5      ==============================      ==============================
6    
7    checkpoint61
8    o autodiff
9      Change default for TAF usage by removing argument '-nonew_arg'
10      This changes TAF subroutine argument list (ordering of active var.)
11      Omission of this flag leads to incompatibility w.r.t. TAMC
12      To restore TAMC-compatibility, need following modifs:
13      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
14      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
15      Tested TAF version is 1.9.22
16      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
17    
18    checkpoint60
19    --->>> This is the last checkpoint for which generating the adjoint
20    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
21    --->>> by default.
22    --->>> Future checkpoints will ommit this flag by default.
23    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
24    o pkg/grdchk: Add gradient check to etan0 perturbations.
25    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
26    o pkg/autodiff: more flexibility in zeroadj.
27      model/src: modifying do_oceanic_phys.F accordingly.
28    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
29    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
30      special setup of gmredi for which the adjoint is stable
31      enough for parameter optimization.
32    o bridging the gap between eddy stress and GM.
33      -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
34          along with a change in CPP option (now ALLOW_EDDYPSI).
35      -> when using GM w/ GM_AdvForm:
36          The total eddy streamfunction (Psi = eddyPsi + K x Slope)
37          is applied either in the tracer Eq. or in momentum Eq.
38          depending on data.gmredi (intro. GM_InMomAsStress).
39      -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
40      The key modifications are in model/src/taueddy_external_forcing.F
41      pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F
42    
43    checkpoint59r
44    o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array
45      from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
46      fix option to read coriolis(@ cell-corner) from files with CS-grid.
47    o pkg/mnc: add some attributes to standard 1D-coordinate variables
48    o pkg/diagnostics: enforce missing_value attribute for scalar variables at
49      mass points, when using mnc for output
50      - add runtime parameter (missing_value, missing_value_int) to override
51        default (which is the value of getcon('UNDEF'))
52    o pkg/mnc: prepare mnc for the actual use of missing values with the
53      diagnostics package: small fix in mnc_cw_readwrite.template and more
54      initialisation of never used fields
55      - replace mnc_common.h and mnc_id_header.h with corresponding upper case
56      versions
57    o pkg/thsice/thsice_ini_vars.F added default initial values so that
58      thermodynamics sea ice solver does not blow up when some initial fields
59      are missing.
60    o move from external_forcing_surf.F to ini_forcing.F
61      the p-coord. hack consisting in using pLoad to set phi0surf ;
62      update output of tutorial_global_oce_in_p (affected @ truncation level).
63    o Freshen up a bit hs94.1x64x5, notably:
64      remove rotationPeriod and tRef=5*0. (adjoint only), and add
65      exactConserv=.TRUE.
66    o pkg/generic_advdiff:
67      change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only
68      applies to files where Temperature & Salinity 2nd Order moments are used.
69    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
70      this uses a dynamically allocated internal state data structure
71      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
72      and requires a fortran 90 compiler
73    
74    checkpoint59q
75    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
76       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
77    o Refresh tutorial_global_oce_biogeo, notably:
78      - change bathymetry (put back seamounts in ACC, use hFacs)
79      - change EOS (POLY3 --> JMD95Z)
80      - use Bryan-Lewis vertical diffusivity
81      - use multidimensional advection
82      - remove old virtual virtual in dic pkg, now done through ptracer pkg
83      - change a couple of parameters in dic pkg
84    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
85    o pkg/obcs: change default to OBCSfixTopo = .true.,
86      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
87      - replace "debugMode" with "debugLevel .GE. debLevB"
88    o implementation of TAF directives for gchem,cfc,dic
89    o remove "exp5" (replaced by tutorial_deep_convection).
90    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
91      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
92      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
93      --> changes results in exp4, seaice_obcs
94    o tutorial_deep_convection :
95      update the set-up and increase resolution and domain size ; start
96      from pseudo initial conditions = output at t=120mn in order to see
97      something happening when running testreport.
98    o pkg/seaice: add os7mp as an advection scheme
99                  add check for advection schemes
100                  add a flag for restoring T and S underneath sea ice
101    o pkg/my82: add netcdf-support and diagnostics
102    o thsice pkg:
103      - Now hsMax limits snow height by turning it into ice following
104        flooding scheme (and now conserving energy)
105      - Slight rewriting of the formula in thsice_calc_thick.F
106      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
107      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
108    
109    checkpoint59p
110    o gchem / dic / cfc :
111      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
112      - add new parameter files: "data.dic" & "data.cfc" ;
113      - various re-arrangement in initialisation & header file ;
114      - fix tutorial_global_oce_biogeo for multi-threaded test.
