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

24    o pkg/seaice:
25        fix masking in free-drift S/R ; update results of exp. lab_sea.fd
26    o pkg/obcs:
27       New S/R to copy tracer value from the OB location to narrow band region
28        (width = same as overlap) beyond the OB: preserve OB value (needed for
29        high-order scheme) which were overwritten by EXCH call if in overlap
30        region. Applied to theta, salt, ptracer and advected seaice variables.
31       With seaice: use maskInC in similar way as in gad_advection.F,
32        in seaice_advection.F and advect.F.
33       Update output of experiment seaice_obcs and change exp4 to test OBCS with
34        4th order Adv.Scheme. for pasive salt and ptracer.
35    o tools/genmake2:
36      - when looking for an optfile (not specified), only search for Fortran compiler
37        (remove sym-link test + setting of CPP + makedepend check + C-compiler check)
38      - in get_fortran_c_namemangling: use "$CC $CFLAG" to compile C test programm
39        (instead of "$MAKE genmake_test.o" since an existing Makefile can be wrong)
40      - set default for CPP to "cpp -traditional -P" (was the case without specifying
41        an optfile, but otherwise default was just "cpp".
42      - comment out PLATFORM=$p_PLATFORM (no idea where p_PLATFORM comes from)
43      - when "CC" is not set in the optfile, look for possible C compiler
44        (instead of just setting CC=cc)
45      - put back version v.169 modif (from 2008/02/15), was dropped in v.173 changes:
46        => add a ".F" to ".o" rule for source files with no "#include" (such as
47           port_rand.F); otherwise, default ignores FOPTIM and just uses FFLAGS.
48      - move gfortran before g77 in list of possible Fortran compiler (consistent
49        with reference compiler switch from g77 to gfortran)
50    o pkg/seaice:
51      o remove SEAICE_OLD_AND_BAD_DISCRETIZATION-code, add a test to
52        seaice_check that stops the model, when the CPP flag is used.
53      o seaice_growth.F: make capping of ice volume conserving by returning the
54        capped ice as freshwater to EmPmR. This does not change the verification
55        experiments but will change runs where the capping is acutally active
56    o change reference platform+compiler from faulks+g77 to baudelaire+gfortran
57      (except the 2 fizhi test exp.); update output of exp.: bottom_ctrl_5x5,
58         global_ocean.cs32x15 (icedyn, thsice, AD thsice), global_ocean_ebm (AD),
59         lab_sea (fd, hb87, salt_plume), MLAdjust (3/5) and vermix (dd)
60    o tools/genmake2:
61      - merge genmake_warnings & genmake_errors into 1 log file: "genmake.log")
62      - change DUMPSTATE default to false (can use "-ds" option to switch it to T)
63      - clean previous genmake log files before anything else.
64      - change Makefile to remove testreport log files (*.tr_log) and genmake log
65        files only with "CLEAN" target (instead of "Clean");
66    o pkg/generic_advdiff:
67      Change OBCS in multiDim advection (gad_advection.F):
68       Use maskInC to prevent intermediate update of tracer-field in OB regions,
69       thus keeping current-time-step OB values; and remove the call to OBCS_APPLY
70       which were applying future time-step OB values.
71      This way, all explicit calculations use current-time-step OB values
72       (simpler and more consistent).
73      Affects results when set-up uses time-varying OBC and multi-dim advection;
74       update output of experiment seaice_obcs.
75  o pkg/seaice:  o pkg/seaice:
76    move OPTIONS (formerly locally defined) to SEAICE_OPTIONS.h:    move OPTIONS (formerly locally defined) to SEAICE_OPTIONS.h:
77     this includes SEAICE_GROWTH_LEGACY (+ SEAICE_DO_OPEN_WATER_GROWTH &     this includes SEAICE_GROWTH_LEGACY (+ SEAICE_DO_OPEN_WATER_GROWTH &
