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

1976    - introduced a useGCHEM runtime flag and applied it everywhere.    - introduced a useGCHEM runtime flag and applied it everywhere.
1977      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
1978        this flag is now only visible within GCHEM-pkg routines.
1979      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
1980        be replaced by a 3D array that is computed before thermodynamics; for
1981        this, the tracer ID iTracer had to be included into the parameter list
1982        of ptracers_forcing
1983      - set up forward_step to call gchem_forcing, that will replace
1984        gchem_forcing_int in ptracers_forcing
1985      - cleaning up
1986  o small cleaning of exch2: remove files that are also in eesupp/src  o small cleaning of exch2: remove files that are also in eesupp/src
