5      ==============================      ==============================
6    
7    o pkg/seaice: add diagnostics for snow precipitation
8    o eesupp/src:
9      new S/R with new option (NML_EXTENDED_F77) to change array specification
10      from F95 standard to commonly accepted extended F77 form.
11      This would allow to use F95 syntax in namelist (needed with gfortran 4.4.5)
12      and to revert back to the original syntax (with -DNML_EXTENDED_F77)
13      for less tolerant f77 compiler (e.g., pgf77, g77).
14    o globalFiles:
15      commented out in parameter file "data" since it's not safe with MPI
16      (e.g., wrong on aces); keep it if useSingleCpuIO=T (but not doing much
17      in this case); no longer commented out in restart test (tst_2+2).
18    o add adTapeDir to specify a special directory where adjoint tapes are
19      written/read (adread_adwrite.F). adTapeDir is specified in data/PARM05
20      and cannot be used together with mdsioLocalDir.
21    o nesting pkgs:
22      - packages_init_variables : put call to OBCS_INIT_VARIABLES in last position
23      - update Gianmaria's Nesting pkgs (from Contrib/nesting_sannino)
24      - add parameter files + utils dir + output from short run on beagle.
25    o pkg/seaice:
26        fix seaice_growth.F store directives; update results of exp. lab_sea.ad
27    o pkg/seaice: explicitly store tsurfloc in seaice_solve4temp.F to avoid
28      unnecessary copying in adjoint code, requires new parameter NMAX_ITER
29    
30    checkpoint62o (2010/11/25)
31    o pkg/exf:
32      - change CPP option EXF_VERBOSE to run-time logical param exf_verbose.
33    o pkg/seaice:
34      - seaice_ocean_stress: split a loop for better vectorization of the
35        adjoint code
36      - seaice_growth.F: fix bug in conservation of freshwater connected to
37        capping of heff, put contribution into d_HEFFbyNEG
38      - replace irritating parameters SEAICE_latentWater/Ice and SEAICE_sensHeat
39        by something more sensible (parameters that are what their name implies)
40      - change some defaults, so that by default exf-parameters are used for
41        things like rhoAir, cpAir,latent/sensible heat parameters, in order
42        to reproduce the old results, many data.seaice now contain funny values
43        for cpAir and latent heat of sublimation
44    o packages_readparms.F: move exf_readparms up in line so that
45        exf-parameters are visible for other packages (e.g. seaice)
46    o debugMode & debugLevel=2:
47      - differentiate between debugMode & debugLevel=2:
48        debugMode: controls printing of debug messages (sequence of S/R calls).
49        debugLevel: controls printing of algorithm intermediate results and stats.
50      - remove "if debugLevel=2 => debugMode" but keep "debugMode =>  debugLevel=2";
51        => allows to print debug-stats without all sequence of call messages.
52      - switch control of debug print from debugLevel to debugMode in many S/R.
53    o pkg/obcs (obcs-sponge):
54        fix bug that was introduced on Oct 25 (in dynamics.F v1.151): put back the
55        call to OBCS_PRESCRIBE_EXCHANGES (need to exch gU,gV when using obcs-sponge)
56    o pkg/generic_advdiff:
57      - record overlap minimum size for each advection scheme;
58      - refine criteria on overlap minimum size;
59      - check and stop (in gad_check) if overlap size is too small.
60    o pkg/obcs:
61      - with ptracers: remove multiple calls to obcs_apply_ptracer (only done
62        once, in ptracers_implicit.F)
63      - with seaice: remove test on empty file name in obcs_apply_seaice (always
64        apply OB values when tile has OB)
65    o model/src, coriolis setting:
66      - integer parameter "selectCoriMap" (=0,1,2) replaces 3 logical
67        useConstantF, useBetaPlaneF, useSphereF ; can now read coriolis from
68        files (selectCoriMap=3) with any grid.
69      - add parameter "fPrime" for constant second Coriolis coeff (default=0).
70    o pkg/seaice/seaice_growth.F:
71        a few cosmetic changes that reduce the number of lines of code
72    o pkg/obcs: add boundary conditions following Stevens (1990)
73      - the code follows old MOM/NAOSIM code
74      - so far it is only implemented for the eastern and western boundaries
75        and NOT for pTracers
76    o pkg/rbcs:
77      - replace rbcsInIter by rbcsForcingOffset, the time in seconds at the
78        beginning of the first rbcs forcing period.
79      - add option rbcsSingleTimeFiles that makes rbcs read forcing data like the
80        offline package, i.e., one file per time, labeled by iteration number;
81        deltaTrbcs sets the timestep with which the data was generated;
82        rbcsIter0 is the forcing iteration corresponding to rbcsForcingOffset.
83      - rbcsForcingCycle=0 makes forcing non-cyclic.
84      - make arithmetic safe for negative times and odd forcing periods.
