4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/seaice: add os7mp as an advection scheme
8                  add check for advection schemes
9                  add a flag for restoring T and S underneath sea ice
10    o pkg/my82: add netcdf-support and diagnostics
11    o thsice pkg:
12      - Now hsMax limits snow heitght by turning it into ice following
13        flooding scheme (and now conserving energy)
14      - Slight rewriting of the formula in thsice_calc_thick.F
15      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
16        --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
17    
18    checkpoint59p
19    o gchem / dic / cfc :
20      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
21      - add new parameter files: "data.dic" & "data.cfc" ;
22      - various re-arrangement in initialisation & header file ;
23      - fix tutorial_global_oce_biogeo for multi-threaded test.
24    o pkg/dic: test for "pickup_dic" file when restarting ;
25      if no pickup-file, can restart with a re-initialised pH (same as it did
26      before) providing pickupStrictlyMatch is set to False.
27    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
28      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
29    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
30      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
31    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
32     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
33       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
34    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
35       scheme to use for vorticty-term ;
36     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
37       (with default selectVortScheme, return to original discretisation)
38     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
39    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
40    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
41      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
42      also fix diagnostics VISCAHW & VISCA4W.
43    
44    checkpoint59o
45    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
46    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
47      move a few statemens out the main loop into separate loops
48    o pkg/shelfice:
49      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
50        (kg/m^2/s), does not break tests, because in verification/isomip,
51        rhoConstFresh=rhoConst (by accident)
52      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
53      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
54        new file model/src/seawater.F, so that they are available for all pkgs.
55      - convert potential temperature into in-situ temperature. This changes the
56        isomip tests => update tests
57    o add a flag writePickupAtEnd (default=true) to be able to suppress
58      writing a pickup at the last timestep
59    o tools/mpack-1.6 :
60      - disable automake (not working) and autoconf (not needed).
61      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
62        also cleaner with much less compilation warnings.
63    o pkg/profiles:
64      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
65      (for "less than 32 characters name" compiler requirement)
66    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
67      conditions that have a different sampling frequency than S/T/U/V obcs
68    o pkg/diagnostics (stats-diags):
69      - fix global Min/Max in case 1 processor get only empty tiles
70    o genmake2: replace (4 times)
71         make genmake_tc_1.o >> genmake_warnings 2>&1
72      with
73         COMM="$CC $CFLAGS -c genmake_tc_1.c"
74         echo $COMM >> genmake_warnings
75         $COMM >> genmake_warnings 2>&1
76      to make genmake2 always see the value of CC as specified in the optfile.
77    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
78      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
79      - modify verification advect_cs test to test SOM-advection on CS-grid.
80    o pkg/ctrl:
81      - Rewrite of ctrl_map_ini_ecco.F,
82        introducing a generic routine (ctrl_map_ini_gen.F).
83      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
84    
85    checkpoint59n
86    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
87      number in dedicate array "hdiag":
88      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
89        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
90      - many small changes (integer format) for large number of diagnostics
91      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
92        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
93    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
94      usingSphericalGrid, this allows to define the rotated grid coordinates
95      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
96      geographical coordinates according to the inverse of the rotation defined
97      by the Euler angles, so that Coriolis parameter and online-interpolation by
98      exf works with the geographical coordinates on XC/YC/XG/YG.
99      Naturally, this feature does not work with all packages, so some
100      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
101      profiles), because there the coordinates are assumed to be regular
102      spherical grid coordinates.
103    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
104      - introduce isopycnal diffusion coefficient control.
105    o tools/adjoint_options:
106      - additional control vector components.
107    o pkg/mnc: have mnc create marginally meaning full coordinate variables
108      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
109    o pkg/mypackage:
110      - add example of read/write pickup for state-var ;
111      - add entry points to the main code for state-vars diags & write-pickup.
112    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
113      transitions for useExfYearlyFields
114      - add new subroutine that determines the file to read from for
115        use*YearlyFields = .TRUE. and .FALSE.
