4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o new pkg: down_slope
8      density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
9      - presently, modify T & S inland (dwnslp_calc_rho.F).
10        can be avoided if rho was stored in common bloc and used in calc_phi_hyd.
11      - implementation for ocean in P-coords not tested.
12      - add secondary test to global_ocean.90x40x15 (input.dwnslp) to check this pkg.
13    o move kSurfC,kSurfW & kSurfS from SURFACE.h to GRID.h (next to kLowC)
14      (to facilitate conversion of oceanic pkg to p-coordinate).
15    o change FIND_RHO to FIND_RHO_2D :
16      pass arguments tFld & sFld as local (tile) 2D-arrays ; +fix EOS_CHECK.
17    o new pkg: cheapaml
18    
19    checkpoint61b
20    o exch2:
21      change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS)
22      - no longer depend on the order sequence (N,S,E,W).
23      - 3rd exchange no longer needed (tested with 24 tiles).
24      - same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff)
25      - exch_UV_A-grid readily available (but not yet tested).
26      comment out 3rd exch call and remove copy of V to U at SE & NE face-corners
27      (both are no longer needed) in exch_uv: no effect in forward run; but
28       get truncation error differences with adjoint exch.
29    o exch2:
30     - change index-bounds storage (moved from target to local tile,
31       more intuitive this way) ; rename/remove some variables.
32     - change utils/exch2/matlab-topology-generator & code_mods accordingly.
33    
34    checkpoint61a
35    o exch2/matlab-topology-generator:
36      fix bug in index bounds for N-S internal exchange (hard to tell if this
37      had any effect on the solution).
38    o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf
39      is exceeded
40    o testreport: modify syntax of awk, so that it works also with
41      awk, and not only with nawk and gawk
42    
43    checkpoint61
44    o autodiff
45      Change default for TAF usage by removing argument '-nonew_arg'
46      This changes TAF subroutine argument list (ordering of active var.)
47      Omission of this flag leads to incompatibility w.r.t. TAMC
48      To restore TAMC-compatibility, need following modifs:
49      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
50      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
51      Tested TAF version is 1.9.22
52      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
53    
54    checkpoint60
55    --->>> This is the last checkpoint for which generating the adjoint
56    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
57    --->>> by default.
58    --->>> Future checkpoints will ommit this flag by default.
59    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
60    o pkg/grdchk: Add gradient check to etan0 perturbations.
61    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
62    o pkg/autodiff: more flexibility in zeroadj.
63      model/src: modifying do_oceanic_phys.F accordingly.
64    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
65    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
66      special setup of gmredi for which the adjoint is stable
67      enough for parameter optimization.
68    o bridging the gap between eddy stress and GM.
69      -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
70          along with a change in CPP option (now ALLOW_EDDYPSI).
71      -> when using GM w/ GM_AdvForm:
72          The total eddy streamfunction (Psi = eddyPsi + K x Slope)
73          is applied either in the tracer Eq. or in momentum Eq.
74          depending on data.gmredi (intro. GM_InMomAsStress).
75      -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
76      The key modifications are in model/src/taueddy_external_forcing.F
77      pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F
78    
79    checkpoint59r
80    o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array
81      from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
82      fix option to read coriolis(@ cell-corner) from files with CS-grid.
83    o pkg/mnc: add some attributes to standard 1D-coordinate variables
84    o pkg/diagnostics: enforce missing_value attribute for scalar variables at
85      mass points, when using mnc for output
86      - add runtime parameter (missing_value, missing_value_int) to override
87        default (which is the value of getcon('UNDEF'))
88    o pkg/mnc: prepare mnc for the actual use of missing values with the
89      diagnostics package: small fix in mnc_cw_readwrite.template and more
90      initialisation of never used fields
91      - replace mnc_common.h and mnc_id_header.h with corresponding upper case
92      versions
93    o pkg/thsice/thsice_ini_vars.F added default initial values so that
94      thermodynamics sea ice solver does not blow up when some initial fields
95      are missing.
96    o move from external_forcing_surf.F to ini_forcing.F
97      the p-coord. hack consisting in using pLoad to set phi0surf ;
98      update output of tutorial_global_oce_in_p (affected @ truncation level).
