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