116      - add a verification experiment to global_with_exf that tests
117        useExfYearlyFields with USE_EXF_INTERPOLATION defined
118    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
119      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
120      subroutines (which could be generated from a template, because they are
121      almost identical), for now they are included in obcs_prescribe_read.F for
122      simplicity
123    o pkg/exf:
124      - add a little more diagnostic to exf_interp_read (in analogy to
125        mds_read_field, can be turned off with debugLevel < debugLevA=1)
126      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
127        ugly but fast by unrolling short inner loops, inserting a unroll=8
128        directive in routine lagran, and splitting a loop and making do while the
129        outermost loop (the latter requires the intoduction of index arrays)
130    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
131    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
132      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
133    o verification/seaice_obcs: updated for restart test and latest options
134    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
135      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
136      for now this is only available for the C-grid code and also within
137      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
138    
139    checkpoint59m
140    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
141      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
142    o gad_som : fix flux output (& diagnostics) to have same units as other  
143      advection scheme fluxes (was previously multiplied by deltaT).  
144    o added verification/seaice_obcs both to test seaice open boundaries
145      and to provide an example matlab scrpt for generating them
146    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
147    o pkg/salt_plume: clean up salt_plume_frac.F to
148      remove redundancy in PlumeMethod 1 and 4
149    o pkg/kpp: added saltplume diagnostics
150    o pkg/obcs and pkg/seaice:
151      - do not set uice and vice to zero when OB*icefile are unspecified
152      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
153      - moved seaice tracer obcs after call to seaice_growth
154    o pkg/salt_plume: added various options for salt plume depth
155      criterion and for vertical distribution of the salt
156    
157    checkpoint59l
158    o pkg/ptracers: new version of ptracers pickup:
159      read meta file and write only fields which are needed to restart.
160      ( same logic as main pickup file ; also using pickupStrictlyMatch )
161    o pkg/seaice:
162      - add timescale for melting due to warm mixed layer as a means of
163        setting SEAICE_availHeatFrac more conveniently
164      - add a CPP-flag/runtime parameter check for flooding algorithm
165      - reformulated availHeat in seaice_growth.F to be independent of AREA
166    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
167      unit changes
168    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
169    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
170      SX vector computer.
171    o pkg/seaice:
172      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
173        seaice forcing fields can now be read only through pkg/exf
174      - removed some unused halos
175    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
176    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
177      or U/VICE from U/VWIND before computing U/VSTRESS
178    
179    checkpoint59k
180    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
181      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
182    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
183      all experiments pass when compile with un-initialised var. checking option.
184    o added pkg/salt_plume
185    o script to test restart (for now, in MITgcm_contrib/jmc_script)
186    o pkg/seaice: new read/write pickup version.
187      read meta file and write only fields which are needed to restart.
188      ( same logic as main pickup file ; also using pickupStrictlyMatch )
189    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
190    o lab_sea.hb87: modify the domain & update output.hb87.txt :
191      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
192      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
193      process. Fixed here by closing the domain at the Northern boundary.
194    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
195    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
196      a set of consecutive levels in/from a 3-D array.
197    o pkg/ptracers:
198      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
199      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
200    
201    checkpoint59j
202    o in pkgs: dic, obcs, offline, rbcs:
203      standard way to compute coeff. for time interpolation between 2 time reccords
204      which retains full precision (& make results less dependent on compiler).
205      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
206    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
207      packages instead of reading ice cover and wind speed separately
208    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
209     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
210      to allow to compile customized code before the update)
211    o cleaning-up:
212      - fix CPP instruction syntax in pkg/obcs
213      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
214        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
215      - fix some threads issue in IO parts.
216    o pkg/dic:
217      - add tons of "_d 0" (--> much better testreports !)
