4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/obcs: add boundary conditions following Stevens (1990)
8      - the code follows old MOM/NAOSIM code
9      - so far it is only implemented for the eastern and western boundaries
10        and NOT for pTracers
11    o pkg/rbcs:
12      - replace rbcsInIter by rbcsForcingOffset, the time in seconds at the
13        beginning of the first rbcs forcing period.
14      - add option rbcsSingleTimeFiles that makes rbcs read forcing data like the
15        offline package, i.e., one file per time, labeled by iteration number;
16        deltaTrbcs sets the timestep with which the data was generated;
17        rbcsIter0 is the forcing iteration corresponding to rbcsForcingOffset.
18      - rbcsForcingCycle=0 makes forcing non-cyclic.
19      - make arithmetic safe for negative times and odd forcing periods.

21    checkpoint62n (2010/11/09)
22    o pkg/seaice:
23        fix masking in free-drift S/R ; update results of exp. lab_sea.fd
24    o pkg/obcs:
25       New S/R to copy tracer value from the OB location to narrow band region
26        (width = same as overlap) beyond the OB: preserve OB value (needed for
27        high-order scheme) which were overwritten by EXCH call if in overlap
28        region. Applied to theta, salt, ptracer and advected seaice variables.
29       With seaice: use maskInC in similar way as in gad_advection.F,
30        in seaice_advection.F and advect.F.
31       Update output of experiment seaice_obcs and change exp4 to test OBCS with
32        4th order Adv.Scheme. for pasive salt and ptracer.
33    o tools/genmake2:
34      - when looking for an optfile (not specified), only search for Fortran compiler
35        (remove sym-link test + setting of CPP + makedepend check + C-compiler check)
36      - in get_fortran_c_namemangling: use "$CC $CFLAG" to compile C test programm
37        (instead of "$MAKE genmake_test.o" since an existing Makefile can be wrong)
38      - set default for CPP to "cpp -traditional -P" (was the case without specifying
39        an optfile, but otherwise default was just "cpp".
40      - comment out PLATFORM=$p_PLATFORM (no idea where p_PLATFORM comes from)
41      - when "CC" is not set in the optfile, look for possible C compiler
42        (instead of just setting CC=cc)
43      - put back version v.169 modif (from 2008/02/15), was dropped in v.173 changes:
44        => add a ".F" to ".o" rule for source files with no "#include" (such as
45           port_rand.F); otherwise, default ignores FOPTIM and just uses FFLAGS.
46      - move gfortran before g77 in list of possible Fortran compiler (consistent
47        with reference compiler switch from g77 to gfortran)
48    o pkg/seaice:
49      o remove SEAICE_OLD_AND_BAD_DISCRETIZATION-code, add a test to
50        seaice_check that stops the model, when the CPP flag is used.
51      o seaice_growth.F: make capping of ice volume conserving by returning the
52        capped ice as freshwater to EmPmR. This does not change the verification
53        experiments but will change runs where the capping is acutally active
54    o change reference platform+compiler from faulks+g77 to baudelaire+gfortran
55      (except the 2 fizhi test exp.); update output of exp.: bottom_ctrl_5x5,
56         global_ocean.cs32x15 (icedyn, thsice, AD thsice), global_ocean_ebm (AD),
57         lab_sea (fd, hb87, salt_plume), MLAdjust (3/5) and vermix (dd)
58    o tools/genmake2:
59      - merge genmake_warnings & genmake_errors into 1 log file: "genmake.log")
60      - change DUMPSTATE default to false (can use "-ds" option to switch it to T)
61      - clean previous genmake log files before anything else.
62      - change Makefile to remove testreport log files (*.tr_log) and genmake log
63        files only with "CLEAN" target (instead of "Clean");
64    o pkg/generic_advdiff:
65      Change OBCS in multiDim advection (gad_advection.F):
66       Use maskInC to prevent intermediate update of tracer-field in OB regions,
67       thus keeping current-time-step OB values; and remove the call to OBCS_APPLY
68       which were applying future time-step OB values.
69      This way, all explicit calculations use current-time-step OB values
70       (simpler and more consistent).
71      Affects results when set-up uses time-varying OBC and multi-dim advection;
72       update output of experiment seaice_obcs.
73    o pkg/seaice:
74      move OPTIONS (formerly locally defined) to SEAICE_OPTIONS.h:
75       this includes SEAICE_GROWTH_LEGACY (+ SEAICE_DO_OPEN_WATER_GROWTH &
76         SEAICE_OCN_MELT_ACT_ON_AREA ) and SEAICE_SOLVE4TEMP_LEGACY.
77      Default (pkg/seaice/SEAICE_OPTIONS.h) is to define SEAICE_SOLVE4TEMP_LEGACY
78       but leave SEAICE_GROWTH_LEGACY undef ; For now, keep verification exp
79       unchanged (SEAICE_GROWTH_LEGACY defined in */code*/SEAICE_OPTIONS.h)
80    o pkg aim (2010/10/26):
81      - Introduce ALLOW_INSOLATION, moving toward a more general incoming solar radiation
82        formulation with obliquity, eccentricity, ... as run-time parameters,
83      - Introduce diagnostics for top-of-the-atmaophere incoming solar radiation and
84        upward shortwave radition at the surface (all-sky and clear-sky).
85    o pkg/obcs:
86      - writing sections with globalFiles=T does not work: switch to tiled-files
87        when writing sections for OBCS (change pkg/rw/write_rec.F accordingly).
88      - fix index bug (OB_Ie -> OB_Iw_) in obcs_apply_uvice.F
89      - apply OBCS_SEAICE_COMPUTE_UVICE to both uice and vice at all obcs
90    
91    checkpoint62m (2010/10/21)
92    o pkg/seaice: vectorize seaice_solve4temp.F
93      - move iterations loops outside of i/j-loops
94      - requires 2D arrays for TB and effConduct
95      - add 2D iceOrNot to replace HICE_ACTUAL.GT.0, as HICE_ACTUAL is
96        modified in this routine
97      - a little bit of clean up, adjusting indentation, etc.
98      - replaced a few TEN**a by exp(a*log(10.)) in new code for better
99        performance and '**TWO' by '**2' (because TWO is a float),
100        replaced ONE, ZERO
