4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o autodiff
8      Change default for TAF usage by removing argument '-nonew_arg'
9      This changes TAF subroutine argument list (ordering of active var.)
10      Omission of this flag leads to incompatibility w.r.t. TAMC
11      To restore TAMC-compatibility, need following modifs:
12      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
13      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
14      Tested TAF version is 1.9.22
15      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
16    
17    checkpoint60
18    --->>> This is the last checkpoint for which generating the adjoint
19    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
20    --->>> by default.
21    --->>> Future checkpoints will ommit this flag by default.
22    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
23    o pkg/grdchk: Add gradient check to etan0 perturbations.
24    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
25    o pkg/autodiff: more flexibility in zeroadj.
26      model/src: modifying do_oceanic_phys.F accordingly.
27    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
28    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
29      special setup of gmredi for which the adjoint is stable
30      enough for parameter optimization.
31    o bridging the gap between eddy stress and GM.
32      -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
33          along with a change in CPP option (now ALLOW_EDDYPSI).
34      -> when using GM w/ GM_AdvForm:
35          The total eddy streamfunction (Psi = eddyPsi + K x Slope)
36          is applied either in the tracer Eq. or in momentum Eq.
37          depending on data.gmredi (intro. GM_InMomAsStress).
38      -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
39      The key modifications are in model/src/taueddy_external_forcing.F
40      pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F
41    
42    checkpoint59r
43    o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array
44      from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
45      fix option to read coriolis(@ cell-corner) from files with CS-grid.
46    o pkg/mnc: add some attributes to standard 1D-coordinate variables
47    o pkg/diagnostics: enforce missing_value attribute for scalar variables at
48      mass points, when using mnc for output
49      - add runtime parameter (missing_value, missing_value_int) to override
50        default (which is the value of getcon('UNDEF'))
51    o pkg/mnc: prepare mnc for the actual use of missing values with the
52      diagnostics package: small fix in mnc_cw_readwrite.template and more
53      initialisation of never used fields
54      - replace mnc_common.h and mnc_id_header.h with corresponding upper case
55      versions
56    o pkg/thsice/thsice_ini_vars.F added default initial values so that
57      thermodynamics sea ice solver does not blow up when some initial fields
58      are missing.
59    o move from external_forcing_surf.F to ini_forcing.F
60      the p-coord. hack consisting in using pLoad to set phi0surf ;
61      update output of tutorial_global_oce_in_p (affected @ truncation level).
62    o Freshen up a bit hs94.1x64x5, notably:
63      remove rotationPeriod and tRef=5*0. (adjoint only), and add
64      exactConserv=.TRUE.
65    o pkg/generic_advdiff:
66      change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only
67      applies to files where Temperature & Salinity 2nd Order moments are used.
68    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
69      this uses a dynamically allocated internal state data structure
70      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
71      and requires a fortran 90 compiler
72    
73    checkpoint59q
74    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
75       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
76    o Refresh tutorial_global_oce_biogeo, notably:
77      - change bathymetry (put back seamounts in ACC, use hFacs)
78      - change EOS (POLY3 --> JMD95Z)
79      - use Bryan-Lewis vertical diffusivity
80      - use multidimensional advection
81      - remove old virtual virtual in dic pkg, now done through ptracer pkg
82      - change a couple of parameters in dic pkg
83    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
84    o pkg/obcs: change default to OBCSfixTopo = .true.,
85      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
86      - replace "debugMode" with "debugLevel .GE. debLevB"
87    o implementation of TAF directives for gchem,cfc,dic
88    o remove "exp5" (replaced by tutorial_deep_convection).
89    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
90      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
91      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
92      --> changes results in exp4, seaice_obcs
93    o tutorial_deep_convection :
94      update the set-up and increase resolution and domain size ; start
95      from pseudo initial conditions = output at t=120mn in order to see
96      something happening when running testreport.
97    o pkg/seaice: add os7mp as an advection scheme
98                  add check for advection schemes
99                  add a flag for restoring T and S underneath sea ice
100    o pkg/my82: add netcdf-support and diagnostics
101    o thsice pkg:
102      - Now hsMax limits snow height by turning it into ice following
103        flooding scheme (and now conserving energy)
104      - Slight rewriting of the formula in thsice_calc_thick.F
105      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
106      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
107    
108    checkpoint59p
109    o gchem / dic / cfc :
110      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
111      - add new parameter files: "data.dic" & "data.cfc" ;
112      - various re-arrangement in initialisation & header file ;
113      - fix tutorial_global_oce_biogeo for multi-threaded test.
114    o pkg/dic: test for "pickup_dic" file when restarting ;
115      if no pickup-file, can restart with a re-initialised pH (same as it did
116      before) providing pickupStrictlyMatch is set to False.
