4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/seaice: add diagnostics for snow precipitation
8    o globalFiles:
9      commented out in parameter file "data" since it's not safe with MPI
10      (e.g., wrong on aces); keep it if useSingleCpuIO=T (but not doing much
11      in this case); no longer commented out in restart test (tst_2+2).
12    o add adTapeDir to specify a special directory where adjoint tapes are
13      written/read (adread_adwrite.F). adTapeDir is specified in data/PARM05
14      and cannot be used together with mdsioLocalDir.
15    o nesting pkgs:
16      - packages_init_variables : put call to OBCS_INIT_VARIABLES in last position
17      - update Gianmaria's Nesting pkgs (from Contrib/nesting_sannino)
18      - add parameter files + utils dir + output from short run on beagle.
19    o pkg/seaice:
20        fix seaice_growth.F store directives; update results of exp. lab_sea.ad
21    o pkg/seaice: explicitly store tsurfloc in seaice_solve4temp.F to avoid
22      unnecessary copying in adjoint code, requires new parameter NMAX_ITER
23    
24    checkpoint62o (2010/11/25)
25    o pkg/exf:
26      - change CPP option EXF_VERBOSE to run-time logical param exf_verbose.
27    o pkg/seaice:
28      - seaice_ocean_stress: split a loop for better vectorization of the
29        adjoint code
30      - seaice_growth.F: fix bug in conservation of freshwater connected to
31        capping of heff, put contribution into d_HEFFbyNEG
32      - replace irritating parameters SEAICE_latentWater/Ice and SEAICE_sensHeat
33        by something more sensible (parameters that are what their name implies)
34      - change some defaults, so that by default exf-parameters are used for
35        things like rhoAir, cpAir,latent/sensible heat parameters, in order
36        to reproduce the old results, many data.seaice now contain funny values
37        for cpAir and latent heat of sublimation
38    o packages_readparms.F: move exf_readparms up in line so that
39        exf-parameters are visible for other packages (e.g. seaice)
40    o debugMode & debugLevel=2:
41      - differentiate between debugMode & debugLevel=2:
42        debugMode: controls printing of debug messages (sequence of S/R calls).
43        debugLevel: controls printing of algorithm intermediate results and stats.
44      - remove "if debugLevel=2 => debugMode" but keep "debugMode =>  debugLevel=2";
45        => allows to print debug-stats without all sequence of call messages.
46      - switch control of debug print from debugLevel to debugMode in many S/R.
47    o pkg/obcs (obcs-sponge):
48        fix bug that was introduced on Oct 25 (in dynamics.F v1.151): put back the
49        call to OBCS_PRESCRIBE_EXCHANGES (need to exch gU,gV when using obcs-sponge)
50    o pkg/generic_advdiff:
51      - record overlap minimum size for each advection scheme;
52      - refine criteria on overlap minimum size;
53      - check and stop (in gad_check) if overlap size is too small.
54    o pkg/obcs:
55      - with ptracers: remove multiple calls to obcs_apply_ptracer (only done
56        once, in ptracers_implicit.F)
57      - with seaice: remove test on empty file name in obcs_apply_seaice (always
58        apply OB values when tile has OB)
59    o model/src, coriolis setting:
60      - integer parameter "selectCoriMap" (=0,1,2) replaces 3 logical
61        useConstantF, useBetaPlaneF, useSphereF ; can now read coriolis from
62        files (selectCoriMap=3) with any grid.
63      - add parameter "fPrime" for constant second Coriolis coeff (default=0).
64    o pkg/seaice/seaice_growth.F:
65        a few cosmetic changes that reduce the number of lines of code
66    o pkg/obcs: add boundary conditions following Stevens (1990)
67      - the code follows old MOM/NAOSIM code
68      - so far it is only implemented for the eastern and western boundaries
69        and NOT for pTracers
70    o pkg/rbcs:
71      - replace rbcsInIter by rbcsForcingOffset, the time in seconds at the
72        beginning of the first rbcs forcing period.
73      - add option rbcsSingleTimeFiles that makes rbcs read forcing data like the
74        offline package, i.e., one file per time, labeled by iteration number;
75        deltaTrbcs sets the timestep with which the data was generated;
76        rbcsIter0 is the forcing iteration corresponding to rbcsForcingOffset.
77      - rbcsForcingCycle=0 makes forcing non-cyclic.
78      - make arithmetic safe for negative times and odd forcing periods.
79    
80    checkpoint62n (2010/11/09)
81    o pkg/seaice:
82        fix masking in free-drift S/R ; update results of exp. lab_sea.fd
83    o pkg/obcs:
84       New S/R to copy tracer value from the OB location to narrow band region
85        (width = same as overlap) beyond the OB: preserve OB value (needed for
86        high-order scheme) which were overwritten by EXCH call if in overlap
87        region. Applied to theta, salt, ptracer and advected seaice variables.
