4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/profiles:
8      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
9      (for "less than 32 characters name" compiler requirement)
10    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
11      conditions that have a different sampling frequency than S/T/U/V obcs
12    o pkg/diagnostics (stats-diags):
13      - fix global Min/Max in case 1 processor get only empty tiles
14    o genmake2: replace (4 times)
15         make genmake_tc_1.o >> genmake_warnings 2>&1
16      with
17         COMM="$CC $CFLAGS -c genmake_tc_1.c"
18         echo $COMM >> genmake_warnings
19         $COMM >> genmake_warnings 2>&1
20      to make genmake2 always see the value of CC as specified in the optfile.
21    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
22      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
23      - modify verification advect_cs test to test SOM-advection on CS-grid.
24    o pkg/ctrl:
25      - Rewrite of ctrl_map_ini_ecco.F,
26        introducing a generic routine (ctrl_map_ini_gen.F).
27      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
28    
29    checkpoint59n
30    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
31      number in dedicate array "hdiag":
32      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
33        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
34      - many small changes (integer format) for large number of diagnostics
35      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
36        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
37    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
38      usingSphericalGrid, this allows to define the rotated grid coordinates
39      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
40      geographical coordinates according to the inverse of the rotation defined
41      by the Euler angles, so that Coriolis parameter and online-interpolation by
42      exf works with the geographical coordinates on XC/YC/XG/YG.
43      Naturally, this feature does not work with all packages, so some
44      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
45      profiles), because there the coordinates are assumed to be regular
46      spherical grid coordinates.
47    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
48      - introduce isopycnal diffusion coefficient control.
49    o tools/adjoint_options:
50      - additional control vector components.
51    o pkg/mnc: have mnc create marginally meaning full coordinate variables
52      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
53    o pkg/mypackage:
54      - add example of read/write pickup for state-var ;
55      - add entry points to the main code for state-vars diags & write-pickup.
56    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
57      transitions for useExfYearlyFields
58      - add new subroutine that determines the file to read from for
59        use*YearlyFields = .TRUE. and .FALSE.
60      - add a verification experiment to global_with_exf that tests
61        useExfYearlyFields with USE_EXF_INTERPOLATION defined
62    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
63      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
64      subroutines (which could be generated from a template, because they are
65      almost identical), for now they are included in obcs_prescribe_read.F for
66      simplicity
67    o pkg/exf:
68      - add a little more diagnostic to exf_interp_read (in analogy to
69        mds_read_field, can be turned off with debugLevel < debugLevA=1)
70      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
71        ugly but fast by unrolling short inner loops, inserting a unroll=8
72        directive in routine lagran, and splitting a loop and making do while the
73        outermost loop (the latter requires the intoduction of index arrays)
74    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
75    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
76      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
77    o verification/seaice_obcs: updated for restart test and latest options
78    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
79      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
80      for now this is only available for the C-grid code and also within
81      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
82    
83    checkpoint59m
84    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
85      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
86    o gad_som : fix flux output (& diagnostics) to have same units as other  
87      advection scheme fluxes (was previously multiplied by deltaT).  
88    o added verification/seaice_obcs both to test seaice open boundaries
89      and to provide an example matlab scrpt for generating them
90    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
91    o pkg/salt_plume: clean up salt_plume_frac.F to
92      remove redundancy in PlumeMethod 1 and 4
93    o pkg/kpp: added saltplume diagnostics
94    o pkg/obcs and pkg/seaice:
95      - do not set uice and vice to zero when OB*icefile are unspecified
96      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
97      - moved seaice tracer obcs after call to seaice_growth
98    o pkg/salt_plume: added various options for salt plume depth
99      criterion and for vertical distribution of the salt
100    
101    checkpoint59l
102    o pkg/ptracers: new version of ptracers pickup:
103      read meta file and write only fields which are needed to restart.
