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

1943      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
1944        this flag is now only visible within GCHEM-pkg routines.
1945      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
1946        be replaced by a 3D array that is computed before thermodynamics; for
1947        this, the tracer ID iTracer had to be included into the parameter list
1948        of ptracers_forcing
1949      - set up forward_step to call gchem_forcing, that will replace
1950        gchem_forcing_int in ptracers_forcing
1951      - cleaning up
1952  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
