4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
8    o dependencies: pkg/profiles requires pkg/cal
9    o pkg/profiles:
10     - added option ALLOW_PROFILES_GENERICGRID
11         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
12         that interpolation information (grid points and coefficients) is provided
13         within the netcdf input files.
14         -> sample matlab scripts can be found in MITgcm_contrib/gael
15         that allow you to prepare netcdf input files.
16     - also modified: cleaner include statements, cleaner error print statements,
17       cleaner stops when error, and more tests of the netcdf input files consistency.
18    
19    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
20    o pkg/seaice:
21     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
22       requires a new routine: seaice_diagnostics_fill.F
23     - make sure that seaice does not move if not forced (pressure replacement
24       method, Hibler and Ip, 1995), changes results
25     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
26     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
27       It is turned off by default (=-1.), because it changes the results.
28     - make it possible to read AREA from a file, too.
29    
30    checkpoint59c
31    o add S/R and diagnostics for oceanic mixed-layer depth
32    o move GMRedi call after all vertical mixing schemes (including KPP)
33    o pkg/thsice:
34     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
35      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
36    o pkg/obcs:
37     - bug fix for balance code
38    o pkg/seaice:
39      - allow values of SEAICE_elasticParm > 1
40      - add new parameter SEAICE_evpTauRelax as an alternative
41        to SEAICE_elasticParm
42      - make lsr boundary conditions free slip (by default), changes result
43      - add code for no slip boundary conditions for lsr
44      - set minimum of zeta to zero (and not 4e8) (changes results)
45      - add a cap on AREA after advecting AREA if seaice_growth is not called
46    o change calculation of Visbeck K:
47      - no longer depend on tapering scheme; instead, compute slope (limited
48        by GM_maxSlope). this is equivalent to what was comuted before with
49        clipping or linear tappering.
50      - fix vertical averaging (wrong by 1/2 level)
51      - leave the old version (but will not be maintained) within
52        #ifdef OLD_VISBECK_CALC / #endif
53      - update output of exp. ideal_2D_oce
54    o change error catch in calc_r_star to improve vectorization
55    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
56      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
57    o adjoint:
58      Re-organized adjoint checkpointing according to Matt Mazloff
59      (but with modifs/completions/cleanups)
60      Storing is now bundled into large arrays to optimized I/O
61      (and second step in cleanup of the_main_loop)
62    
63    checkpoint59b
64    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
65      - export/import (between ocean & coupler) fields needed for ocean DIC.
66  o pkg/seaice:  o pkg/seaice:
67    - get rid of three more exchanges seaice_calc_viscosities (required    - get rid of three more exchanges seaice_calc_viscosities (required
68      different loop boundaries in seaice_lsr and seaice_ocean_stress)      different loop boundaries in seaice_lsr and seaice_ocean_stress)
# Line 53  o pkg/exf: some cleaning-up: Line 112  o pkg/exf: some cleaning-up:
112  o pkg/thsice:  o pkg/thsice:
113   fix few little problems, in thsice_calc_thickn.F:   fix few little problems, in thsice_calc_thickn.F:
114    - growth vertically (and not laterally) if iceFrac == iceMaskMax    - growth vertically (and not laterally) if iceFrac == iceMaskMax
115    - melt laterally only if hIce < hThinIce (as the comments say)    - melt only laterally if hIce < hThinIce (as the comments say)
116    and in thsice_extend.F:    and in thsice_extend.F:
117    - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)    - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
118    - 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.