115    o pkg/dic: test for "pickup_dic" file when restarting ;
116      if no pickup-file, can restart with a re-initialised pH (same as it did
117      before) providing pickupStrictlyMatch is set to False.
118    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
119      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
120    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
121      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
122    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
123     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
124       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
125    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
126       scheme to use for vorticty-term ;
127     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
128       (with default selectVortScheme, return to original discretisation)
129     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
130    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
131    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
132      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
133      also fix diagnostics VISCAHW & VISCA4W.
134    
135    checkpoint59o
136    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
137    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
138      move a few statemens out the main loop into separate loops
139    o pkg/shelfice:
140      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
141        (kg/m^2/s), does not break tests, because in verification/isomip,
142        rhoConstFresh=rhoConst (by accident)
143      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
144      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
145        new file model/src/seawater.F, so that they are available for all pkgs.
146      - convert potential temperature into in-situ temperature. This changes the
147        isomip tests => update tests
148    o add a flag writePickupAtEnd (default=true) to be able to suppress
149      writing a pickup at the last timestep
150    o tools/mpack-1.6 :
151      - disable automake (not working) and autoconf (not needed).
152      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
153        also cleaner with much less compilation warnings.
154    o pkg/profiles:
155      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
156      (for "less than 32 characters name" compiler requirement)
157    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
158      conditions that have a different sampling frequency than S/T/U/V obcs
159    o pkg/diagnostics (stats-diags):
160      - fix global Min/Max in case 1 processor get only empty tiles
161    o genmake2: replace (4 times)
162         make genmake_tc_1.o >> genmake_warnings 2>&1
163      with
164         COMM="$CC $CFLAGS -c genmake_tc_1.c"
165         echo $COMM >> genmake_warnings
166         $COMM >> genmake_warnings 2>&1
167      to make genmake2 always see the value of CC as specified in the optfile.
168    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
169      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
170      - modify verification advect_cs test to test SOM-advection on CS-grid.
171    o pkg/ctrl:
172      - Rewrite of ctrl_map_ini_ecco.F,
173        introducing a generic routine (ctrl_map_ini_gen.F).
174      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
175    
176    checkpoint59n
177    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
178      number in dedicate array "hdiag":
179      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
180        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
181      - many small changes (integer format) for large number of diagnostics
182      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
183        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
184    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
185      usingSphericalGrid, this allows to define the rotated grid coordinates
186      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
187      geographical coordinates according to the inverse of the rotation defined
188      by the Euler angles, so that Coriolis parameter and online-interpolation by
189      exf works with the geographical coordinates on XC/YC/XG/YG.
190      Naturally, this feature does not work with all packages, so some
191      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
192      profiles), because there the coordinates are assumed to be regular
193      spherical grid coordinates.
194    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
195      - introduce isopycnal diffusion coefficient control.
196    o tools/adjoint_options:
197      - additional control vector components.
198    o pkg/mnc: have mnc create marginally meaning full coordinate variables
199      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
200    o pkg/mypackage:
201      - add example of read/write pickup for state-var ;
202      - add entry points to the main code for state-vars diags & write-pickup.
203    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
204      transitions for useExfYearlyFields
205      - add new subroutine that determines the file to read from for
206        use*YearlyFields = .TRUE. and .FALSE.
207      - add a verification experiment to global_with_exf that tests
208        useExfYearlyFields with USE_EXF_INTERPOLATION defined
209    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
210      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
211      subroutines (which could be generated from a template, because they are
212      almost identical), for now they are included in obcs_prescribe_read.F for
213      simplicity
214    o pkg/exf:
215      - add a little more diagnostic to exf_interp_read (in analogy to
216        mds_read_field, can be turned off with debugLevel < debugLevA=1)
217      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
218        ugly but fast by unrolling short inner loops, inserting a unroll=8
219        directive in routine lagran, and splitting a loop and making do while the
220        outermost loop (the latter requires the intoduction of index arrays)
221    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
222    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
223      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
224    o verification/seaice_obcs: updated for restart test and latest options
225    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
226      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
227      for now this is only available for the C-grid code and also within
228      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
229    
230    checkpoint59m
231    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
232      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
233    o gad_som : fix flux output (& diagnostics) to have same units as other  
234      advection scheme fluxes (was previously multiplied by deltaT).  
