4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/mypackage:
8      - add example of read/write pickup for state-var ;
9      - add entry points to the main code for state-vars diags & write-pickup.
10    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
11      transitions for useExfYearlyFields
12      - add new subroutine that determines the file to read from for
13        use*YearlyFields = .TRUE. and .FALSE.
14    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
15      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
16      subroutines (which could be generated from a template, because they are
17      almost identical), for now they are included in obcs_prescribe_read.F for
18      simplicity
19    o pkg/exf:
20      - add a little more diagnostic to exf_interp_read (in analogy to
21        mds_read_field, can be turned off with debugLevel < debugLevA=1)
22      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
23        ugly but fast by unrolling short inner loops, inserting a unroll=8
24        directive in routine lagran, and splitting a loop and making do while the
25        outermost loop (the latter requires the intoduction of index arrays)
26    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
27    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
28      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
29    o verification/seaice_obcs: updated for restart test and latest options
30    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
31      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
32      for now this is only available for the C-grid code and also within
33      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
34    
35    checkpoint59m
36    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
37      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
38    o gad_som : fix flux output (& diagnostics) to have same units as other  
39      advection scheme fluxes (was previously multiplied by deltaT).  
40    o added verification/seaice_obcs both to test seaice open boundaries
41      and to provide an example matlab scrpt for generating them
42    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
43    o pkg/salt_plume: clean up salt_plume_frac.F to
44      remove redundancy in PlumeMethod 1 and 4
45    o pkg/kpp: added saltplume diagnostics
46    o pkg/obcs and pkg/seaice:
47      - do not set uice and vice to zero when OB*icefile are unspecified
48      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
49      - moved seaice tracer obcs after call to seaice_growth
50    o pkg/salt_plume: added various options for salt plume depth
51      criterion and for vertical distribution of the salt
52    
53    checkpoint59l
54    o pkg/ptracers: new version of ptracers pickup:
55      read meta file and write only fields which are needed to restart.
56      ( same logic as main pickup file ; also using pickupStrictlyMatch )
57    o pkg/seaice:
58      - add timescale for melting due to warm mixed layer as a means of
59        setting SEAICE_availHeatFrac more conveniently
60      - add a CPP-flag/runtime parameter check for flooding algorithm
61      - reformulated availHeat in seaice_growth.F to be independent of AREA
62    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
63      unit changes
64    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
65    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
66      SX vector computer.
67    o pkg/seaice:
68      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
69        seaice forcing fields can now be read only through pkg/exf
70      - removed some unused halos
71    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
72    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
73      or U/VICE from U/VWIND before computing U/VSTRESS
74    
75    checkpoint59k
76    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
77      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
78    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
79      all experiments pass when compile with un-initialised var. checking option.
80    o added pkg/salt_plume
81    o script to test restart (for now, in MITgcm_contrib/jmc_script)
82    o pkg/seaice: new read/write pickup version.
83      read meta file and write only fields which are needed to restart.
84      ( same logic as main pickup file ; also using pickupStrictlyMatch )
85    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
86    o lab_sea.hb87: modify the domain & update output.hb87.txt :
87      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
88      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
89      process. Fixed here by closing the domain at the Northern boundary.
90    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
91    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
92      a set of consecutive levels in/from a 3-D array.
93    o pkg/ptracers:
94      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
95      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
96    
97    checkpoint59j
98    o in pkgs: dic, obcs, offline, rbcs:
99      standard way to compute coeff. for time interpolation between 2 time reccords
100      which retains full precision (& make results less dependent on compiler).
101      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
102    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
103      packages instead of reading ice cover and wind speed separately
104    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
105     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
106      to allow to compile customized code before the update)
107    o cleaning-up:
108      - fix CPP instruction syntax in pkg/obcs
109      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
110        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
111      - fix some threads issue in IO parts.
112    o pkg/dic:
113      - add tons of "_d 0" (--> much better testreports !)
