of S/R obcs_calc missing in exp4 & internal_wave /code
3588    o solve_for_pressure : set cg2d_x to zero where OBCS are applied
3589    
3590    checkpoint44h_post = checkpoint45
3591    o Fix to restore differentiability:
3592      place at which packages_init_variables is called in
3593      initialise_varia is crucial for reverse control flow.
3594    o modifications in GMRedi to enable stable adjoint
3595      (corresponding modif's in thermodynamics, dynamics)
3596    o added missing hook for sponge layer code in external_forcing
3597    o modified test cost functions
3598    o storing in gad_advection (plus removal of write(0,*)!
3599    o missing headers TR1.h added in convective_adjustment routines
3600    o errorMessageUnit set non-equal zero in eeboot
3601      (conflict on some platforms, e.g. IBM SP3)
3602    o modified carbon verif.
3603    
3604    checkpoint44h_pre
3605    o vertical grid option: allow to put the Interface at the middle between
3606      2 cell-centers ; replace delZ in pkg/kpp by drF.
3607    o GM Advective form: Tracers are advected using the residual transport (=
3608      Euler+GM-bolus); set param GM_AdvSeparate=T to return to previous form.
3609    
3610    checkpoint44g_post
3611    o fix surface correction term in multiDimAdvection (affects plume_on_slope
3612      results) ; ifdef missing in thermodynamics.F
3613    
3614    checkpoint44f_pre,checkpoint44f_post
3615    o added PTRACERS package
3616      This allows an arbitrary number of passive tracers to be integrated
3617      forward simultaneously with the dynamicaly model.
3618      + Implemented so far:
3619        - basic forward algorithm (time-stepping, advection, diffusion, convection)
3620        - I/O and checkpointing
3621        - GM/Redi  *but*  using the GM/Redi coefficient of Salt
3622      + Not implemented so far:
3623        - KPP
3624        - OBCS
3625      + No specific example supplied (yet) but global_ocean.90x40x15 has the
3626        necessary data.ptracer file. Simply use -enable=ptracers and uncomment
3627        line in data.pkg.
3628      + This package is disabled by default since it increases storage.
3629    
3630    
3631    o testscript: added -cleanup option
3632    o Shap_filt: a) new shap_filt S/R to use no-slip BC with S2 filter
3633                 b) enable to filter 2D fields.
3634    
3635    checkpoint44e_pre,post
3636    o re-wrote convective adjustment to use pre-calculated weights
3637      Affects: model/src/convective_adjustment.F, convective_adjustment_ini.F
3638      Adds:    model/src/convective_weights.F, convectively_mixtracer.F
3639      Original calls to convect() still in place.
3640    
3641    chkpt44d_pre,post
3642    o added missing EXCLUDE_MONITOR flags
3643    o changed "e" to "_d" in gmredi_slope_limit, gmredi_slope_psi
3644      (incompatible typ in MIN/MAX expressions caused problems
3645      on IBM SP3)
3646    o in genmake added variable MAKEDEPEND
3647      plus resetting for case SunOS
3648    o added timer_stats.c routine for IBM SP3
3649    o removed variables in dynamics
3650    !!! I forgot to create tag chkpt44d_pre !!!
3651    !!! But chkpt44d_pre = chkpt44c_post    !!!
3652    
3653    o real fresh water flux implemented with non-linear free-surface.

3725    o new package rw/
3726      Added method for dumping intermediate local arrays:
3727      mdsio_writetile - same as mdsio_writefield except works from inside
3728                        bi,bj loop
3729      mdsio_writelocal - same as mdsio_writetile except works for local
3730                         arrays
3731      write_local_r? - higher-level wrapper for mdsio_writelocal
3732      Controlled by diagFreq. Defaults to zero (ie. no dumps)
3733      Example given at end of mom_vecinv.F that dumps some local arrays.
3734    o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
3735      control flux-form versus vector invariant code.
3736      Switch is runtime flag vectorInvariantMomentum (defaults to false)
3737      or genmake -DISABLE ...
3738    o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
3739      (additional storing is now needed for case vecinv;
3740      currently nothing implemented to switch this storing off
3741      in case fluxform is used since no CPP flag available).
3742    
3743    checkpoint40pre7

3756    o bug fix in gmredi_slope_limit for ldd97
3757    
3758    checkpoint40pre5
3759    o proper initialization of Adams-Bashforth time stepping
3760      + uses forward step for very first step of model (iter=0)
3761    o re-generated *all* output since almost all output is modified by this
3762      change (sorry but we've been putting this one off for about 2 years)
3763      + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
3764        *not* regenerated since they are already out of date and I don't
3765        want to create the impression that they are suddenly working.
3766    o removed KAP stuff for DEC's
3767    o modified/added many .cvsignore files in */code and */input
3768    o added new expt "solid-body.cs-32x32x1"
3769      + this uses an alternative form of ini_curvilinear_grid.F which
3770        is not necessarily any better than the current one...
3771    
3772    checkpoint40pre4
3773    o added re-initialisations of utrans,vtrans,rtrans in
3774      calc_common_factors which are crucial for TAF.