235    o added verification/seaice_obcs both to test seaice open boundaries
236      and to provide an example matlab scrpt for generating them
237    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
238    o pkg/salt_plume: clean up salt_plume_frac.F to
239      remove redundancy in PlumeMethod 1 and 4
240    o pkg/kpp: added saltplume diagnostics
241    o pkg/obcs and pkg/seaice:
242      - do not set uice and vice to zero when OB*icefile are unspecified
243      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
244      - moved seaice tracer obcs after call to seaice_growth
245    o pkg/salt_plume: added various options for salt plume depth
246      criterion and for vertical distribution of the salt
247    
248    checkpoint59l
249    o pkg/ptracers: new version of ptracers pickup:
250      read meta file and write only fields which are needed to restart.
251      ( same logic as main pickup file ; also using pickupStrictlyMatch )
252    o pkg/seaice:
253      - add timescale for melting due to warm mixed layer as a means of
254        setting SEAICE_availHeatFrac more conveniently
255      - add a CPP-flag/runtime parameter check for flooding algorithm
256      - reformulated availHeat in seaice_growth.F to be independent of AREA
257    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
258      unit changes
259    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
260    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
261      SX vector computer.
262    o pkg/seaice:
263      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
264        seaice forcing fields can now be read only through pkg/exf
265      - removed some unused halos
266    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
267    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
268      or U/VICE from U/VWIND before computing U/VSTRESS
269    
270    checkpoint59k
271    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
272      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
273    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
274      all experiments pass when compile with un-initialised var. checking option.
275    o added pkg/salt_plume
276    o script to test restart (for now, in MITgcm_contrib/jmc_script)
277    o pkg/seaice: new read/write pickup version.
278      read meta file and write only fields which are needed to restart.
279      ( same logic as main pickup file ; also using pickupStrictlyMatch )
280    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
281    o lab_sea.hb87: modify the domain & update output.hb87.txt :
282      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
283      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
284      process. Fixed here by closing the domain at the Northern boundary.
285    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
286    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
287      a set of consecutive levels in/from a 3-D array.
288    o pkg/ptracers:
289      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
290      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
291    
292    checkpoint59j
293    o in pkgs: dic, obcs, offline, rbcs:
294      standard way to compute coeff. for time interpolation between 2 time reccords
295      which retains full precision (& make results less dependent on compiler).
296      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
297    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
298      packages instead of reading ice cover and wind speed separately
299    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
300     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
301      to allow to compile customized code before the update)
302    o cleaning-up:
303      - fix CPP instruction syntax in pkg/obcs
304      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
305        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
306      - fix some threads issue in IO parts.
307    o pkg/dic:
308      - add tons of "_d 0" (--> much better testreports !)
309       and then update outputs of tutorial_global_oce_biogeo
310    o pkg/mom_fluxform:
311      add a special version of momentum advection intended to conserve momentum
312      next to a bathymetry step or a coastline edge. (default = off = #undef)
313    o new read/write pickup version:
314      - for now, only implemented for main (mdsio) pickup file.
315      - write out only what is needed to restart; merge pickup_nh , pickup_ph
316        and main pickup together.
317      - read meta file; read only what is needed to restart; stop if a field
318        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
319        if it make sense (even if the restart is not perfect).
320      - if no meta file, assume that pickup to read corresponds exactly to
321        a pickup that would currently be written.
322      - read pickup written in the old format (until checkpoint59i) if it
323        recognizes an old meta file (no field-list).