114       and then update outputs of tutorial_global_oce_biogeo
115    o pkg/mom_fluxform:
116      add a special version of momentum advection intended to conserve momentum
117      next to a bathymetry step or a coastline edge. (default = off = #undef)
118    o new read/write pickup version:
119      - for now, only implemented for main (mdsio) pickup file.
120      - write out only what is needed to restart; merge pickup_nh , pickup_ph
121        and main pickup together.
122      - read meta file; read only what is needed to restart; stop if a field
123        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
124        if it make sense (even if the restart is not perfect).
125      - if no meta file, assume that pickup to read corresponds exactly to
126        a pickup that would currently be written.
127      - read pickup written in the old format (until checkpoint59i) if it
128        recognizes an old meta file (no field-list).
129      - add a meta file in exp. which starts from a pickup: 2 cases:
130        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
131         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
132        b) a meta file describing the content of the associated pickup file
133         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
134    o pkg/mdsio & pkg/rw:
135      - new routine to read a meta file ; new set of routine to read
136        Multiple-fields file (with meta file).
137    o added open boundary conditions capability for seaice
138        HSNOW, HSALT, UICE, and VICE
139    
140    checkpoint59i
141    o adjoint:
142      * fix multiDimAdvection adjoint
143        (partial recomputation problem by TAF for fVerT(:,:,kDown)
144        and comlev1 size definition (maxpass vs. max. number of tracers)
145      * verification/global_ocean.90x45x15 adjoint now tests
146        NLFS and multiDimAdvection using DST3 (=30)
147      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
148    o pkg/kpp: add "_d 0" to real constant (if missing);
149      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
150      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
151    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
152      for internal parameters related to restart process (formerly from PARAMS.h)
153      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
154    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
155      as argument. (only atm2d & obcs write_pickup have not yet been updated)
156    o pkg/monitor:
157      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
158      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
159      - account for deep Atmosphere factor and density factor (anelastic)
160    o added open boundary conditions capability for seaice HEFF and AREA
161    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
162      thermodynamics
163      - requires a little reorganization, which affects the testreport results
164        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
165        so that now the conservative form is tested
166      - add a few comments
167    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
168    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
169    o add new diagnostics to seaice: advective, diffusive fluxes (only for
170      multidim-advection, for scheme 2 they are not filled) and transports,
171      thermodynamic growth rates
172    o change units of EmPmR (inside the code, + within coupling interface)
173      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
174      Affects results @ truncation level (cg2d match) and update output of
175       experiments: lab_sea(6), global_ocean.90x40x15(10),
176      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
177      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
178      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
179      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
180    
181    checkpoint59h
182    o pkg/exf:
183      - improve vectorization by moving if-statement out of loops in
184        exf_mapfields, exf_radiation
185      - exf_bulkformulae.F: introduce 2D fields and vectorize code
186    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
187    o testreport:
188      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
189        monitor & update offline_exf_seaice exp. output.
190      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
191    o pkg/seaice:
192      - bug fix in the evp solver: boundary conditions were affected be
193        masking of zMax/zMin (changes results)
194      - minor bug fix in boundary conditions in seaice_calc_strainrates
195        (changes results for no_slip)
196      - seaice_lsr.F: make interpolation of eta dependent on boundaries
197      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
198      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
199        stress formulation and no-slip boundary conditions
200    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
201      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
202    o pkg/seaice: a first HSALT time stepping equation has been checked in
203    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
204      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
205      without requiring DO-IF statements
206    o pkg/thsice:
207      use continuous power-law function for partition of energy between lateral
208      melting/freezing and thinning/thickening ; old code using step function
209      still available with #undef THSICE_FRACEN_POWERLAW
210      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
211    o testreport: change AD testing : check against results/output_adm.txt
212      using same scripts as for forward test.
213    
214    checkpoint59g
215    o adjoint testing: in preparation for changing testreport:
216      - output format: cost and grad written on separated lines
217      - ad output results in directory "results" (instead of "results_ad")
218    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
219    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
220    o pkg/ecco: allow user defined cost function contributions
221    o testreport:
222      Allow to choose (per experiment) the list of tested output variables
223       and the main variable (used to issue a pass/FAIL ) ;
224      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
225      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
226      Also modify printing of summary:
227       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
228       b) echo the list of tested variables in the individual summary.txt of
229          each experiment.
