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