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