5      ==============================      ==============================
6    
7    checkpoint59b
8    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
9      - export/import (between ocean & coupler) fields needed for ocean DIC.
10    o pkg/seaice:
11      - get rid of three more exchanges seaice_calc_viscosities (required
12        different loop boundaries in seaice_lsr and seaice_ocean_stress)
13      - bug fix in seaice_ocean_stress (update of lab_sea required)
14      - reduce loop boundaries to necessary minimum also in seaice_evp
15      - go back to the old way of computing deltaC/Z as the adjoint likes that
16        better
17    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
18      passive tracer to an Age Tracer) + update output.txt
19    o pkg/exf:
20      - implement A-grid / C-grid selection for wind-stress input files.
21      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
22      for now, in exf_bulk_largeyeager04.F only :
23      - change implementation for case where windspeed + 2. components wind-stress
24        are read-in. AND use rhoConstFresh to convert evap.
25    o pkg/seaice:
26      - use correct EXCH_UV for wind-forcing (on A-grid).
27      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
28        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
29    o pkg/exf:
30      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
31      EXF_INTERPOLATION:
32      - merge global_with_exf/code version of exf_interp_read.F
33        to the main code ;
34      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
35        reading the file ; Important: This options needs to be defined to recover
36        previous code.
37        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
38      - no longer loose real*8 precision along the way when using exf_iprec=64.
39    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
40      - change discretisation of evp-solver in order to avoid another exchange
41        (changes lab_sea) and clean up a little
42      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
43        help the adjoint (this also changes the results slightly)
44      - add a few "_d 0" where they had been missing in seaice_evp.F
45      - cleaning up: remove unused seaice_calc_rhs.F
46    o pkg/exf: some cleaning-up:
47      - change various "constants" into runtime parameters
48      - cleaned-up Large&Yeager04 routine which should eventually
49        replace exf_bulkformulae.F (changed names of S/R and CPP)
50        and merged various ALLOW_ATM_WIND options
51     only used with thsice pkg (in thsice_get_exf.F):
52      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
53        which are used when useStabilityFct_overIce=TRUE (= the default)
54      - change default values of ice & snow emissivity and scale downward LW
55        by ice & snow emissivity.
56    o pkg/thsice:
57     fix few little problems, in thsice_calc_thickn.F:
58      - growth vertically (and not laterally) if iceFrac == iceMaskMax
59      - melt laterally only if hIce < hThinIce (as the comments say)
60      and in thsice_extend.F:
61      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
62      - start to form ice as soon as the minimum ice-volume is reachable.
63     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
64      and cpl_aim+ocn
65    o pkg/kpp
66     - move computation of surface related input fields to KPP into a new
67       subroutine kpp_forcing_surf.F
68     - remove wrong (within bi,bj loops) EXCH calls.
69     - little cleaning (add argument myThid in last position, cvs header ...)
70     - for now, fix conservation problem by exchanging KPPviscAz (may not
71       be the best fix)
72    o pkg/seaice
73     - check for inconsistent evp parameter/cpp-flag combination
74     - remove leftover errIO flat for obsolete name list error handling
75    o OpenAD
76     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
77    
78    checkpoint59a
79    o pkg/seaice: some parameter clarifications and a little bit of clean up
80    o pkg/thsice: rename run-time parameters:
81       himin       -> hIceMin
82       himin0      -> hThinIce
83       hihig       -> hThickIce
84       i0          -> i0swFrac
85       transCoef   -> bMeltCoef
86       frac_energy -> fracMelting
87      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
88       with default values (for now) that do not change the results.
89      remove old version of thsice vars advection in pkg/seaice.
90    o in FFIELDS.h:
91      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
92      - make pLoad & sIceLoad always available (but still only used if
93         ATMOSPHERIC_LOADING is #define).
94    o pkg/kpp: replaced _KPP_RL with _RL
95    o bug fixes for vertical diffusivity computations when both KPP and
96        3D diffusivity arrays are used.
97    o pkg/seaice: fix bug in evp solver, while doing that
98      - change (improve?) discretization of stress computations for both
99        cgrid-lsr and evp solver
100      - add a new routine to compute strain rates
101      - the above changes lab_sea results
102      - add no slip conditions for evp solver (off by default), lsr-version
103        may follow
104      - fix exchange for shear at Z-points (does not change lab_sea)
105      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
106        (to force the user to pick a time step since there is not "safe" way
107        of choosing it)
108      - add principal stress diagnostics
109      - rearrange fields for evp a little to avoid having to call a: too many
110        exchanges and b: exchanges for stress trensor components which we do
111        not have.
112      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
113        of evp, complete rewrite for lsr case (latter is does not yet work
114        in all cases)
115    o pkg/kpp: add code to have mixing in shelf ice caverns
116      - add myThid to all kpp routines (long overdue)

126      - retire many _CLIM routines, and remove data.exf_clim
127        + params moved to data.exf
128        + climsst, climsss now handled by exf_set_gen, i.e.
129          climss?period=0 refers to constant field,
130          climss?period=-12 to monthly forcing
131      - split up namelists in data.exf