85    
86    checkpoint62n (2010/11/09)
87    o pkg/seaice:
88        fix masking in free-drift S/R ; update results of exp. lab_sea.fd
89    o pkg/obcs:
90       New S/R to copy tracer value from the OB location to narrow band region
91        (width = same as overlap) beyond the OB: preserve OB value (needed for
92        high-order scheme) which were overwritten by EXCH call if in overlap
93        region. Applied to theta, salt, ptracer and advected seaice variables.
94       With seaice: use maskInC in similar way as in gad_advection.F,
95        in seaice_advection.F and advect.F.
96       Update output of experiment seaice_obcs and change exp4 to test OBCS with
97        4th order Adv.Scheme. for pasive salt and ptracer.
98    o tools/genmake2:
99      - when looking for an optfile (not specified), only search for Fortran compiler
100        (remove sym-link test + setting of CPP + makedepend check + C-compiler check)
101      - in get_fortran_c_namemangling: use "$CC $CFLAG" to compile C test programm
102        (instead of "$MAKE genmake_test.o" since an existing Makefile can be wrong)
103      - set default for CPP to "cpp -traditional -P" (was the case without specifying
104        an optfile, but otherwise default was just "cpp".
105      - comment out PLATFORM=$p_PLATFORM (no idea where p_PLATFORM comes from)
106      - when "CC" is not set in the optfile, look for possible C compiler
107        (instead of just setting CC=cc)
108      - put back version v.169 modif (from 2008/02/15), was dropped in v.173 changes:
109        => add a ".F" to ".o" rule for source files with no "#include" (such as
110           port_rand.F); otherwise, default ignores FOPTIM and just uses FFLAGS.
111      - move gfortran before g77 in list of possible Fortran compiler (consistent
112        with reference compiler switch from g77 to gfortran)
113    o pkg/seaice:
114      o remove SEAICE_OLD_AND_BAD_DISCRETIZATION-code, add a test to
115        seaice_check that stops the model, when the CPP flag is used.
116      o seaice_growth.F: make capping of ice volume conserving by returning the
117        capped ice as freshwater to EmPmR. This does not change the verification
118        experiments but will change runs where the capping is acutally active
119    o change reference platform+compiler from faulks+g77 to baudelaire+gfortran
120      (except the 2 fizhi test exp.); update output of exp.: bottom_ctrl_5x5,
121         global_ocean.cs32x15 (icedyn, thsice, AD thsice), global_ocean_ebm (AD),
122         lab_sea (fd, hb87, salt_plume), MLAdjust (3/5) and vermix (dd)
123    o tools/genmake2:
124      - merge genmake_warnings & genmake_errors into 1 log file: "genmake.log")
125      - change DUMPSTATE default to false (can use "-ds" option to switch it to T)
126      - clean previous genmake log files before anything else.
127      - change Makefile to remove testreport log files (*.tr_log) and genmake log
128        files only with "CLEAN" target (instead of "Clean");
129    o pkg/generic_advdiff:
130      Change OBCS in multiDim advection (gad_advection.F):
131       Use maskInC to prevent intermediate update of tracer-field in OB regions,
132       thus keeping current-time-step OB values; and remove the call to OBCS_APPLY
133       which were applying future time-step OB values.
134      This way, all explicit calculations use current-time-step OB values
135       (simpler and more consistent).
136      Affects results when set-up uses time-varying OBC and multi-dim advection;
137       update output of experiment seaice_obcs.
138    o pkg/seaice:
139      move OPTIONS (formerly locally defined) to SEAICE_OPTIONS.h:
140       this includes SEAICE_GROWTH_LEGACY (+ SEAICE_DO_OPEN_WATER_GROWTH &
141         SEAICE_OCN_MELT_ACT_ON_AREA ) and SEAICE_SOLVE4TEMP_LEGACY.
142      Default (pkg/seaice/SEAICE_OPTIONS.h) is to define SEAICE_SOLVE4TEMP_LEGACY
143       but leave SEAICE_GROWTH_LEGACY undef ; For now, keep verification exp
144       unchanged (SEAICE_GROWTH_LEGACY defined in */code*/SEAICE_OPTIONS.h)
145  o pkg aim (2010/10/26):  o pkg aim (2010/10/26):
146    - Introduce ALLOW_INSOLATION, moving toward a more general incoming solar radiation    - Introduce ALLOW_INSOLATION, moving toward a more general incoming solar radiation
147      formulation with obliquity, eccentricity, ... as run-time parameters,      formulation with obliquity, eccentricity, ... as run-time parameters,
148    - Introduce diagnostics for top-of-the-atmaophere incoming solar radiation and    - Introduce diagnostics for top-of-the-atmaophere incoming solar radiation and
149      upward shortwave radition at the surface (all-sky and clear-sky).      upward shortwave radition at the surface (all-sky and clear-sky).
   
150  o pkg/obcs:  o pkg/obcs:
151    - writing sections with globalFiles=T does not work: switch to tiled-files    - writing sections with globalFiles=T does not work: switch to tiled-files
152      when writing sections for OBCS (change pkg/rw/write_rec.F accordingly).      when writing sections for OBCS (change pkg/rw/write_rec.F accordingly).