324      - add a meta file in exp. which starts from a pickup: 2 cases:
325        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
326         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
327        b) a meta file describing the content of the associated pickup file
328         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
329    o pkg/mdsio & pkg/rw:
330      - new routine to read a meta file ; new set of routine to read
331        Multiple-fields file (with meta file).
332    o added open boundary conditions capability for seaice
333        HSNOW, HSALT, UICE, and VICE
334    
335    checkpoint59i
336    o adjoint:
337      * fix multiDimAdvection adjoint
338        (partial recomputation problem by TAF for fVerT(:,:,kDown)
339        and comlev1 size definition (maxpass vs. max. number of tracers)
340      * verification/global_ocean.90x45x15 adjoint now tests
341        NLFS and multiDimAdvection using DST3 (=30)
342      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
343    o pkg/kpp: add "_d 0" to real constant (if missing);
344      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
345      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
346    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
347      for internal parameters related to restart process (formerly from PARAMS.h)
348      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
349    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
350      as argument. (only atm2d & obcs write_pickup have not yet been updated)
351    o pkg/monitor:
352      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
353      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
354      - account for deep Atmosphere factor and density factor (anelastic)
355    o added open boundary conditions capability for seaice HEFF and AREA
356    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
357      thermodynamics
358      - requires a little reorganization, which affects the testreport results
359        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
360        so that now the conservative form is tested
361      - add a few comments
362    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
363    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
364    o add new diagnostics to seaice: advective, diffusive fluxes (only for
365      multidim-advection, for scheme 2 they are not filled) and transports,
366      thermodynamic growth rates
367    o change units of EmPmR (inside the code, + within coupling interface)
368      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
369      Affects results @ truncation level (cg2d match) and update output of
370       experiments: lab_sea(6), global_ocean.90x40x15(10),
371      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
372      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
373      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
374      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
375    
376    checkpoint59h
377    o pkg/exf:
378      - improve vectorization by moving if-statement out of loops in
379        exf_mapfields, exf_radiation
380      - exf_bulkformulae.F: introduce 2D fields and vectorize code
381    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
382    o testreport:
383      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
384        monitor & update offline_exf_seaice exp. output.
385      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
386    o pkg/seaice:
387      - bug fix in the evp solver: boundary conditions were affected be
388        masking of zMax/zMin (changes results)
389      - minor bug fix in boundary conditions in seaice_calc_strainrates
390        (changes results for no_slip)
391      - seaice_lsr.F: make interpolation of eta dependent on boundaries
392      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
393      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
394        stress formulation and no-slip boundary conditions
395    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
396      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
397    o pkg/seaice: a first HSALT time stepping equation has been checked in
398    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
399      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
400      without requiring DO-IF statements
401    o pkg/thsice:
402      use continuous power-law function for partition of energy between lateral
403      melting/freezing and thinning/thickening ; old code using step function
404      still available with #undef THSICE_FRACEN_POWERLAW
405      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
406    o testreport: change AD testing : check against results/output_adm.txt
407      using same scripts as for forward test.
408    
409    checkpoint59g
410    o adjoint testing: in preparation for changing testreport:
411      - output format: cost and grad written on separated lines
412      - ad output results in directory "results" (instead of "results_ad")
413    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
414    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
415    o pkg/ecco: allow user defined cost function contributions
416    o testreport:
417      Allow to choose (per experiment) the list of tested output variables
418       and the main variable (used to issue a pass/FAIL ) ;
419      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
420      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
421      Also modify printing of summary:
422       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
423       b) echo the list of tested variables in the individual summary.txt of
424          each experiment.
425    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
426      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
427      (but still depend on the tile decompostion of the domain).
428    o pkg/seaice: change a discretization detail to make the B-grid code
429      "more symmetric". This change is likely to remove all "ridges/leads" that
430      where quasi-aligned with the grid in B-grid solutions. It may also be
431      the solution to the stress coupling issues with the B-grid.
432    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
433      remove .cvsignore from input dir. (since testreport no longer run here).
434    o pkg/thsice:
435     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
436     - fix reshaping of sea-ice just after advection:
437       melt all the ice only if ice-volume is too small.
438     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
439       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
440     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
441    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
442      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
443    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
444      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
445      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
446      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
447      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
448      -> update output.txt
449    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
450     this affects truncation error: -> update output.txt of exp:
451      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
452      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
453    
454    checkpoint59f
455    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
456    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
457      a bounded range (in forward mode)
458    o pkg/ecco, ctrl, autodiff and mom_common:
459     internal parameter controls, completements of implementations
460    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
461    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
462      (not seem any difference in testing results).
463    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
464       at face corners.
465    o pkg/generic_advdiff:
466     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
467      loop range indices for computing vertical advection tendency
468      and do the calculation in the interior only (no overlap) ;
469      for now, only implemented for SOM advection (to save CPU time).