3795       in addummy_in_stepping
3796     o Updated verification/vero/ (bug fixes in code/, correct pickups in input/)
3797     o Enabled "sliced" (xz-,yz-) exchanges, needed for obcs.
3798     o Included following packages:
3799       cal: calendar
3800       exf: external forcing
3801       ecco: essential routines to control use of cal, exf
3802             (NB: this is not the full ECCO environment)
3803     o disabled some packages by default in genmake
3804    
3805    checkpoint38
3806     o see notes_c37_adj.txt
3807     o corrected wrong layer index in external_forcing_t
3808     o replaced the_main_loop/forward_step by the_main_loop
3809     o removed forceoutput from write_state
3810       (replaced criteria for initial/final state)
3811     o added runtime flag for pre-C35 pickups: usePickupBeforeC35
3812    
3813    checkpoint37
3814     o mdsio.F routine split and packaged in pkg/mdsio
3815       (mdsio.F and mdsio_gl.F still exist in eesupp/src but are not
3816        used unless genmake -disable=mdsio)
3817     o allow a more precise surface-geopotential gradient for the atmosphere
3818       taking into account the change in space of Alpha (=1/rho) at the surface.
3819     o variable "etaN" (replace cg2d_x) is the surface R-anomaly [r unit]
3820       (ocean: sea surface height [m] / atmos: surface pressure anomaly [Pa])
3821     o Change units: Phi_Hydrostatic (=phiHyd), Phi_Surface(=cg2d_x) and
3822       Phi_NonHydrostatic (=cg3d_x), all have now the dimension of a potential
3823       [m2/s2] (pressure/rhoConst in the ocean ; Geo-Potential in the atmosphere).
3824     o Time-Average diagnostics defined as a pseudo package "timeave".
3825     o pickup files : old pickup (before c35) did not work with new code (c35
3826       and after) unless activating 2 commented lines in initialise-varia.
3827     o Non-Hydrostatic pickup file Pb fixed.
3828     o bug with Rigid-lid version (since c35) fixed.  
3829    
3830    checkpoint36
3831     o implement Crank-Nickelson barotropic time-stepping
3832     o recover Time-Average diagnostics
3833     o fix Pb in checkpoint (PR#19)
3834     o AIM become a standard package ; clean unused CPP_kees
3835    
3836    checkpoint35
3837     o subtantial rewrite of dynamics.f
3838     o allows staggered time-stepping
3839     o packaged obcs, aim (Atmospheric Physics), zonal_filt, shap_filt
3840     o added bottom drag (linear + quadratic)
3841    
3842    checkpoint34
3843     o Modified exchange routines for correct reverse simulation.
3844     o Added verification output to comply with bug fix in impldiff.F
3845       as of c33 (exp2, natl_box).

3847     o Corrected array boundaries in impldiff.F
3848     o Corrected array dimensions in gmredi.

3852    
3853    checkpoint33
3854     o Fixed bug in lower BC in impldiff.F
3855     o Fixed confusion about units of forcing arrays in FFIELDS.h
3856       namely Fu,Fv,Qnet,Qsw,EmPmR:
3857       - Removed verification/natl_box/code/external_fields_scale.F
3858         (did not differ from that in model/src)
3859       - Changed units of fu,fv,Qnet,Qsw,EmPmR back to proper units
3860         (see FFIELDS.h for description)
3861       - Scale fu,fv,Qnet,Qsw,EmPmR when used in external_forcing_surf.F,
3862         kpp_calc.F and kpp_transport_t.F
3863       - Removed model/src/external_fields_scale.F and calls to it
3864       - verification/natl_box uses flux data with "atmospheric" sign so
3865         a special version of external_fields_load.F is used to
3866         change the data as it's read in. This way, the arrays
3867         have the right units and signs at all times tha a user could
3868         possibly use them.
3869     o Corrected genmake to delete a temporary file during configuration
3870    
3871    checkpoint32
3872     o Scaling of forcing fields moved from external_forcing.F to
3873       external_fields_scale.F, called directly after loading fields.
3874     o Surface relaxation terms added to surface tendency fields in
3875       extra subroutine.
3876     o impldiff.F changed to avoid storing by TAMC of huge intermediate
3877       fields.
3878     o Changes in GMRedi to comply with packaging structure.
3879     o Modifications and bug fixes in KPP package.
3880     o Verification experiment for KPP added (verification/nat_box/)
3881    
3882    checkpoint31
3883     o Packages interface brought in line with defined standard
3884       -> new routines packages_...F
3885       -> changes in initialise_fixed.F, initialise_varia.F
3886       -> enables initialisation interface for ECCO package
3887     o Rescaling of external forcing fields immediately after read
3888       (removed from external_forcing.F)
3889       -> new: surface_fields_scale.F
3890       -> affects ini_foorcing.F, external_fields_load.F
3891     o Computation of surface tendencies before tendency updates.
3892       -> new: external_forcing_surf.F
3893     o Change of variable names useGMRedi, useKPP, useECCO
3894     o Further changes in dynamics.F, impldiff.F for TAMC
3895     o Tested for experiments 0, 2, 4.
3896       - not yet tested for GMRedi.
3897       - not yet tested for KPP.
3898    
3899    checkpoint30
3900     o Updates for OBCs
3901     o New experiment for test OBCs (internal_wave)