117    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
118      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
119    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
120      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
121    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
122     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
123       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
124    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
125       scheme to use for vorticty-term ;
126     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
127       (with default selectVortScheme, return to original discretisation)
128     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
129    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
130    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
131      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
132      also fix diagnostics VISCAHW & VISCA4W.
133    
134    checkpoint59o
135    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
136    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
137      move a few statemens out the main loop into separate loops
138    o pkg/shelfice:
139      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
140        (kg/m^2/s), does not break tests, because in verification/isomip,
141        rhoConstFresh=rhoConst (by accident)
142      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
143      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
144        new file model/src/seawater.F, so that they are available for all pkgs.
145      - convert potential temperature into in-situ temperature. This changes the
146        isomip tests => update tests
147    o add a flag writePickupAtEnd (default=true) to be able to suppress
148      writing a pickup at the last timestep
149    o tools/mpack-1.6 :
150      - disable automake (not working) and autoconf (not needed).
151      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
152        also cleaner with much less compilation warnings.
153    o pkg/profiles:
154      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
155      (for "less than 32 characters name" compiler requirement)
156    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
157      conditions that have a different sampling frequency than S/T/U/V obcs
158    o pkg/diagnostics (stats-diags):
159      - fix global Min/Max in case 1 processor get only empty tiles
160    o genmake2: replace (4 times)
161         make genmake_tc_1.o >> genmake_warnings 2>&1
162      with
163         COMM="$CC $CFLAGS -c genmake_tc_1.c"
164         echo $COMM >> genmake_warnings
165         $COMM >> genmake_warnings 2>&1
166      to make genmake2 always see the value of CC as specified in the optfile.
167    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
168      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
169      - modify verification advect_cs test to test SOM-advection on CS-grid.
170    o pkg/ctrl:
171      - Rewrite of ctrl_map_ini_ecco.F,
172        introducing a generic routine (ctrl_map_ini_gen.F).
173      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
174    
175    checkpoint59n
176    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
177      number in dedicate array "hdiag":
178      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
179        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
180      - many small changes (integer format) for large number of diagnostics
181      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
182        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
183    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
184      usingSphericalGrid, this allows to define the rotated grid coordinates
185      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
186      geographical coordinates according to the inverse of the rotation defined
187      by the Euler angles, so that Coriolis parameter and online-interpolation by
188      exf works with the geographical coordinates on XC/YC/XG/YG.
189      Naturally, this feature does not work with all packages, so some
190      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
191      profiles), because there the coordinates are assumed to be regular
192      spherical grid coordinates.
193    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
194      - introduce isopycnal diffusion coefficient control.
195    o tools/adjoint_options:
196      - additional control vector components.
197    o pkg/mnc: have mnc create marginally meaning full coordinate variables
198      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
199    o pkg/mypackage:
200      - add example of read/write pickup for state-var ;
201      - add entry points to the main code for state-vars diags & write-pickup.
202    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
203      transitions for useExfYearlyFields
204      - add new subroutine that determines the file to read from for
205        use*YearlyFields = .TRUE. and .FALSE.
206      - add a verification experiment to global_with_exf that tests
207        useExfYearlyFields with USE_EXF_INTERPOLATION defined
208    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
209      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
210      subroutines (which could be generated from a template, because they are
211      almost identical), for now they are included in obcs_prescribe_read.F for
212      simplicity
213    o pkg/exf:
214      - add a little more diagnostic to exf_interp_read (in analogy to
215        mds_read_field, can be turned off with debugLevel < debugLevA=1)
216      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
217        ugly but fast by unrolling short inner loops, inserting a unroll=8
218        directive in routine lagran, and splitting a loop and making do while the
219        outermost loop (the latter requires the intoduction of index arrays)
220    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
221    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
222      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
223    o verification/seaice_obcs: updated for restart test and latest options
224    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
225      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
226      for now this is only available for the C-grid code and also within
227      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
228    
229    checkpoint59m
230    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
231      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
232    o gad_som : fix flux output (& diagnostics) to have same units as other  
233      advection scheme fluxes (was previously multiplied by deltaT).  
234    o added verification/seaice_obcs both to test seaice open boundaries
235      and to provide an example matlab scrpt for generating them
236    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
237    o pkg/salt_plume: clean up salt_plume_frac.F to
238      remove redundancy in PlumeMethod 1 and 4
239    o pkg/kpp: added saltplume diagnostics
240    o pkg/obcs and pkg/seaice:
241      - do not set uice and vice to zero when OB*icefile are unspecified
242      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
243      - moved seaice tracer obcs after call to seaice_growth
244    o pkg/salt_plume: added various options for salt plume depth
245      criterion and for vertical distribution of the salt
246    
247    checkpoint59l
248    o pkg/ptracers: new version of ptracers pickup:
249      read meta file and write only fields which are needed to restart.
