4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/dic: test for "pickup_dic" file when restarting ;
8      if no pickup-file, can restart with a re-initialised pH (same as it did
9      before) providing pickupStrictlyMatch is set to False.
10    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
11      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
12    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
13      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
14    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
15     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
16       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
17    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
18       scheme to use for vorticty-term ;
19     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
20       (with default selectVortScheme, return to original discretisation)
21     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
22    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
23    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
24      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
25      also fix diagnostics VISCAHW & VISCA4W.
26    
27    checkpoint59o
28    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
29    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
30      move a few statemens out the main loop into separate loops
31    o pkg/shelfice:
32      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
33        (kg/m^2/s), does not break tests, because in verification/isomip,
34        rhoConstFresh=rhoConst (by accident)
35      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
36      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
37        new file model/src/seawater.F, so that they are available for all pkgs.
38      - convert potential temperature into in-situ temperature. This changes the
39        isomip tests => update tests
40    o add a flag writePickupAtEnd (default=true) to be able to suppress
41      writing a pickup at the last timestep
42    o tools/mpack-1.6 :
43      - disable automake (not working) and autoconf (not needed).
44      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
45        also cleaner with much less compilation warnings.
46    o pkg/profiles:
47      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
48      (for "less than 32 characters name" compiler requirement)
49    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
50      conditions that have a different sampling frequency than S/T/U/V obcs
51    o pkg/diagnostics (stats-diags):
52      - fix global Min/Max in case 1 processor get only empty tiles
53    o genmake2: replace (4 times)
54         make genmake_tc_1.o >> genmake_warnings 2>&1
55      with
56         COMM="$CC $CFLAGS -c genmake_tc_1.c"
57         echo $COMM >> genmake_warnings
58         $COMM >> genmake_warnings 2>&1
59      to make genmake2 always see the value of CC as specified in the optfile.
60    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
61      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
62      - modify verification advect_cs test to test SOM-advection on CS-grid.
63    o pkg/ctrl:
64      - Rewrite of ctrl_map_ini_ecco.F,
65        introducing a generic routine (ctrl_map_ini_gen.F).
66      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
67    
68    checkpoint59n
69    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
70      number in dedicate array "hdiag":
71      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
72        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
73      - many small changes (integer format) for large number of diagnostics
74      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
75        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
76    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
77      usingSphericalGrid, this allows to define the rotated grid coordinates
78      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
79      geographical coordinates according to the inverse of the rotation defined
80      by the Euler angles, so that Coriolis parameter and online-interpolation by
81      exf works with the geographical coordinates on XC/YC/XG/YG.
82      Naturally, this feature does not work with all packages, so some
83      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
84      profiles), because there the coordinates are assumed to be regular
85      spherical grid coordinates.
86    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
87      - introduce isopycnal diffusion coefficient control.
88    o tools/adjoint_options:
89      - additional control vector components.
90    o pkg/mnc: have mnc create marginally meaning full coordinate variables
91      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
92    o pkg/mypackage:
93      - add example of read/write pickup for state-var ;
94      - add entry points to the main code for state-vars diags & write-pickup.
95    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
96      transitions for useExfYearlyFields
97      - add new subroutine that determines the file to read from for
98        use*YearlyFields = .TRUE. and .FALSE.
99      - add a verification experiment to global_with_exf that tests
100        useExfYearlyFields with USE_EXF_INTERPOLATION defined
101    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
102      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
103      subroutines (which could be generated from a template, because they are
104      almost identical), for now they are included in obcs_prescribe_read.F for
105      simplicity
106    o pkg/exf:
107      - add a little more diagnostic to exf_interp_read (in analogy to
108        mds_read_field, can be turned off with debugLevel < debugLevA=1)
109      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
110        ugly but fast by unrolling short inner loops, inserting a unroll=8
111        directive in routine lagran, and splitting a loop and making do while the
112        outermost loop (the latter requires the intoduction of index arrays)
113    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
114    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
115      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
116    o verification/seaice_obcs: updated for restart test and latest options
117    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
118      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
119      for now this is only available for the C-grid code and also within
120      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
121    
122    checkpoint59m
123    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
124      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
125    o gad_som : fix flux output (& diagnostics) to have same units as other  
126      advection scheme fluxes (was previously multiplied by deltaT).  
127    o added verification/seaice_obcs both to test seaice open boundaries
128      and to provide an example matlab scrpt for generating them
129    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
130    o pkg/salt_plume: clean up salt_plume_frac.F to
131      remove redundancy in PlumeMethod 1 and 4
132    o pkg/kpp: added saltplume diagnostics
133    o pkg/obcs and pkg/seaice:
134      - do not set uice and vice to zero when OB*icefile are unspecified
135      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
136      - moved seaice tracer obcs after call to seaice_growth
137    o pkg/salt_plume: added various options for salt plume depth
138      criterion and for vertical distribution of the salt
139    
140    checkpoint59l
141    o pkg/ptracers: new version of ptracers pickup:
142      read meta file and write only fields which are needed to restart.