104      ( same logic as main pickup file ; also using pickupStrictlyMatch )
105    o pkg/seaice:
106      - add timescale for melting due to warm mixed layer as a means of
107        setting SEAICE_availHeatFrac more conveniently
108      - add a CPP-flag/runtime parameter check for flooding algorithm
109      - reformulated availHeat in seaice_growth.F to be independent of AREA
110    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
111      unit changes
112    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
113    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
114      SX vector computer.
115    o pkg/seaice:
116      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
117        seaice forcing fields can now be read only through pkg/exf
118      - removed some unused halos
119    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
120    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
121      or U/VICE from U/VWIND before computing U/VSTRESS
122    
123    checkpoint59k
124    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
125      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
126    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
127      all experiments pass when compile with un-initialised var. checking option.
128    o added pkg/salt_plume
129    o script to test restart (for now, in MITgcm_contrib/jmc_script)
130    o pkg/seaice: new read/write pickup version.
131      read meta file and write only fields which are needed to restart.
132      ( same logic as main pickup file ; also using pickupStrictlyMatch )
133    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
134    o lab_sea.hb87: modify the domain & update output.hb87.txt :
135      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
136      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
137      process. Fixed here by closing the domain at the Northern boundary.
138    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
139    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
140      a set of consecutive levels in/from a 3-D array.
141    o pkg/ptracers:
142      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
143      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
144    
145    checkpoint59j
146    o in pkgs: dic, obcs, offline, rbcs:
147      standard way to compute coeff. for time interpolation between 2 time reccords
148      which retains full precision (& make results less dependent on compiler).
149      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
150    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
151      packages instead of reading ice cover and wind speed separately
152    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
153     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
154      to allow to compile customized code before the update)
155    o cleaning-up:
156      - fix CPP instruction syntax in pkg/obcs
157      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
158        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
159      - fix some threads issue in IO parts.
160    o pkg/dic:
161      - add tons of "_d 0" (--> much better testreports !)
162       and then update outputs of tutorial_global_oce_biogeo
163    o pkg/mom_fluxform:
164      add a special version of momentum advection intended to conserve momentum
165      next to a bathymetry step or a coastline edge. (default = off = #undef)
166    o new read/write pickup version:
167      - for now, only implemented for main (mdsio) pickup file.
168      - write out only what is needed to restart; merge pickup_nh , pickup_ph
169        and main pickup together.
170      - read meta file; read only what is needed to restart; stop if a field
171        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
172        if it make sense (even if the restart is not perfect).
173      - if no meta file, assume that pickup to read corresponds exactly to
174        a pickup that would currently be written.
175      - read pickup written in the old format (until checkpoint59i) if it
176        recognizes an old meta file (no field-list).
177      - add a meta file in exp. which starts from a pickup: 2 cases:
178        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
179         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
180        b) a meta file describing the content of the associated pickup file
181         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
182    o pkg/mdsio & pkg/rw:
183      - new routine to read a meta file ; new set of routine to read
184        Multiple-fields file (with meta file).
185    o added open boundary conditions capability for seaice
186        HSNOW, HSALT, UICE, and VICE
187    
188    checkpoint59i
189    o adjoint:
190      * fix multiDimAdvection adjoint
191        (partial recomputation problem by TAF for fVerT(:,:,kDown)
192        and comlev1 size definition (maxpass vs. max. number of tracers)
193      * verification/global_ocean.90x45x15 adjoint now tests
194        NLFS and multiDimAdvection using DST3 (=30)
195      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
196    o pkg/kpp: add "_d 0" to real constant (if missing);
197      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
198      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
199    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
200      for internal parameters related to restart process (formerly from PARAMS.h)
201      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
202    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
203      as argument. (only atm2d & obcs write_pickup have not yet been updated)
204    o pkg/monitor:
205      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
206      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
207      - account for deep Atmosphere factor and density factor (anelastic)
208    o added open boundary conditions capability for seaice HEFF and AREA
209    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
210      thermodynamics
211      - requires a little reorganization, which affects the testreport results
212        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
213        so that now the conservative form is tested
214      - add a few comments
215    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
216    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
217    o add new diagnostics to seaice: advective, diffusive fluxes (only for
218      multidim-advection, for scheme 2 they are not filled) and transports,
219      thermodynamic growth rates
220    o change units of EmPmR (inside the code, + within coupling interface)
221      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
222      Affects results @ truncation level (cg2d match) and update output of
223       experiments: lab_sea(6), global_ocean.90x40x15(10),
224      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
225      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
226      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
227      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
228    
229    checkpoint59h
230    o pkg/exf:
231      - improve vectorization by moving if-statement out of loops in
232        exf_mapfields, exf_radiation
233      - exf_bulkformulae.F: introduce 2D fields and vectorize code
234    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
235    o testreport:
236      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
237        monitor & update offline_exf_seaice exp. output.