99    o Freshen up a bit hs94.1x64x5, notably:
100      remove rotationPeriod and tRef=5*0. (adjoint only), and add
101      exactConserv=.TRUE.
102    o pkg/generic_advdiff:
103      change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only
104      applies to files where Temperature & Salinity 2nd Order moments are used.
105    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
106      this uses a dynamically allocated internal state data structure
107      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
108      and requires a fortran 90 compiler
109    
110    checkpoint59q
111    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
112       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
113    o Refresh tutorial_global_oce_biogeo, notably:
114      - change bathymetry (put back seamounts in ACC, use hFacs)
115      - change EOS (POLY3 --> JMD95Z)
116      - use Bryan-Lewis vertical diffusivity
117      - use multidimensional advection
118      - remove old virtual virtual in dic pkg, now done through ptracer pkg
119      - change a couple of parameters in dic pkg
120    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
121    o pkg/obcs: change default to OBCSfixTopo = .true.,
122      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
123      - replace "debugMode" with "debugLevel .GE. debLevB"
124    o implementation of TAF directives for gchem,cfc,dic
125    o remove "exp5" (replaced by tutorial_deep_convection).
126    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
127      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
128      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
129      --> changes results in exp4, seaice_obcs
130    o tutorial_deep_convection :
131      update the set-up and increase resolution and domain size ; start
132      from pseudo initial conditions = output at t=120mn in order to see
133      something happening when running testreport.
134    o pkg/seaice: add os7mp as an advection scheme
135                  add check for advection schemes
136                  add a flag for restoring T and S underneath sea ice
137    o pkg/my82: add netcdf-support and diagnostics
138    o thsice pkg:
139      - Now hsMax limits snow height by turning it into ice following
140        flooding scheme (and now conserving energy)
141      - Slight rewriting of the formula in thsice_calc_thick.F
142      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
143      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
144    
145    checkpoint59p
146    o gchem / dic / cfc :
147      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
148      - add new parameter files: "data.dic" & "data.cfc" ;
149      - various re-arrangement in initialisation & header file ;
150      - fix tutorial_global_oce_biogeo for multi-threaded test.
151    o pkg/dic: test for "pickup_dic" file when restarting ;
152      if no pickup-file, can restart with a re-initialised pH (same as it did
153      before) providing pickupStrictlyMatch is set to False.
154    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
155      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
156    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
157      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
158    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
159     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
160       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
161    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
162       scheme to use for vorticty-term ;
163     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
164       (with default selectVortScheme, return to original discretisation)
165     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
166    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
167    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
168      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
169      also fix diagnostics VISCAHW & VISCA4W.
170    
171    checkpoint59o
172    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
173    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
174      move a few statemens out the main loop into separate loops
175    o pkg/shelfice:
176      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
177        (kg/m^2/s), does not break tests, because in verification/isomip,
178        rhoConstFresh=rhoConst (by accident)
179      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
180      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
181        new file model/src/seawater.F, so that they are available for all pkgs.
182      - convert potential temperature into in-situ temperature. This changes the
183        isomip tests => update tests
184    o add a flag writePickupAtEnd (default=true) to be able to suppress
185      writing a pickup at the last timestep
186    o tools/mpack-1.6 :
187      - disable automake (not working) and autoconf (not needed).
188      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
189        also cleaner with much less compilation warnings.
190    o pkg/profiles:
191      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
192      (for "less than 32 characters name" compiler requirement)
193    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
194      conditions that have a different sampling frequency than S/T/U/V obcs
195    o pkg/diagnostics (stats-diags):
196      - fix global Min/Max in case 1 processor get only empty tiles
197    o genmake2: replace (4 times)
198         make genmake_tc_1.o >> genmake_warnings 2>&1
199      with
200         COMM="$CC $CFLAGS -c genmake_tc_1.c"
201         echo $COMM >> genmake_warnings
202         $COMM >> genmake_warnings 2>&1
203      to make genmake2 always see the value of CC as specified in the optfile.
204    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
205      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
206      - modify verification advect_cs test to test SOM-advection on CS-grid.