143      ( same logic as main pickup file ; also using pickupStrictlyMatch )
144    o pkg/seaice:
145      - add timescale for melting due to warm mixed layer as a means of
146        setting SEAICE_availHeatFrac more conveniently
147      - add a CPP-flag/runtime parameter check for flooding algorithm
148      - reformulated availHeat in seaice_growth.F to be independent of AREA
149    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
150      unit changes
151    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
152    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
153      SX vector computer.
154    o pkg/seaice:
155      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
156        seaice forcing fields can now be read only through pkg/exf
157      - removed some unused halos
158    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
159    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
160      or U/VICE from U/VWIND before computing U/VSTRESS
161    
162    checkpoint59k
163    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
164      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
165    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
166      all experiments pass when compile with un-initialised var. checking option.
167    o added pkg/salt_plume
168    o script to test restart (for now, in MITgcm_contrib/jmc_script)
169    o pkg/seaice: new read/write pickup version.
170      read meta file and write only fields which are needed to restart.
171      ( same logic as main pickup file ; also using pickupStrictlyMatch )
172    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
173    o lab_sea.hb87: modify the domain & update output.hb87.txt :
174      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
175      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
176      process. Fixed here by closing the domain at the Northern boundary.
177    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
178    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
179      a set of consecutive levels in/from a 3-D array.
180    o pkg/ptracers:
181      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
182      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
183    
184    checkpoint59j
185    o in pkgs: dic, obcs, offline, rbcs:
186      standard way to compute coeff. for time interpolation between 2 time reccords
187      which retains full precision (& make results less dependent on compiler).
188      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
189    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
190      packages instead of reading ice cover and wind speed separately
191    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
192     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
193      to allow to compile customized code before the update)
194    o cleaning-up:
195      - fix CPP instruction syntax in pkg/obcs
196      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
197        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
198      - fix some threads issue in IO parts.
199    o pkg/dic:
200      - add tons of "_d 0" (--> much better testreports !)
201       and then update outputs of tutorial_global_oce_biogeo
202    o pkg/mom_fluxform:
203      add a special version of momentum advection intended to conserve momentum
204      next to a bathymetry step or a coastline edge. (default = off = #undef)
205    o new read/write pickup version:
206      - for now, only implemented for main (mdsio) pickup file.
207      - write out only what is needed to restart; merge pickup_nh , pickup_ph
208        and main pickup together.
209      - read meta file; read only what is needed to restart; stop if a field
210        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
211        if it make sense (even if the restart is not perfect).
212      - if no meta file, assume that pickup to read corresponds exactly to
213        a pickup that would currently be written.
214      - read pickup written in the old format (until checkpoint59i) if it
215        recognizes an old meta file (no field-list).
216      - add a meta file in exp. which starts from a pickup: 2 cases:
217        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
218         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
219        b) a meta file describing the content of the associated pickup file
220         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
221    o pkg/mdsio & pkg/rw:
222      - new routine to read a meta file ; new set of routine to read
223        Multiple-fields file (with meta file).
224    o added open boundary conditions capability for seaice
225        HSNOW, HSALT, UICE, and VICE
226    
227    checkpoint59i
228    o adjoint:
229      * fix multiDimAdvection adjoint
230        (partial recomputation problem by TAF for fVerT(:,:,kDown)
231        and comlev1 size definition (maxpass vs. max. number of tracers)
232      * verification/global_ocean.90x45x15 adjoint now tests
233        NLFS and multiDimAdvection using DST3 (=30)
234      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
235    o pkg/kpp: add "_d 0" to real constant (if missing);
236      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
237      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
238    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
239      for internal parameters related to restart process (formerly from PARAMS.h)
240      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
241    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
242      as argument. (only atm2d & obcs write_pickup have not yet been updated)
243    o pkg/monitor:
244      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
245      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
246      - account for deep Atmosphere factor and density factor (anelastic)
247    o added open boundary conditions capability for seaice HEFF and AREA
248    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
249      thermodynamics
250      - requires a little reorganization, which affects the testreport results
251        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
252        so that now the conservative form is tested
253      - add a few comments
254    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
255    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
256    o add new diagnostics to seaice: advective, diffusive fluxes (only for
257      multidim-advection, for scheme 2 they are not filled) and transports,
258      thermodynamic growth rates
259    o change units of EmPmR (inside the code, + within coupling interface)
260      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
261      Affects results @ truncation level (cg2d match) and update output of
262       experiments: lab_sea(6), global_ocean.90x40x15(10),
263      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
264      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
265      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
266      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
267    
268    checkpoint59h
269    o pkg/exf:
270      - improve vectorization by moving if-statement out of loops in
271        exf_mapfields, exf_radiation
272      - exf_bulkformulae.F: introduce 2D fields and vectorize code
273    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
274    o testreport:
275      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
276        monitor & update offline_exf_seaice exp. output.
277      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
278    o pkg/seaice:
279      - bug fix in the evp solver: boundary conditions were affected be
280        masking of zMax/zMin (changes results)
281      - minor bug fix in boundary conditions in seaice_calc_strainrates
282        (changes results for no_slip)
283      - seaice_lsr.F: make interpolation of eta dependent on boundaries
284      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
285      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
286        stress formulation and no-slip boundary conditions
287  o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP  o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
