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