207    o pkg/ctrl:
208      - Rewrite of ctrl_map_ini_ecco.F,
209        introducing a generic routine (ctrl_map_ini_gen.F).
210      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
211    
212    checkpoint59n
213    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
214      number in dedicate array "hdiag":
215      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
216        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
217      - many small changes (integer format) for large number of diagnostics
218      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
219        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
220    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
221      usingSphericalGrid, this allows to define the rotated grid coordinates
222      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
223      geographical coordinates according to the inverse of the rotation defined
224      by the Euler angles, so that Coriolis parameter and online-interpolation by
225      exf works with the geographical coordinates on XC/YC/XG/YG.
226      Naturally, this feature does not work with all packages, so some
227      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
228      profiles), because there the coordinates are assumed to be regular
229      spherical grid coordinates.
230    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
231      - introduce isopycnal diffusion coefficient control.
232    o tools/adjoint_options:
233      - additional control vector components.
234    o pkg/mnc: have mnc create marginally meaning full coordinate variables
235      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
236    o pkg/mypackage:
237      - add example of read/write pickup for state-var ;
238      - add entry points to the main code for state-vars diags & write-pickup.
239    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
240      transitions for useExfYearlyFields
241      - add new subroutine that determines the file to read from for
242        use*YearlyFields = .TRUE. and .FALSE.
243      - add a verification experiment to global_with_exf that tests
244        useExfYearlyFields with USE_EXF_INTERPOLATION defined
245    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
246      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
247      subroutines (which could be generated from a template, because they are
248      almost identical), for now they are included in obcs_prescribe_read.F for
249      simplicity
250    o pkg/exf:
251      - add a little more diagnostic to exf_interp_read (in analogy to
252        mds_read_field, can be turned off with debugLevel < debugLevA=1)
253      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
254        ugly but fast by unrolling short inner loops, inserting a unroll=8
255        directive in routine lagran, and splitting a loop and making do while the
256        outermost loop (the latter requires the intoduction of index arrays)
257    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
258    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
259      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
260    o verification/seaice_obcs: updated for restart test and latest options
261    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
262      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
263      for now this is only available for the C-grid code and also within
264      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
265    
266    checkpoint59m
267    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
268      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
269    o gad_som : fix flux output (& diagnostics) to have same units as other  
270      advection scheme fluxes (was previously multiplied by deltaT).  
271    o added verification/seaice_obcs both to test seaice open boundaries
272      and to provide an example matlab scrpt for generating them
273    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
274    o pkg/salt_plume: clean up salt_plume_frac.F to
275      remove redundancy in PlumeMethod 1 and 4
276    o pkg/kpp: added saltplume diagnostics
277    o pkg/obcs and pkg/seaice:
278      - do not set uice and vice to zero when OB*icefile are unspecified
279      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
280      - moved seaice tracer obcs after call to seaice_growth
281    o pkg/salt_plume: added various options for salt plume depth
282      criterion and for vertical distribution of the salt
283    
284    checkpoint59l
285    o pkg/ptracers: new version of ptracers pickup:
286      read meta file and write only fields which are needed to restart.
287      ( same logic as main pickup file ; also using pickupStrictlyMatch )
288    o pkg/seaice:
289      - add timescale for melting due to warm mixed layer as a means of
290        setting SEAICE_availHeatFrac more conveniently
291      - add a CPP-flag/runtime parameter check for flooding algorithm
292      - reformulated availHeat in seaice_growth.F to be independent of AREA
293    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
294      unit changes
295    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
296    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
297      SX vector computer.
298    o pkg/seaice:
299      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
300        seaice forcing fields can now be read only through pkg/exf
301      - removed some unused halos
302    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
303    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
304      or U/VICE from U/VWIND before computing U/VSTRESS
305    
306    checkpoint59k
307    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
308      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
309    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
310      all experiments pass when compile with un-initialised var. checking option.
311    o added pkg/salt_plume
312  o script to test restart (for now, in MITgcm_contrib/jmc_script)  o script to test restart (for now, in MITgcm_contrib/jmc_script)
313  o pkg/seaice: new read/write pickup version.  o pkg/seaice: new read/write pickup version.
314    read meta file and write only fields which are needed to restart.    read meta file and write only fields which are needed to restart.