238      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
239    o pkg/seaice:
240      - bug fix in the evp solver: boundary conditions were affected be
241        masking of zMax/zMin (changes results)
242      - minor bug fix in boundary conditions in seaice_calc_strainrates
243        (changes results for no_slip)
244      - seaice_lsr.F: make interpolation of eta dependent on boundaries
245      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
246      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
247        stress formulation and no-slip boundary conditions
248    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
249      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
250    o pkg/seaice: a first HSALT time stepping equation has been checked in
251    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
252      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
253      without requiring DO-IF statements
254    o pkg/thsice:
255      use continuous power-law function for partition of energy between lateral
256      melting/freezing and thinning/thickening ; old code using step function
257      still available with #undef THSICE_FRACEN_POWERLAW
258      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
259    o testreport: change AD testing : check against results/output_adm.txt
260      using same scripts as for forward test.
261    
262    checkpoint59g
263    o adjoint testing: in preparation for changing testreport:
264      - output format: cost and grad written on separated lines
265      - ad output results in directory "results" (instead of "results_ad")
266    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
267    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
268    o pkg/ecco: allow user defined cost function contributions
269    o testreport:
270      Allow to choose (per experiment) the list of tested output variables
271       and the main variable (used to issue a pass/FAIL ) ;
272      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
273      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
274      Also modify printing of summary:
275       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
276       b) echo the list of tested variables in the individual summary.txt of
277          each experiment.
278    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
279      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
280      (but still depend on the tile decompostion of the domain).
281    o pkg/seaice: change a discretization detail to make the B-grid code
282      "more symmetric". This change is likely to remove all "ridges/leads" that
283      where quasi-aligned with the grid in B-grid solutions. It may also be
284      the solution to the stress coupling issues with the B-grid.
285    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
286      remove .cvsignore from input dir. (since testreport no longer run here).
287    o pkg/thsice:
288     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
289     - fix reshaping of sea-ice just after advection:
290       melt all the ice only if ice-volume is too small.
291     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
292       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
293     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
294    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
295      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
296    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
297      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
298      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
299      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
300      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
301      -> update output.txt
302    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
303     this affects truncation error: -> update output.txt of exp:
304      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
305      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
306    
307    checkpoint59f
308    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
309    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
310      a bounded range (in forward mode)
311    o pkg/ecco, ctrl, autodiff and mom_common:
312     internal parameter controls, completements of implementations
313    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
314    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
315      (not seem any difference in testing results).
316    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
317       at face corners.
318    o pkg/generic_advdiff:
319     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
320      loop range indices for computing vertical advection tendency
321      and do the calculation in the interior only (no overlap) ;
322      for now, only implemented for SOM advection (to save CPU time).
323     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
324    o exch2 adjoint
325      First set of changes:
326      - add exch2 hand-written adjoint templates
327      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
328        This will require cleanup in pkg/autodiff/*.F
329        (changed routines currently kept separate in verif. code/)
330      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
331        that used to hide exch2 or cubed-sphere specific code
332        (commented via 'cph-exch2')
333    o pkg/seaice
334      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
335    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
336       output of global_ocean.cs32x15.thsice .
337    
338    checkpoint59e
339    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
340      for B-grid vector (not yet tested) and C-grid vector (<- only used
341      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
342    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
343      (#ifdef ALLOW_SALT_PLUME)
344    o gather_2d/scatter_2d: removed halo regions
345    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
346      scheme and the corresponding test case (under front_relax dir). For now,
347      only available with Skew-flux form and not yet tested in realistic set-up.