470     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
471    o exch2 adjoint
472      First set of changes:
473      - add exch2 hand-written adjoint templates
474      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
475        This will require cleanup in pkg/autodiff/*.F
476        (changed routines currently kept separate in verif. code/)
477      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
478        that used to hide exch2 or cubed-sphere specific code
479        (commented via 'cph-exch2')
480    o pkg/seaice
481      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
482    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
483       output of global_ocean.cs32x15.thsice .
484    
485    checkpoint59e
486    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
487      for B-grid vector (not yet tested) and C-grid vector (<- only used
488      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
489    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
490      (#ifdef ALLOW_SALT_PLUME)
491    o gather_2d/scatter_2d: removed halo regions
492    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
493      scheme and the corresponding test case (under front_relax dir). For now,
494      only available with Skew-flux form and not yet tested in realistic set-up.
495      adjoint: store directives updated, but gradient checks deteriorated,
496      so maybe GM/Redi adjoint is now broken.
497    o seaice adjoint
498      * add AREA, HEFF, HSNOW as control variable
499        (should not change lab_sea results)
500      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
501    o pkg/seaice:
502      * added computation of saltFlux in seaice_growth;
503        For time being, sea ice salinity is assumed constant
504        contribution of snow flooding to freshening of sea ice is neglected.
505        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
506        defaults to 0.0 in order to maintain backward compatibility.
507        Typical values for SEAICE_salinity are 4 to 10 g/kg.
508      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
509      * added SEAICE_availHeatFrac, which specifies fraction of surface level
510        heat content used to melt or grow ice
511      * commented out cap of HICE: it helps keep ice thinner
512      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
513      * applied OBCS T/S mask to HEFFM sea ice mask
514    
515    checkpoint59d
516    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
517     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
518     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
519    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
520     and change default value of parameter "GM_Small_Number";
521     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
522       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
523       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
524    o pkg/ecco: cost function when applying pkg/smooth to controls
525    o pkg/ctrl: add forcingPrecond run time parameter
526    o pkg/seaice:
527     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
528     - fix bug in metric terms of u-equation in LSR solver (implicit part),
529       changes verification/lab_sea
530     - rearrange implicit part of u-equation in LSR solver to make it easier to
531       read, understand, and debug. This causes changes at the truncation level.
532     - fix (serious) bug in the boundary conditions (sign error in the implicit
533       part) of the LSR solver. Changes all LSR results.
534     - fixed problem with HSNOW initialization to avoid thick snow when AREA
535       is initilized with small values - does not change lab_sea results.
536     - added HsnowFile initialization capability
537    o pkg/smooth: addition to model/src and pkg/ctrl so allow
538     initialization of pkg/smooth and application to control vector
539    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
540    o dependencies: pkg/profiles requires pkg/cal
541    o pkg/profiles:
542     - added option ALLOW_PROFILES_GENERICGRID
543         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
544         that interpolation information (grid points and coefficients) is provided
545         within the netcdf input files.
546         -> sample matlab scripts can be found in MITgcm_contrib/gael
547         that allow you to prepare netcdf input files.
548     - also modified: cleaner include statements, cleaner error print statements,
549       cleaner stops when error, and more tests of the netcdf input files consistency.
550    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
551    o pkg/seaice:
552     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
553       requires a new routine: seaice_diagnostics_fill.F
554     - make sure that seaice does not move if not forced (pressure replacement
555       method, Hibler and Ip, 1995), changes results
556     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
557     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
558       It is turned off by default (=-1.), because it changes the results.
559     - make it possible to read AREA from a file, too.
560    
561    checkpoint59c
562    o add S/R and diagnostics for oceanic mixed-layer depth
563    o move GMRedi call after all vertical mixing schemes (including KPP)
564    o pkg/thsice:
565     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
566      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
567    o pkg/obcs:
568     - bug fix for balance code
569    o pkg/seaice:
570      - allow values of SEAICE_elasticParm > 1
571      - add new parameter SEAICE_evpTauRelax as an alternative
572        to SEAICE_elasticParm
573      - make lsr boundary conditions free slip (by default), changes result
574      - add code for no slip boundary conditions for lsr
575      - set minimum of zeta to zero (and not 4e8) (changes results)
576      - add a cap on AREA after advecting AREA if seaice_growth is not called
577    o change calculation of Visbeck K:
578      - no longer depend on tapering scheme; instead, compute slope (limited
579        by GM_maxSlope). this is equivalent to what was comuted before with
580        clipping or linear tappering.
