4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o store 3-D (in-situ) density in commom block (DYNVARS.h)
8     - save 1 rho computation.
9     - no longer modify T & S inland when using down_slope pkg.
10    o gad_som : allow to switch to SOM advection for T & S without corresponding
11      pickup files (using new S/R: MDS_CHECK4FILE).
12    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
13      (for useSingleCpuIO to work in multi-threaded)
14    o pkg/shelfice:
15     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
16       with SHELFICEtopoFile in data.shelfice
17     - move code for reading ice shelf topography and modifying hFacC into separate
18       subroutines of the shelfice package
19     - separate initialisation of "fixed" and "variable" variables
20     - kTopC is not (yet) replaced by kSurfC, although this is possible
21    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
22    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
23      and rename:
24      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
25      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
26    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
27    
28    checkpoint61c
29    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
30      to add mass source/sink of fluid in the interior (3-D generalisation
31      of oceanic real-fresh water flux).
32    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
33    o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)
34    o new pkg: down_slope
35      density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
36      - presently, modify T & S inland (dwnslp_calc_rho.F).
37        can be avoided if rho was stored in common bloc and used in calc_phi_hyd.
38      - implementation for ocean in P-coords not tested.
39      - add secondary test to global_ocean.90x40x15 (input.dwnslp) to check this pkg.
40    o move kSurfC,kSurfW & kSurfS from SURFACE.h to GRID.h (next to kLowC)
41      (to facilitate conversion of oceanic pkg to p-coordinate).
42    o change FIND_RHO to FIND_RHO_2D :
43      pass arguments tFld & sFld as local (tile) 2D-arrays ; +fix EOS_CHECK.
44    o new pkg: cheapaml
45    
46    checkpoint61b
47    o exch2:
48      change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS)
49      - no longer depend on the order sequence (N,S,E,W).
50      - 3rd exchange no longer needed (tested with 24 tiles).
51      - same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff)
52      - exch_UV_A-grid readily available (but not yet tested).
53      comment out 3rd exch call and remove copy of V to U at SE & NE face-corners
54      (both are no longer needed) in exch_uv: no effect in forward run; but
55       get truncation error differences with adjoint exch.
56    o exch2:
57     - change index-bounds storage (moved from target to local tile,
58       more intuitive this way) ; rename/remove some variables.
59     - change utils/exch2/matlab-topology-generator & code_mods accordingly.
60    
61    checkpoint61a
62    o exch2/matlab-topology-generator:
63      fix bug in index bounds for N-S internal exchange (hard to tell if this
64      had any effect on the solution).
65    o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf
66      is exceeded
67    o testreport: modify syntax of awk, so that it works also with
68      awk, and not only with nawk and gawk
69    
70    checkpoint61
71    o autodiff
72      Change default for TAF usage by removing argument '-nonew_arg'
73      This changes TAF subroutine argument list (ordering of active var.)
74      Omission of this flag leads to incompatibility w.r.t. TAMC
75      To restore TAMC-compatibility, need following modifs:
76      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
77      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
78      Tested TAF version is 1.9.22
79      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
80    
81    checkpoint60
82    --->>> This is the last checkpoint for which generating the adjoint
83    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
84    --->>> by default.
85    --->>> Future checkpoints will ommit this flag by default.
86    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
87    o pkg/grdchk: Add gradient check to etan0 perturbations.
88    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
89    o pkg/autodiff: more flexibility in zeroadj.
90      model/src: modifying do_oceanic_phys.F accordingly.
91    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
92    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
93      special setup of gmredi for which the adjoint is stable
94      enough for parameter optimization.
95    o bridging the gap between eddy stress and GM.
96      -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
97          along with a change in CPP option (now ALLOW_EDDYPSI).
98      -> when using GM w/ GM_AdvForm:
99          The total eddy streamfunction (Psi = eddyPsi + K x Slope)
100          is applied either in the tracer Eq. or in momentum Eq.
101          depending on data.gmredi (intro. GM_InMomAsStress).
102      -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
103      The key modifications are in model/src/taueddy_external_forcing.F
104      pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F
105    
106    checkpoint59r
107    o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array
108      from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
109      fix option to read coriolis(@ cell-corner) from files with CS-grid.
