5      ==============================      ==============================
6    
7    o dependencies: pkg/profiles requires pkg/cal
8    o pkg/profiles:
9     - added option ALLOW_PROFILES_GENERICGRID
10         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
11         that interpolation information (grid points and coefficients) is provided
12         within the netcdf input files.
13         -> sample matlab scripts can be found in MITgcm_contrib/gael
14         that allow you to prepare netcdf input files.
15     - also modified: cleaner include statements, cleaner error print statements,
16       cleaner stops when error, and more tests of the netcdf input files consistency.
17    
18    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
19    o pkg/seaice:
20     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
21       requires a new routine: seaice_diagnostics_fill.F
22     - make sure that seaice does not move if not forced (pressure replacement
23       method, Hibler and Ip, 1995), changes results
24     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
25     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
26       It is turned off by default (=-1.), because it changes the results.
27     - make it possible to read AREA from a file, too.
28    
29    checkpoint59c
30    o add S/R and diagnostics for oceanic mixed-layer depth
31    o move GMRedi call after all vertical mixing schemes (including KPP)
32    o pkg/thsice:
33     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
34      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
35  o pkg/obcs:  o pkg/obcs:
36   - bug fix for balance code   - bug fix for balance code
37  o pkg/seaice:  o pkg/seaice:
38    - allow values of SEAICE_elaticParm > 1    - allow values of SEAICE_elasticParm > 1
39    - make lsr boundary conditions free slip (by default)    - add new parameter SEAICE_evpTauRelax as an alternative
40        to SEAICE_elasticParm
41      - make lsr boundary conditions free slip (by default), changes result
42    - add code for no slip boundary conditions for lsr    - add code for no slip boundary conditions for lsr
43    - set minimum of zeta to zero (and not 4e8) (changes results)    - set minimum of zeta to zero (and not 4e8) (changes results)
44      - add a cap on AREA after advecting AREA if seaice_growth is not called
45  o change calculation of Visbeck K:  o change calculation of Visbeck K:
46    - no longer depend on tapering scheme; instead, compute slope (limited    - no longer depend on tapering scheme; instead, compute slope (limited
47      by GM_maxSlope). this is equivalent to what was comuted before with      by GM_maxSlope). this is equivalent to what was comuted before with
48      clipping or linear tappering.      clipping or linear tappering.
49    - fix vertical averaging (wrong by 1 level)    - fix vertical averaging (wrong by 1/2 level)
50    - leave the old version (but will not be maintained) within    - leave the old version (but will not be maintained) within
51      #ifdef OLD_VISBECK_CALC / #endif      #ifdef OLD_VISBECK_CALC / #endif
52      - update output of exp. ideal_2D_oce
53  o change error catch in calc_r_star to improve vectorization  o change error catch in calc_r_star to improve vectorization
54  o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and  o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
55    add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).    add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
56    o adjoint:
57      Re-organized adjoint checkpointing according to Matt Mazloff
58      (but with modifs/completions/cleanups)
59      Storing is now bundled into large arrays to optimized I/O
60      (and second step in cleanup of the_main_loop)

63  o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):  o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
# Line 74  o pkg/exf: some cleaning-up: Line 111  o pkg/exf: some cleaning-up:
111  o pkg/thsice:  o pkg/thsice:
112   fix few little problems, in thsice_calc_thickn.F:   fix few little problems, in thsice_calc_thickn.F:
113    - growth vertically (and not laterally) if iceFrac == iceMaskMax    - growth vertically (and not laterally) if iceFrac == iceMaskMax
114    - melt laterally only if hIce < hThinIce (as the comments say)    - melt only laterally if hIce < hThinIce (as the comments say)
115    and in thsice_extend.F:    and in thsice_extend.F:
116    - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)    - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
117    - start to form ice as soon as the minimum ice-volume is reachable.    - start to form ice as soon as the minimum ice-volume is reachable.