348      adjoint: store directives updated, but gradient checks deteriorated,
349      so maybe GM/Redi adjoint is now broken.
350    o seaice adjoint
351      * add AREA, HEFF, HSNOW as control variable
352        (should not change lab_sea results)
353      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
354    o pkg/seaice:
355      * added computation of saltFlux in seaice_growth;
356        For time being, sea ice salinity is assumed constant
357        contribution of snow flooding to freshening of sea ice is neglected.
358        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
359        defaults to 0.0 in order to maintain backward compatibility.
360        Typical values for SEAICE_salinity are 4 to 10 g/kg.
361      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
362      * added SEAICE_availHeatFrac, which specifies fraction of surface level
363        heat content used to melt or grow ice
364      * commented out cap of HICE: it helps keep ice thinner
365      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
366      * applied OBCS T/S mask to HEFFM sea ice mask
367    
368    checkpoint59d
369    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
370     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
371     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
372    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
373     and change default value of parameter "GM_Small_Number";
374     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
375       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
376       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
377    o pkg/ecco: cost function when applying pkg/smooth to controls
378    o pkg/ctrl: add forcingPrecond run time parameter
379    o pkg/seaice:
380     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
381     - fix bug in metric terms of u-equation in LSR solver (implicit part),
382       changes verification/lab_sea
383     - rearrange implicit part of u-equation in LSR solver to make it easier to
384       read, understand, and debug. This causes changes at the truncation level.
385     - fix (serious) bug in the boundary conditions (sign error in the implicit
386       part) of the LSR solver. Changes all LSR results.
387     - fixed problem with HSNOW initialization to avoid thick snow when AREA
388       is initilized with small values - does not change lab_sea results.
389     - added HsnowFile initialization capability
390    o pkg/smooth: addition to model/src and pkg/ctrl so allow
391     initialization of pkg/smooth and application to control vector
392    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
393    o dependencies: pkg/profiles requires pkg/cal
394    o pkg/profiles:
395     - added option ALLOW_PROFILES_GENERICGRID
396         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
397         that interpolation information (grid points and coefficients) is provided
398         within the netcdf input files.
399         -> sample matlab scripts can be found in MITgcm_contrib/gael
400         that allow you to prepare netcdf input files.
401     - also modified: cleaner include statements, cleaner error print statements,
402       cleaner stops when error, and more tests of the netcdf input files consistency.
403    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
404    o pkg/seaice:
405     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
406       requires a new routine: seaice_diagnostics_fill.F
407     - make sure that seaice does not move if not forced (pressure replacement
408       method, Hibler and Ip, 1995), changes results
409     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
410     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
411       It is turned off by default (=-1.), because it changes the results.
412     - make it possible to read AREA from a file, too.
413    
414    checkpoint59c
415    o add S/R and diagnostics for oceanic mixed-layer depth
416    o move GMRedi call after all vertical mixing schemes (including KPP)
417    o pkg/thsice:
418     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
419      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
420    o pkg/obcs:
421     - bug fix for balance code
422    o pkg/seaice:
423      - allow values of SEAICE_elasticParm > 1
424      - add new parameter SEAICE_evpTauRelax as an alternative
425        to SEAICE_elasticParm
426      - make lsr boundary conditions free slip (by default), changes result
427      - add code for no slip boundary conditions for lsr
428      - set minimum of zeta to zero (and not 4e8) (changes results)
429      - add a cap on AREA after advecting AREA if seaice_growth is not called
430    o change calculation of Visbeck K:
431      - no longer depend on tapering scheme; instead, compute slope (limited
432        by GM_maxSlope). this is equivalent to what was comuted before with
433        clipping or linear tappering.
434      - fix vertical averaging (wrong by 1/2 level)
435      - leave the old version (but will not be maintained) within
436        #ifdef OLD_VISBECK_CALC / #endif
437      - update output of exp. ideal_2D_oce
438    o change error catch in calc_r_star to improve vectorization
439    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
440      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
441    o adjoint:
442      Re-organized adjoint checkpointing according to Matt Mazloff
443      (but with modifs/completions/cleanups)
444      Storing is now bundled into large arrays to optimized I/O
445      (and second step in cleanup of the_main_loop)
446    
447    checkpoint59b
448    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
449      - export/import (between ocean & coupler) fields needed for ocean DIC.