250      ( same logic as main pickup file ; also using pickupStrictlyMatch )
251    o pkg/seaice:
252      - add timescale for melting due to warm mixed layer as a means of
253        setting SEAICE_availHeatFrac more conveniently
254      - add a CPP-flag/runtime parameter check for flooding algorithm
255      - reformulated availHeat in seaice_growth.F to be independent of AREA
256    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
257      unit changes
258    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
259    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
260      SX vector computer.
261    o pkg/seaice:
262      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
263        seaice forcing fields can now be read only through pkg/exf
264      - removed some unused halos
265    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
266    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
267      or U/VICE from U/VWIND before computing U/VSTRESS
268    
269    checkpoint59k
270    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
271      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
272    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
273      all experiments pass when compile with un-initialised var. checking option.
274    o added pkg/salt_plume
275    o script to test restart (for now, in MITgcm_contrib/jmc_script)
276    o pkg/seaice: new read/write pickup version.
277      read meta file and write only fields which are needed to restart.
278      ( same logic as main pickup file ; also using pickupStrictlyMatch )
279    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
280    o lab_sea.hb87: modify the domain & update output.hb87.txt :
281      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
282      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
283      process. Fixed here by closing the domain at the Northern boundary.
284    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
285    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
286      a set of consecutive levels in/from a 3-D array.
287    o pkg/ptracers:
288      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
289      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
290    
291    checkpoint59j
292    o in pkgs: dic, obcs, offline, rbcs:
293      standard way to compute coeff. for time interpolation between 2 time reccords
294      which retains full precision (& make results less dependent on compiler).
295      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
296    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
297      packages instead of reading ice cover and wind speed separately
298    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
299     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
300      to allow to compile customized code before the update)
301    o cleaning-up:
302      - fix CPP instruction syntax in pkg/obcs
303      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
304        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
305      - fix some threads issue in IO parts.
306    o pkg/dic:
307      - add tons of "_d 0" (--> much better testreports !)
308       and then update outputs of tutorial_global_oce_biogeo
309    o pkg/mom_fluxform:
310      add a special version of momentum advection intended to conserve momentum
311      next to a bathymetry step or a coastline edge. (default = off = #undef)
312    o new read/write pickup version:
313      - for now, only implemented for main (mdsio) pickup file.
314      - write out only what is needed to restart; merge pickup_nh , pickup_ph
315        and main pickup together.
316      - read meta file; read only what is needed to restart; stop if a field
317        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
318        if it make sense (even if the restart is not perfect).
319      - if no meta file, assume that pickup to read corresponds exactly to
320        a pickup that would currently be written.
321      - read pickup written in the old format (until checkpoint59i) if it
322        recognizes an old meta file (no field-list).
323      - add a meta file in exp. which starts from a pickup: 2 cases:
324        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
325         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
326        b) a meta file describing the content of the associated pickup file
327         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
328    o pkg/mdsio & pkg/rw:
329      - new routine to read a meta file ; new set of routine to read
330        Multiple-fields file (with meta file).
331    o added open boundary conditions capability for seaice
332        HSNOW, HSALT, UICE, and VICE
333    
334    checkpoint59i
335    o adjoint:
336      * fix multiDimAdvection adjoint
337        (partial recomputation problem by TAF for fVerT(:,:,kDown)
338        and comlev1 size definition (maxpass vs. max. number of tracers)
339      * verification/global_ocean.90x45x15 adjoint now tests
340        NLFS and multiDimAdvection using DST3 (=30)
341      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
342    o pkg/kpp: add "_d 0" to real constant (if missing);
343      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
344      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
345    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
346      for internal parameters related to restart process (formerly from PARAMS.h)
347      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
348    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
349      as argument. (only atm2d & obcs write_pickup have not yet been updated)
350    o pkg/monitor:
351      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
352      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
353      - account for deep Atmosphere factor and density factor (anelastic)
354    o added open boundary conditions capability for seaice HEFF and AREA
355    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
356      thermodynamics
357      - requires a little reorganization, which affects the testreport results
358        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
359        so that now the conservative form is tested
360      - add a few comments
361    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
362    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
363    o add new diagnostics to seaice: advective, diffusive fluxes (only for
364      multidim-advection, for scheme 2 they are not filled) and transports,
365      thermodynamic growth rates
366    o change units of EmPmR (inside the code, + within coupling interface)
367      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
368      Affects results @ truncation level (cg2d match) and update output of
369       experiments: lab_sea(6), global_ocean.90x40x15(10),
370      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
371      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
372      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
373      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
