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