450    o pkg/seaice:
451      - get rid of three more exchanges seaice_calc_viscosities (required
452        different loop boundaries in seaice_lsr and seaice_ocean_stress)
453      - bug fix in seaice_ocean_stress (update of lab_sea required)
454      - reduce loop boundaries to necessary minimum also in seaice_evp
455      - go back to the old way of computing deltaC/Z as the adjoint likes that
456        better
457    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
458      passive tracer to an Age Tracer) + update output.txt
459    o pkg/exf:
460      - implement A-grid / C-grid selection for wind-stress input files.
461      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
462      for now, in exf_bulk_largeyeager04.F only :
463      - change implementation for case where windspeed + 2. components wind-stress
464        are read-in. AND use rhoConstFresh to convert evap.
465    o pkg/seaice:
466      - use correct EXCH_UV for wind-forcing (on A-grid).
467      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
468        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
469    o pkg/exf:
470      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
471      EXF_INTERPOLATION:
472      - merge global_with_exf/code version of exf_interp_read.F
473        to the main code ;
474      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
475        reading the file ; Important: This options needs to be defined to recover
476        previous code.
477        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
478      - no longer loose real*8 precision along the way when using exf_iprec=64.
479    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
480      - change discretisation of evp-solver in order to avoid another exchange
481        (changes lab_sea) and clean up a little
482      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
483        help the adjoint (this also changes the results slightly)
484      - add a few "_d 0" where they had been missing in seaice_evp.F
485      - cleaning up: remove unused seaice_calc_rhs.F
486    o pkg/exf: some cleaning-up:
487      - change various "constants" into runtime parameters
488      - cleaned-up Large&Yeager04 routine which should eventually
489        replace exf_bulkformulae.F (changed names of S/R and CPP)
490        and merged various ALLOW_ATM_WIND options
491     only used with thsice pkg (in thsice_get_exf.F):
492      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
493        which are used when useStabilityFct_overIce=TRUE (= the default)
494      - change default values of ice & snow emissivity and scale downward LW
495        by ice & snow emissivity.
496    o pkg/thsice:
497     fix few little problems, in thsice_calc_thickn.F:
498      - growth vertically (and not laterally) if iceFrac == iceMaskMax
499      - melt only laterally if hIce < hThinIce (as the comments say)
500      and in thsice_extend.F:
501      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
502      - start to form ice as soon as the minimum ice-volume is reachable.
503     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
504      and cpl_aim+ocn
505    o pkg/kpp
506     - move computation of surface related input fields to KPP into a new
507       subroutine kpp_forcing_surf.F
508     - remove wrong (within bi,bj loops) EXCH calls.
509     - little cleaning (add argument myThid in last position, cvs header ...)
510     - for now, fix conservation problem by exchanging KPPviscAz (may not
511       be the best fix)
512    o pkg/seaice
513     - check for inconsistent evp parameter/cpp-flag combination
514     - remove leftover errIO flat for obsolete name list error handling
515    o OpenAD
516     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
517    
518    checkpoint59a
519    o pkg/seaice: some parameter clarifications and a little bit of clean up
520    o pkg/thsice: rename run-time parameters:
521       himin       -> hIceMin
522       himin0      -> hThinIce
523       hihig       -> hThickIce
524       i0          -> i0swFrac
525       transCoef   -> bMeltCoef
526       frac_energy -> fracMelting
527      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
528       with default values (for now) that do not change the results.
529      remove old version of thsice vars advection in pkg/seaice.
530    o in FFIELDS.h:
531      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
532      - make pLoad & sIceLoad always available (but still only used if
533         ATMOSPHERIC_LOADING is #define).
534    o pkg/kpp: replaced _KPP_RL with _RL
535    o bug fixes for vertical diffusivity computations when both KPP and
536        3D diffusivity arrays are used; pkg/kpp/kpp_calc_diff_s & _t.F
537        are no longer updating the vertical diffusivity array
538        (passed as argument) but are (re-) setting those arrays.