3903     o Updates for KPP: calculation of viscosity corrected, new variables
3904       kpp_dumpFreq and kpp_taveFreq
3905     o CPP'd calls to system routines for TARGET_CRAY_VECTOR (P.H.)
3906       and entry for T90 in genmake
3907    
3908    checkpoint29
3909     o packaged KPP and GM/Redi
3910    
3911    checkpoint28
3912     o Corrected initialization of hFacMin for difference vertical coordinates
3913     o Modified calculation of partial cell thickness to more robust algorithm
3914     o config_summary.F: replaced write_1D_... by write_0D_...
3915       read_write.F: added subroutines write_0D_...
3916     o routines calc_common_factors, calc_gs, calc_gt, calc_phi_hyd, find_rho:
3917       included some initialisations required for TAMC.
3918     o routine calc_isoslopes: modified sqrt computation to make it
3919       differentiable for zero argument.
3920     o routines dynamics, impldiff:
3921       included store directives and tape key computations required for TAMC.
3922     o ALL TAMC related changes are between ifdef ALLOW_AUTODIFF_TAMC
3923    
3924    checkpoint27
3925     o fixed calc_isoslopes() to so that cancellation of terms in tensor
3926       formulation works properly with variable resolution.
3927     o restructured the calling tree between the_model_main() and dynamics()
3928     o split initialise() into initialise_fixed() and initialise_varia()
3929     o introduced initialization file pSurfInitFile for free surface (cg2d_x)
3930       in new routine ini_psurf()
3931    
3932    checkpoint26
3933     o moved some #ifdef in optional routines to encompass everything
3934       except the argument declarations. This was using up some memory.
3935     o fixed macros like _ADT to work with both versions of Linux cpp
3936     o cleaned up some unused and uninitialized variables
3937       (helps when debugging with strict compile options)
3938     o split up CPP_EEOPTIONS.h into options and macros
3939       (macros are now in eesupp/inc/CPP_EEMACROS.h)
3940     o patch for 2 processor JAM mode
3941    
3942    checkpoint25
3943     o updates for OBCs and NH
3944     o dramatically reduced memory usage

3947     o added a diagnostic of convective index
3948     o moved call to calc_divg_hat() from dynamics() to solve_for_pressure()
3949       (this is was partly for OBCs and NH but also in anticipation of
3950        an explicit free-surface option)
3951     o initial state input files for U and V
3952    
3953    checkpoint24
3954     o Removed some spurious "REAL"s
3955     o Updated KPP to latest version from JPL

3960     o Multiple minor fixes (implicit none's, arguments to global_sum, etc.)
3961    
3962    checkpoint22
3963     o Made many small changes: implicit none, format(i5), etc...
3964     o Introduced KPP mixing scheme (compiles and runs but *not* tested)
3965    
3966    checkpoint21

3968     o Split-up mid-level I/O routines
3969     o Updated input data for experiments 0,1,2,4 and 5
3970     o Finally removed the genmake.* scripts (everyone seems happy with genmake)
3971    
3972    checkpoint20
3973     o Tidied up open-boundaries some more
3974     o Added non-hydrostatic code

3996    
3997    checkpoint16
3998     o Minor changes to exchange routines to support
3999       accumulation in reverse mode. Adjoint of an
4000       assignment is an addition.
4001     o Changes to support compilation by TAMC (LR(1)
4002       syntax) and by g77 under Linux ( 72 character
4003       limit ).
4004    
4005    checkpoint15
4006     Rewrote exchange routines to allow
4007     o General tile <-> tile connectivity.
4008     o TAMC reverse mode flag ( is this really needed? )

4012       communication method.
4013    
4014    checkpoint14

4020     of KGM time-averaging diagnostic errors. Also contains
4021     a double-gyre experiment setup as well as the baseline
4022     4 degree global template. The double gyre template is
4023     organised to allow it to be applied automatically to
4024     the baseline configuration.
4025    
4026    branch-point-rdot
4027     A few tidy-ups have been made bt the real point of this
4028     check-point (excuse the pun) is to allow a branch to be
4029     made for the purposes of adding the rDot alterations.
4030     I don't want to commit the rDot to the main-trunk until
4031     we've actually tested it...
4032