581      - fix vertical averaging (wrong by 1/2 level)
582      - leave the old version (but will not be maintained) within
583        #ifdef OLD_VISBECK_CALC / #endif
584      - update output of exp. ideal_2D_oce
585    o change error catch in calc_r_star to improve vectorization
586    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
587      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
588    o adjoint:
589      Re-organized adjoint checkpointing according to Matt Mazloff
590      (but with modifs/completions/cleanups)
591      Storing is now bundled into large arrays to optimized I/O
592      (and second step in cleanup of the_main_loop)
593    
594    checkpoint59b
595    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
596      - export/import (between ocean & coupler) fields needed for ocean DIC.
597    o pkg/seaice:
598      - get rid of three more exchanges seaice_calc_viscosities (required
599        different loop boundaries in seaice_lsr and seaice_ocean_stress)
600      - bug fix in seaice_ocean_stress (update of lab_sea required)
601      - reduce loop boundaries to necessary minimum also in seaice_evp
602      - go back to the old way of computing deltaC/Z as the adjoint likes that
603        better
604    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
605      passive tracer to an Age Tracer) + update output.txt
606    o pkg/exf:
607      - implement A-grid / C-grid selection for wind-stress input files.
608      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
609      for now, in exf_bulk_largeyeager04.F only :
610      - change implementation for case where windspeed + 2. components wind-stress
611        are read-in. AND use rhoConstFresh to convert evap.
612    o pkg/seaice:
613      - use correct EXCH_UV for wind-forcing (on A-grid).
614      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
615        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
616    o pkg/exf:
617      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
618      EXF_INTERPOLATION:
619      - merge global_with_exf/code version of exf_interp_read.F
620        to the main code ;
621      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
622        reading the file ; Important: This options needs to be defined to recover
623        previous code.
624        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
625      - no longer loose real*8 precision along the way when using exf_iprec=64.
626    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
627      - change discretisation of evp-solver in order to avoid another exchange
628        (changes lab_sea) and clean up a little
629      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
630        help the adjoint (this also changes the results slightly)
631      - add a few "_d 0" where they had been missing in seaice_evp.F
632      - cleaning up: remove unused seaice_calc_rhs.F
633    o pkg/exf: some cleaning-up:
634      - change various "constants" into runtime parameters
635      - cleaned-up Large&Yeager04 routine which should eventually
636        replace exf_bulkformulae.F (changed names of S/R and CPP)
637        and merged various ALLOW_ATM_WIND options
638     only used with thsice pkg (in thsice_get_exf.F):
639      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
640        which are used when useStabilityFct_overIce=TRUE (= the default)
641      - change default values of ice & snow emissivity and scale downward LW
642        by ice & snow emissivity.
643    o pkg/thsice:
644     fix few little problems, in thsice_calc_thickn.F:
645      - growth vertically (and not laterally) if iceFrac == iceMaskMax
646      - melt only laterally if hIce < hThinIce (as the comments say)
647      and in thsice_extend.F:
648      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
649      - start to form ice as soon as the minimum ice-volume is reachable.
650     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
651      and cpl_aim+ocn
652    o pkg/kpp
653     - move computation of surface related input fields to KPP into a new
654       subroutine kpp_forcing_surf.F
655     - remove wrong (within bi,bj loops) EXCH calls.
656     - little cleaning (add argument myThid in last position, cvs header ...)
657     - for now, fix conservation problem by exchanging KPPviscAz (may not
658       be the best fix)
659    o pkg/seaice
660     - check for inconsistent evp parameter/cpp-flag combination
661     - remove leftover errIO flat for obsolete name list error handling
662    o OpenAD
663     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
664    
665    checkpoint59a
666    o pkg/seaice: some parameter clarifications and a little bit of clean up
667    o pkg/thsice: rename run-time parameters:
668       himin       -> hIceMin
669       himin0      -> hThinIce
670       hihig       -> hThickIce
671       i0          -> i0swFrac
672       transCoef   -> bMeltCoef
673       frac_energy -> fracMelting
674      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
675       with default values (for now) that do not change the results.
676      remove old version of thsice vars advection in pkg/seaice.