539    o pkg/seaice: fix bug in evp solver, while doing that
540      - change (improve?) discretization of stress computations for both
541        cgrid-lsr and evp solver
542      - add a new routine to compute strain rates
543      - the above changes lab_sea results
544      - add no slip conditions for evp solver (off by default), lsr-version
545        may follow
546      - fix exchange for shear at Z-points (does not change lab_sea)
547      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
548        (to force the user to pick a time step since there is not "safe" way
549        of choosing it)
550      - add principal stress diagnostics
551      - rearrange fields for evp a little to avoid having to call a: too many
552        exchanges and b: exchanges for stress trensor components which we do
553        not have.
554      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
555        of evp, complete rewrite for lsr case (latter is does not yet work
556        in all cases)
557    o pkg/kpp: add code to have mixing in shelf ice caverns
558      - add myThid to all kpp routines (long overdue)
559    
560    checkpoint59
561    o pkg/exf:
562      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
563        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
564      - move exf header files from lower_case.h to UPPER_CASE.h ;
565        add missing cvs Header & Name
566      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
567      - add namelist param. selectStressGridPosition, exf_monFreq
568      - retire many _CLIM routines, and remove data.exf_clim
569        + params moved to data.exf
570        + climsst, climsss now handled by exf_set_gen, i.e.
571          climss?period=0 refers to constant field,
572          climss?period=-12 to monthly forcing
573      - split up namelists in data.exf
574    o pkg/seaice:
575      - remove seaice_exch and seaice_exch_uv
576      - remove superfluous exchange of theta
577      - add myThid to seaice_budget_ocean/ice
578      - add new interface for atmospheric wind forcing (C-grid only)
579        + new routine
580        + two new field (taux, tauy for stress over ice)
581        + removed one global field (DAIRN) for C-grid case only
582    o pkg/thsise
583      - 2nd set of modifs for thsice adjoint in conjunction with exf
584    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
585    
586    checkpoint58y_post
587    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
588      vertical diffusivity, similar to that in MOM4; turned on using
589      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
590      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
591    o Added capability for 3D specification of background vertical diffusion
592      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
593      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
594      "data" file that contains the 3D vertical diffusivity coefficients.
595    o ice dynamics (pkg/seaice) with thsice thermodynamics:
596      - add code within pkg thsice to advect & diffuse sea-ice fields
597      similar to (and will replace) what has been added in  seaice_advdiff.F,
598      but: - conserving Mass, Heat & Salt.
599           - better when using non-linear advection scheme (not yet fully tested)
600           - can also be used in atmospheric set-up (for now, only the diffusion).
601    
602    checkpoint58x_post
603    o IO option for global-file compact format:
604      - add options when generating topology (utils/exch2/matlab-topology-generator)
605      - add I/O capability (pkg/mdsio).
606      - adapt utils/matlab/rdmds.m to read this format.
607      for now long-line format not yet supported by pkg/mdsio (& exch2).
608    o shelfice: add a few diagnostics
609    
610    checkpoint58w_post
611    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
612      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
613      (and replace horiVertRatio in NH code).
614      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
615                         and tutorial_plume_on_slope (sensitive to truncation)
616    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
617      directly to drive seaice model (C-grid only)
618    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
619     - reintroduce computation of wind from stress,
620     - compute tau (in exf_bulkformulae.F) from windstress averaged to
621       mass points to avoid tau = 0
622     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
623    o rdmnc.m: make it work with "global" files created with gluemnc
624    o rdmnc.m : some improvements in dealing with singleton dimension
625      (tested on all testreport mnc output files).
626    o genmake2: disable pkg/profiles if netcdf test fails.
627    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
628    o move call to cal_readparms up to make calendar parameters/variable available
629      to all packages
630    
631    checkpoint58v_post
632    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
633      useDynP_inEos_Zc tested.
