7    checkpoint59d
8    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
9     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
10     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
11    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
12     and change default value of parameter "GM_Small_Number";
13     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
14       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
15       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
16    o pkg/ecco: cost function when applying pkg/smooth to controls
17    o pkg/ctrl: add forcingPrecond run time parameter
18    o pkg/seaice:
19     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
20     - fix bug in metric terms of u-equation in LSR solver (implicit part),
21       changes verification/lab_sea
22     - rearrange implicit part of u-equation in LSR solver to make it easier to
23       read, understand, and debug. This causes changes at the truncation level.
24     - fix (serious) bug in the boundary conditions (sign error in the implicit
25       part) of the LSR solver. Changes all LSR results.
26     - fixed problem with HSNOW initialization to avoid thick snow when AREA
27       is initilized with small values - does not change lab_sea results.
28     - added HsnowFile initialization capability
29    o pkg/smooth: addition to model/src and pkg/ctrl so allow
30     initialization of pkg/smooth and application to control vector
31    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
32    o dependencies: pkg/profiles requires pkg/cal
33    o pkg/profiles:
34     - added option ALLOW_PROFILES_GENERICGRID
35         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
36         that interpolation information (grid points and coefficients) is provided
37         within the netcdf input files.
38         -> sample matlab scripts can be found in MITgcm_contrib/gael
39         that allow you to prepare netcdf input files.
40     - also modified: cleaner include statements, cleaner error print statements,
41       cleaner stops when error, and more tests of the netcdf input files consistency.
42    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
43    o pkg/seaice:
44     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
45       requires a new routine: seaice_diagnostics_fill.F
46     - make sure that seaice does not move if not forced (pressure replacement
47       method, Hibler and Ip, 1995), changes results
48     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
49     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
50       It is turned off by default (=-1.), because it changes the results.
51     - make it possible to read AREA from a file, too.
52    
53    checkpoint59c
54    o add S/R and diagnostics for oceanic mixed-layer depth
55    o move GMRedi call after all vertical mixing schemes (including KPP)
56    o pkg/thsice:
57     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
58      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