110    o pkg/mnc: add some attributes to standard 1D-coordinate variables
111    o pkg/diagnostics: enforce missing_value attribute for scalar variables at
112      mass points, when using mnc for output
113      - add runtime parameter (missing_value, missing_value_int) to override
114        default (which is the value of getcon('UNDEF'))
115    o pkg/mnc: prepare mnc for the actual use of missing values with the
116      diagnostics package: small fix in mnc_cw_readwrite.template and more
117      initialisation of never used fields
118      - replace mnc_common.h and mnc_id_header.h with corresponding upper case
119      versions
120    o pkg/thsice/thsice_ini_vars.F added default initial values so that
121      thermodynamics sea ice solver does not blow up when some initial fields
122      are missing.
123    o move from external_forcing_surf.F to ini_forcing.F
124      the p-coord. hack consisting in using pLoad to set phi0surf ;
125      update output of tutorial_global_oce_in_p (affected @ truncation level).
126    o Freshen up a bit hs94.1x64x5, notably:
127      remove rotationPeriod and tRef=5*0. (adjoint only), and add
128      exactConserv=.TRUE.
129    o pkg/generic_advdiff:
130      change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only
131      applies to files where Temperature & Salinity 2nd Order moments are used.
132    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
133      this uses a dynamically allocated internal state data structure
134      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
135      and requires a fortran 90 compiler
136    
137    checkpoint59q
138    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
139       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
140    o Refresh tutorial_global_oce_biogeo, notably:
141      - change bathymetry (put back seamounts in ACC, use hFacs)
142      - change EOS (POLY3 --> JMD95Z)
143      - use Bryan-Lewis vertical diffusivity
144      - use multidimensional advection
145      - remove old virtual virtual in dic pkg, now done through ptracer pkg
146      - change a couple of parameters in dic pkg
147    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
148    o pkg/obcs: change default to OBCSfixTopo = .true.,
149      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
150      - replace "debugMode" with "debugLevel .GE. debLevB"
151    o implementation of TAF directives for gchem,cfc,dic
152    o remove "exp5" (replaced by tutorial_deep_convection).
153    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
154      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
155      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
156      --> changes results in exp4, seaice_obcs
157    o tutorial_deep_convection :
158      update the set-up and increase resolution and domain size ; start
159      from pseudo initial conditions = output at t=120mn in order to see
160      something happening when running testreport.
161    o pkg/seaice: add os7mp as an advection scheme
162                  add check for advection schemes
163                  add a flag for restoring T and S underneath sea ice
164    o pkg/my82: add netcdf-support and diagnostics
165    o thsice pkg:
166      - Now hsMax limits snow height by turning it into ice following
167        flooding scheme (and now conserving energy)
168      - Slight rewriting of the formula in thsice_calc_thick.F
169      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
170      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
171    
172    checkpoint59p
173    o gchem / dic / cfc :
174      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
175      - add new parameter files: "data.dic" & "data.cfc" ;
176      - various re-arrangement in initialisation & header file ;
177      - fix tutorial_global_oce_biogeo for multi-threaded test.
178    o pkg/dic: test for "pickup_dic" file when restarting ;
179      if no pickup-file, can restart with a re-initialised pH (same as it did
180      before) providing pickupStrictlyMatch is set to False.
181    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
182      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
183    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
184      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
185    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
186     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
187       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
188    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
189       scheme to use for vorticty-term ;
190     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
191       (with default selectVortScheme, return to original discretisation)
192     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
193    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
194    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
195      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
196      also fix diagnostics VISCAHW & VISCA4W.
197    
198    checkpoint59o
199    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
200    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
201      move a few statemens out the main loop into separate loops
202    o pkg/shelfice:
203      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
204        (kg/m^2/s), does not break tests, because in verification/isomip,
205        rhoConstFresh=rhoConst (by accident)
206      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
207      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
208        new file model/src/seawater.F, so that they are available for all pkgs.
209      - convert potential temperature into in-situ temperature. This changes the
210        isomip tests => update tests
211    o add a flag writePickupAtEnd (default=true) to be able to suppress
212      writing a pickup at the last timestep
213    o tools/mpack-1.6 :
214      - disable automake (not working) and autoconf (not needed).
215      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
216        also cleaner with much less compilation warnings.
217    o pkg/profiles:
218      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
219      (for "less than 32 characters name" compiler requirement)
220    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
221      conditions that have a different sampling frequency than S/T/U/V obcs
222    o pkg/diagnostics (stats-diags):
223      - fix global Min/Max in case 1 processor get only empty tiles
224    o genmake2: replace (4 times)
225         make genmake_tc_1.o >> genmake_warnings 2>&1
226      with
227         COMM="$CC $CFLAGS -c genmake_tc_1.c"
228         echo $COMM >> genmake_warnings
229         $COMM >> genmake_warnings 2>&1
230      to make genmake2 always see the value of CC as specified in the optfile.