634    o pkg/exf: changes to properly interpolate/mask/scale initial fields
635    o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
636      and portions thereof.  See read_cs.txt for description and examples.
637    o utils/matlab/cs_grid/bk_line: to compute transport through passages,
638      add a script (grt_circ_bkl.m) to generate broken-line between 2 points,
639      following the great-circle arc between those 2 points.
640    o trap un-initialized variable with pathscale compiler on weddell.mit.edu
641      (thanks to Constantinos): fix few problems and get (almost) all exp to pass.
642    o 2nd-Order Moment Advection Scheme (Prather, 1986): first check-in
643     - enable by setting #define GAD_ALLOW_SOM_ADVECT (in GAD_OPTIONS.h)
644     - used without limiter (AdvScheme=80) or with Prather limiter (AdvScheme=81)
645     - still needs work (not working with some options ; efficiency to improve)
646       and serious testing.
647     - use this scheme for temperature & salinity in 2 advection test exp.:
648       advect_xy & advect_xz, respectively.
649    
650    checkpoint58u_post
651    o new test-exp: fizhi-cs-32x32x40 (40 levels) to replace the 10 levels.
652    o move call to INI_FORCING from PACKAGES_INIT_VARIABLES to INITIALISE_VARIA.
653    o testreport: add option "-skipdir" to skip some test.
654    o exf: when input wind-stress (#undef ALLOW_ATM_WIND), by-pass turbulent
655      momentum calculation.
656    o gad_advection: fix vertAdvecScheme (if different from advectionScheme)
657    o some cleaning: usePickupBeforeC35 no longer supported ; remove this option.
658      remove checkpoint.F and the_correction_step.F (no longer used);
659      do the k loop inside CYCLE_TRACER (supposed to be more efficient).
660    o add option (linFSConserveTr) to correct for tracer source/sink due to
661      Linear Free surface
662    o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine
663    o pkg/thsice: fix reading mnc-pickups
664    
665    checkpoint58t_post
666    o pkg/diagnostics: fix multi-threaded output (when singleCpuIO=F)
667    o pkg/mdsio:
668     - clean-up mdsio_readfield.F & mdsio_writefield_new.F and
669       move to new files: mdsio_read_field.F (S/R MDS_READ_FIELD) &
670       mdsio_write_field.F (S/R MDS_WRITE_FIELD);
671     - fix multi-threaded singleCpuIO option in MDS_WRITE_FIELD
672     - collect old S/R  in one file: mdsio_rw_field.F (now just a call to
673       either MDS_READ_FIELD or MDS_WRITE_FIELD )
674     - new S/R (to replace MDSWRITEMETA), which allows to write more
675       informations (variable names, time ...) to meta files.
676     - modify rdmds.m to give back the meta file content.
677    o pkg/diagnostics: change vertical interpolation to be safer, and more
678       flexible (define p-levels to interpolate to in data.diagnostics);
679      add argument to S/R DIAGNOSTICS_GET_POINTERS to catch the right
680       diagnostic pointer.
681    o pkg/seaice: more cleaning up of seaice_growth, added many comments
682    o pkg/exf: put runoff0 and runoff1 into the appropriate common block
683  o fix multi-category seaice:  o fix multi-category seaice:
684   - change cpp flag SEAICE_MULTILEVEL to more meaningful name:   - change cpp flag SEAICE_MULTILEVEL to more meaningful name:
685     SEAICE_MULTICATEGORY     SEAICE_MULTICATEGORY
686   - fix short wave heat flux   - fix short wave heat flux
687    o pkg/seaice: change default (SEAICE_OPTIONS.h): use C-grid dynamics
688       and allow to use EVP solver. Change forward lab_sea: test both EVP
689       solver and LSR solver, and use C-grid dynamics (like lab_sea adjoint)
690  o Initial check-in of lab_sea adjoint  o Initial check-in of lab_sea adjoint
691    (very similar to natl_box_adjoint/code_seaice)    (very similar to natl_box_adjoint/code_seaice)
692    * used C-grid and EVP solver    * used C-grid and EVP solver
