4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o add S/R and diagnostics for oceanic mixed-layer depth
8    o move GMRedi call after all vertical mixing schemes (including KPP)
9    o pkg/thsice:
10     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
11      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
12    o pkg/obcs:
13     - bug fix for balance code
14    o pkg/seaice:
15      - allow values of SEAICE_elasticParm > 1
16      - add new parameter SEAICE_evpTauRelax as an alternative
17        to SEAICE_elasticParm
18      - make lsr boundary conditions free slip (by default), changes result
19      - add code for no slip boundary conditions for lsr
20      - set minimum of zeta to zero (and not 4e8) (changes results)
21      - add a cap on AREA after advecting AREA if seaice_growth is not called
22    o change calculation of Visbeck K:
23      - no longer depend on tapering scheme; instead, compute slope (limited
24        by GM_maxSlope). this is equivalent to what was comuted before with
25        clipping or linear tappering.
26      - fix vertical averaging (wrong by 1/2 level)
27      - leave the old version (but will not be maintained) within
28        #ifdef OLD_VISBECK_CALC / #endif
29      - update output of exp. ideal_2D_oce
30    o change error catch in calc_r_star to improve vectorization
31    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
32      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
33    o adjoint:
34      Re-organized adjoint checkpointing according to Matt Mazloff
35      (but with modifs/completions/cleanups)
36      Storing is now bundled into large arrays to optimized I/O
37      (and second step in cleanup of the_main_loop)
38    
39    checkpoint59b
40    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
41      - export/import (between ocean & coupler) fields needed for ocean DIC.
42    o pkg/seaice:
43      - get rid of three more exchanges seaice_calc_viscosities (required
44        different loop boundaries in seaice_lsr and seaice_ocean_stress)
45      - bug fix in seaice_ocean_stress (update of lab_sea required)
46      - reduce loop boundaries to necessary minimum also in seaice_evp
47      - go back to the old way of computing deltaC/Z as the adjoint likes that
48        better
49    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
50      passive tracer to an Age Tracer) + update output.txt
51    o pkg/exf:
52      - implement A-grid / C-grid selection for wind-stress input files.
53      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
54      for now, in exf_bulk_largeyeager04.F only :
55      - change implementation for case where windspeed + 2. components wind-stress
56        are read-in. AND use rhoConstFresh to convert evap.
57    o pkg/seaice:
58      - use correct EXCH_UV for wind-forcing (on A-grid).
59      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
60        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
61    o pkg/exf:
62      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
63      EXF_INTERPOLATION:
64      - merge global_with_exf/code version of exf_interp_read.F
65        to the main code ;
66      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
67        reading the file ; Important: This options needs to be defined to recover
68        previous code.
69        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
70      - no longer loose real*8 precision along the way when using exf_iprec=64.
71  o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)  o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
72    - change discretisation of evp-solver in order to avoid another exchange    - change discretisation of evp-solver in order to avoid another exchange
73      (changes lab_sea) and clean up a little      (changes lab_sea) and clean up a little
# Line 24  o pkg/exf: some cleaning-up: Line 88  o pkg/exf: some cleaning-up:
88  o pkg/thsice:  o pkg/thsice:
89   fix few little problems, in thsice_calc_thickn.F:   fix few little problems, in thsice_calc_thickn.F:
90    - growth vertically (and not laterally) if iceFrac == iceMaskMax    - growth vertically (and not laterally) if iceFrac == iceMaskMax
91    - melt laterally only if hIce < hThinIce (as the comments say)    - melt only laterally if hIce < hThinIce (as the comments say)
92    and in thsice_extend.F:    and in thsice_extend.F:
93    - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)    - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
94    - 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.