218       and then update outputs of tutorial_global_oce_biogeo
219    o pkg/mom_fluxform:
220      add a special version of momentum advection intended to conserve momentum
221      next to a bathymetry step or a coastline edge. (default = off = #undef)
222    o new read/write pickup version:
223      - for now, only implemented for main (mdsio) pickup file.
224      - write out only what is needed to restart; merge pickup_nh , pickup_ph
225        and main pickup together.
226      - read meta file; read only what is needed to restart; stop if a field
227        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
228        if it make sense (even if the restart is not perfect).
229      - if no meta file, assume that pickup to read corresponds exactly to
230        a pickup that would currently be written.
231      - read pickup written in the old format (until checkpoint59i) if it
232        recognizes an old meta file (no field-list).
233      - add a meta file in exp. which starts from a pickup: 2 cases:
234        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
235         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
236        b) a meta file describing the content of the associated pickup file
237         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
238    o pkg/mdsio & pkg/rw:
239      - new routine to read a meta file ; new set of routine to read
240        Multiple-fields file (with meta file).
241    o added open boundary conditions capability for seaice
242        HSNOW, HSALT, UICE, and VICE
243    
244    checkpoint59i
245    o adjoint:
246      * fix multiDimAdvection adjoint
247        (partial recomputation problem by TAF for fVerT(:,:,kDown)
248        and comlev1 size definition (maxpass vs. max. number of tracers)
249      * verification/global_ocean.90x45x15 adjoint now tests
250        NLFS and multiDimAdvection using DST3 (=30)
251      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
252    o pkg/kpp: add "_d 0" to real constant (if missing);
253      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
254      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
255    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
256      for internal parameters related to restart process (formerly from PARAMS.h)
257      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
258    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
259      as argument. (only atm2d & obcs write_pickup have not yet been updated)
260    o pkg/monitor:
261      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
262      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
263      - account for deep Atmosphere factor and density factor (anelastic)
264    o added open boundary conditions capability for seaice HEFF and AREA
265    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
266      thermodynamics
267      - requires a little reorganization, which affects the testreport results
268        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
269        so that now the conservative form is tested
270      - add a few comments
271    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
272    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
273    o add new diagnostics to seaice: advective, diffusive fluxes (only for
274      multidim-advection, for scheme 2 they are not filled) and transports,
275      thermodynamic growth rates
276    o change units of EmPmR (inside the code, + within coupling interface)
277      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
278      Affects results @ truncation level (cg2d match) and update output of
279       experiments: lab_sea(6), global_ocean.90x40x15(10),
280      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
281      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
282      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
283      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
284    
285    checkpoint59h
286    o pkg/exf:
287      - improve vectorization by moving if-statement out of loops in
288        exf_mapfields, exf_radiation
289      - exf_bulkformulae.F: introduce 2D fields and vectorize code
290    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
291    o testreport:
292      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
293        monitor & update offline_exf_seaice exp. output.
294      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
295    o pkg/seaice:
296      - bug fix in the evp solver: boundary conditions were affected be
297        masking of zMax/zMin (changes results)
298      - minor bug fix in boundary conditions in seaice_calc_strainrates
299        (changes results for no_slip)
300      - seaice_lsr.F: make interpolation of eta dependent on boundaries
301      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
302      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
303        stress formulation and no-slip boundary conditions
304    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
305      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
306    o pkg/seaice: a first HSALT time stepping equation has been checked in
307    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
308      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
309      without requiring DO-IF statements
310    o pkg/thsice:
311      use continuous power-law function for partition of energy between lateral
312      melting/freezing and thinning/thickening ; old code using step function
313      still available with #undef THSICE_FRACEN_POWERLAW
314      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
315    o testreport: change AD testing : check against results/output_adm.txt
316      using same scripts as for forward test.
317    
318    checkpoint59g
319    o adjoint testing: in preparation for changing testreport:
320      - output format: cost and grad written on separated lines
321      - ad output results in directory "results" (instead of "results_ad")
322    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