677    o in FFIELDS.h:
678      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
679      - make pLoad & sIceLoad always available (but still only used if
680         ATMOSPHERIC_LOADING is #define).
681    o pkg/kpp: replaced _KPP_RL with _RL
682    o bug fixes for vertical diffusivity computations when both KPP and
683        3D diffusivity arrays are used; pkg/kpp/kpp_calc_diff_s & _t.F
684        are no longer updating the vertical diffusivity array
685        (passed as argument) but are (re-) setting those arrays.
686    o pkg/seaice: fix bug in evp solver, while doing that
687      - change (improve?) discretization of stress computations for both
688        cgrid-lsr and evp solver
689      - add a new routine to compute strain rates
690      - the above changes lab_sea results
691      - add no slip conditions for evp solver (off by default), lsr-version
692        may follow
693      - fix exchange for shear at Z-points (does not change lab_sea)
694      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
695        (to force the user to pick a time step since there is not "safe" way
696        of choosing it)
697      - add principal stress diagnostics
698      - rearrange fields for evp a little to avoid having to call a: too many
699        exchanges and b: exchanges for stress trensor components which we do
700        not have.
701      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
702        of evp, complete rewrite for lsr case (latter is does not yet work
703        in all cases)
704    o pkg/kpp: add code to have mixing in shelf ice caverns
705      - add myThid to all kpp routines (long overdue)
706    
707    checkpoint59
708    o pkg/exf:
709      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
710        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
711      - move exf header files from lower_case.h to UPPER_CASE.h ;
712        add missing cvs Header & Name
713      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
714      - add namelist param. selectStressGridPosition, exf_monFreq
715      - retire many _CLIM routines, and remove data.exf_clim
716        + params moved to data.exf
717        + climsst, climsss now handled by exf_set_gen, i.e.
718          climss?period=0 refers to constant field,
719          climss?period=-12 to monthly forcing
720      - split up namelists in data.exf
721    o pkg/seaice:
722      - remove seaice_exch and seaice_exch_uv
723      - remove superfluous exchange of theta
724      - add myThid to seaice_budget_ocean/ice
725      - add new interface for atmospheric wind forcing (C-grid only)
726        + new routine
727        + two new field (taux, tauy for stress over ice)
728        + removed one global field (DAIRN) for C-grid case only
729    o pkg/thsise
730      - 2nd set of modifs for thsice adjoint in conjunction with exf
731    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
732    
733    checkpoint58y_post
734    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
735      vertical diffusivity, similar to that in MOM4; turned on using
736      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
737      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
738    o Added capability for 3D specification of background vertical diffusion
739      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
740      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
741      "data" file that contains the 3D vertical diffusivity coefficients.
742    o ice dynamics (pkg/seaice) with thsice thermodynamics:
743      - add code within pkg thsice to advect & diffuse sea-ice fields
744      similar to (and will replace) what has been added in  seaice_advdiff.F,
745      but: - conserving Mass, Heat & Salt.
746           - better when using non-linear advection scheme (not yet fully tested)
747           - can also be used in atmospheric set-up (for now, only the diffusion).
748    
749    checkpoint58x_post
750    o IO option for global-file compact format:
751      - add options when generating topology (utils/exch2/matlab-topology-generator)
752      - add I/O capability (pkg/mdsio).
753      - adapt utils/matlab/rdmds.m to read this format.
754      for now long-line format not yet supported by pkg/mdsio (& exch2).
755    o shelfice: add a few diagnostics
756    
757    checkpoint58w_post
758    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
759      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
760      (and replace horiVertRatio in NH code).
761      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
762                         and tutorial_plume_on_slope (sensitive to truncation)
763    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
764      directly to drive seaice model (C-grid only)
765    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
766     - reintroduce computation of wind from stress,
767     - compute tau (in exf_bulkformulae.F) from windstress averaged to
768       mass points to avoid tau = 0
769     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
770    o rdmnc.m: make it work with "global" files created with gluemnc
771    o rdmnc.m : some improvements in dealing with singleton dimension
772      (tested on all testreport mnc output files).
773    o genmake2: disable pkg/profiles if netcdf test fails.
774    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
775    o move call to cal_readparms up to make calendar parameters/variable available
776      to all packages
777    
778  checkpoint58v_post  checkpoint58v_post
779  o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get  o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
780    useDynP_inEos_Zc tested.    useDynP_inEos_Zc tested.