231    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
232      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
233      - modify verification advect_cs test to test SOM-advection on CS-grid.
234    o pkg/ctrl:
235      - Rewrite of ctrl_map_ini_ecco.F,
236        introducing a generic routine (ctrl_map_ini_gen.F).
237      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
238    
239    checkpoint59n
240    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
241      number in dedicate array "hdiag":
242      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
243        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
244      - many small changes (integer format) for large number of diagnostics
245      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
246        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
247    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
248      usingSphericalGrid, this allows to define the rotated grid coordinates
249      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
250      geographical coordinates according to the inverse of the rotation defined
251      by the Euler angles, so that Coriolis parameter and online-interpolation by
252      exf works with the geographical coordinates on XC/YC/XG/YG.
253      Naturally, this feature does not work with all packages, so some
254      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
255      profiles), because there the coordinates are assumed to be regular
256      spherical grid coordinates.
257    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
258      - introduce isopycnal diffusion coefficient control.
259    o tools/adjoint_options:
260      - additional control vector components.
261    o pkg/mnc: have mnc create marginally meaning full coordinate variables
262      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
263    o pkg/mypackage:
264      - add example of read/write pickup for state-var ;
265      - add entry points to the main code for state-vars diags & write-pickup.
266    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
267      transitions for useExfYearlyFields
268      - add new subroutine that determines the file to read from for
269        use*YearlyFields = .TRUE. and .FALSE.
270      - add a verification experiment to global_with_exf that tests
271        useExfYearlyFields with USE_EXF_INTERPOLATION defined
272    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
273      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
274      subroutines (which could be generated from a template, because they are
275      almost identical), for now they are included in obcs_prescribe_read.F for
276      simplicity
277    o pkg/exf:
278      - add a little more diagnostic to exf_interp_read (in analogy to
279        mds_read_field, can be turned off with debugLevel < debugLevA=1)
280      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
281        ugly but fast by unrolling short inner loops, inserting a unroll=8
282        directive in routine lagran, and splitting a loop and making do while the
283        outermost loop (the latter requires the intoduction of index arrays)
284    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
285    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
286      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
287    o verification/seaice_obcs: updated for restart test and latest options
288    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
289      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
290      for now this is only available for the C-grid code and also within
291      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
292    
293    checkpoint59m
294    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
295      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
296    o gad_som : fix flux output (& diagnostics) to have same units as other  
297      advection scheme fluxes (was previously multiplied by deltaT).  
298    o added verification/seaice_obcs both to test seaice open boundaries
299      and to provide an example matlab scrpt for generating them
300    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
301    o pkg/salt_plume: clean up salt_plume_frac.F to
302      remove redundancy in PlumeMethod 1 and 4
303    o pkg/kpp: added saltplume diagnostics
304    o pkg/obcs and pkg/seaice:
305      - do not set uice and vice to zero when OB*icefile are unspecified
306      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
307      - moved seaice tracer obcs after call to seaice_growth
308    o pkg/salt_plume: added various options for salt plume depth
309      criterion and for vertical distribution of the salt
310    
311    checkpoint59l
312    o pkg/ptracers: new version of ptracers pickup:
313      read meta file and write only fields which are needed to restart.
314      ( same logic as main pickup file ; also using pickupStrictlyMatch )
315    o pkg/seaice:
316      - add timescale for melting due to warm mixed layer as a means of
317        setting SEAICE_availHeatFrac more conveniently
318      - add a CPP-flag/runtime parameter check for flooding algorithm
319      - reformulated availHeat in seaice_growth.F to be independent of AREA
320    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
321      unit changes
322    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
323    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
324      SX vector computer.
325    o pkg/seaice:
326      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
327        seaice forcing fields can now be read only through pkg/exf
328      - removed some unused halos
329    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
330    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
331      or U/VICE from U/VWIND before computing U/VSTRESS
332    
333    checkpoint59k
334    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
335      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
336    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
337      all experiments pass when compile with un-initialised var. checking option.
338    o added pkg/salt_plume
339    o script to test restart (for now, in MITgcm_contrib/jmc_script)
340    o pkg/seaice: new read/write pickup version.
341      read meta file and write only fields which are needed to restart.
342      ( same logic as main pickup file ; also using pickupStrictlyMatch )
343    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
344    o lab_sea.hb87: modify the domain & update output.hb87.txt :
345      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
346      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
347      process. Fixed here by closing the domain at the Northern boundary.
348    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
349    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
350      a set of consecutive levels in/from a 3-D array.