230    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
231      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
232      (but still depend on the tile decompostion of the domain).
233    o pkg/seaice: change a discretization detail to make the B-grid code
234      "more symmetric". This change is likely to remove all "ridges/leads" that
235      where quasi-aligned with the grid in B-grid solutions. It may also be
236      the solution to the stress coupling issues with the B-grid.
237    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
238      remove .cvsignore from input dir. (since testreport no longer run here).
239    o pkg/thsice:
240     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
241     - fix reshaping of sea-ice just after advection:
242       melt all the ice only if ice-volume is too small.
243     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
244       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
245     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
246    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
247      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
248    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
249      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
250      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
251      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
252      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
253      -> update output.txt
254    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
255     this affects truncation error: -> update output.txt of exp:
256      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
257      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
258    
259    checkpoint59f
260    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
261    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
262      a bounded range (in forward mode)
263    o pkg/ecco, ctrl, autodiff and mom_common:
264     internal parameter controls, completements of implementations
265    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
266    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
267      (not seem any difference in testing results).
268    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
269       at face corners.
270    o pkg/generic_advdiff:
271     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
272      loop range indices for computing vertical advection tendency
273      and do the calculation in the interior only (no overlap) ;
274      for now, only implemented for SOM advection (to save CPU time).
275     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
276    o exch2 adjoint
277      First set of changes:
278      - add exch2 hand-written adjoint templates
279      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
280        This will require cleanup in pkg/autodiff/*.F
281        (changed routines currently kept separate in verif. code/)
282      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
283        that used to hide exch2 or cubed-sphere specific code
284        (commented via 'cph-exch2')
285    o pkg/seaice
286      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
287    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
288       output of global_ocean.cs32x15.thsice .
289    
290    checkpoint59e
291    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
292      for B-grid vector (not yet tested) and C-grid vector (<- only used
293      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
294    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
295      (#ifdef ALLOW_SALT_PLUME)
296    o gather_2d/scatter_2d: removed halo regions
297    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
298      scheme and the corresponding test case (under front_relax dir). For now,
299      only available with Skew-flux form and not yet tested in realistic set-up.
300      adjoint: store directives updated, but gradient checks deteriorated,
301      so maybe GM/Redi adjoint is now broken.
302    o seaice adjoint
303      * add AREA, HEFF, HSNOW as control variable
304        (should not change lab_sea results)
305      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
306    o pkg/seaice:
307      * added computation of saltFlux in seaice_growth;
308        For time being, sea ice salinity is assumed constant
309        contribution of snow flooding to freshening of sea ice is neglected.
310        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
311        defaults to 0.0 in order to maintain backward compatibility.
312        Typical values for SEAICE_salinity are 4 to 10 g/kg.
313      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
314      * added SEAICE_availHeatFrac, which specifies fraction of surface level
315        heat content used to melt or grow ice
316      * commented out cap of HICE: it helps keep ice thinner
317      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
318      * applied OBCS T/S mask to HEFFM sea ice mask
319    
320    checkpoint59d
321    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
322     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
323     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
324    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
325     and change default value of parameter "GM_Small_Number";
326     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
327       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
328       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
329    o pkg/ecco: cost function when applying pkg/smooth to controls
330    o pkg/ctrl: add forcingPrecond run time parameter
331    o pkg/seaice:
332     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
333     - fix bug in metric terms of u-equation in LSR solver (implicit part),
334       changes verification/lab_sea
335     - rearrange implicit part of u-equation in LSR solver to make it easier to
336       read, understand, and debug. This causes changes at the truncation level.
337     - fix (serious) bug in the boundary conditions (sign error in the implicit
338       part) of the LSR solver. Changes all LSR results.
339     - fixed problem with HSNOW initialization to avoid thick snow when AREA
340       is initilized with small values - does not change lab_sea results.
341     - added HsnowFile initialization capability
342    o pkg/smooth: addition to model/src and pkg/ctrl so allow