88       With seaice: use maskInC in similar way as in gad_advection.F,
89        in seaice_advection.F and advect.F.
90       Update output of experiment seaice_obcs and change exp4 to test OBCS with
91        4th order Adv.Scheme. for pasive salt and ptracer.
92    o tools/genmake2:
93      - when looking for an optfile (not specified), only search for Fortran compiler
94        (remove sym-link test + setting of CPP + makedepend check + C-compiler check)
95      - in get_fortran_c_namemangling: use "$CC $CFLAG" to compile C test programm
96        (instead of "$MAKE genmake_test.o" since an existing Makefile can be wrong)
97      - set default for CPP to "cpp -traditional -P" (was the case without specifying
98        an optfile, but otherwise default was just "cpp".
99      - comment out PLATFORM=$p_PLATFORM (no idea where p_PLATFORM comes from)
100      - when "CC" is not set in the optfile, look for possible C compiler
101        (instead of just setting CC=cc)
102      - put back version v.169 modif (from 2008/02/15), was dropped in v.173 changes:
103        => add a ".F" to ".o" rule for source files with no "#include" (such as
104           port_rand.F); otherwise, default ignores FOPTIM and just uses FFLAGS.
105      - move gfortran before g77 in list of possible Fortran compiler (consistent
106        with reference compiler switch from g77 to gfortran)
107    o pkg/seaice:
108      o remove SEAICE_OLD_AND_BAD_DISCRETIZATION-code, add a test to
109        seaice_check that stops the model, when the CPP flag is used.
110      o seaice_growth.F: make capping of ice volume conserving by returning the
111        capped ice as freshwater to EmPmR. This does not change the verification
112        experiments but will change runs where the capping is acutally active
113    o change reference platform+compiler from faulks+g77 to baudelaire+gfortran
114      (except the 2 fizhi test exp.); update output of exp.: bottom_ctrl_5x5,
115         global_ocean.cs32x15 (icedyn, thsice, AD thsice), global_ocean_ebm (AD),
116         lab_sea (fd, hb87, salt_plume), MLAdjust (3/5) and vermix (dd)
117    o tools/genmake2:
118      - merge genmake_warnings & genmake_errors into 1 log file: "genmake.log")
119      - change DUMPSTATE default to false (can use "-ds" option to switch it to T)
120      - clean previous genmake log files before anything else.
121      - change Makefile to remove testreport log files (*.tr_log) and genmake log
122        files only with "CLEAN" target (instead of "Clean");
123    o pkg/generic_advdiff:
124      Change OBCS in multiDim advection (gad_advection.F):
125       Use maskInC to prevent intermediate update of tracer-field in OB regions,
126       thus keeping current-time-step OB values; and remove the call to OBCS_APPLY
127       which were applying future time-step OB values.
128      This way, all explicit calculations use current-time-step OB values
129       (simpler and more consistent).
130      Affects results when set-up uses time-varying OBC and multi-dim advection;
131       update output of experiment seaice_obcs.
132    o pkg/seaice:
133      move OPTIONS (formerly locally defined) to SEAICE_OPTIONS.h:
134       this includes SEAICE_GROWTH_LEGACY (+ SEAICE_DO_OPEN_WATER_GROWTH &
135         SEAICE_OCN_MELT_ACT_ON_AREA ) and SEAICE_SOLVE4TEMP_LEGACY.
136      Default (pkg/seaice/SEAICE_OPTIONS.h) is to define SEAICE_SOLVE4TEMP_LEGACY
137       but leave SEAICE_GROWTH_LEGACY undef ; For now, keep verification exp
138       unchanged (SEAICE_GROWTH_LEGACY defined in */code*/SEAICE_OPTIONS.h)
139  o pkg aim (2010/10/26):  o pkg aim (2010/10/26):
140    - Introduce ALLOW_INSOLATION, moving toward a more general incoming solar radiation    - Introduce ALLOW_INSOLATION, moving toward a more general incoming solar radiation
141      formulation with obliquity, eccentricity, ... as run-time parameters,      formulation with obliquity, eccentricity, ... as run-time parameters,
142    - Introduce diagnostics for top-of-the-atmaophere incoming solar radiation and    - Introduce diagnostics for top-of-the-atmaophere incoming solar radiation and
143      upward shortwave radition at the surface (all-sky and clear-sky).      upward shortwave radition at the surface (all-sky and clear-sky).
   
144  o pkg/obcs:  o pkg/obcs:
145    - writing sections with globalFiles=T does not work: switch to tiled-files    - writing sections with globalFiles=T does not work: switch to tiled-files
146      when writing sections for OBCS (change pkg/rw/write_rec.F accordingly).      when writing sections for OBCS (change pkg/rw/write_rec.F accordingly).
