5      ==============================      ==============================
6    
7    o pkg/exf (interpolation):
8      - add a set of run-time param ({inputfield}_interpMethod), one for
9        each interpolated input field, to select the interpolation method
10        with a value of zero switching off the interpolation;
11      - print interpolation parameters to standard output;
12      - refine exf_check.F accordingly ; stop if USE_NO_INTERP_RUNOFF is defined
13        (to use instead runoff_interpMethod=0 in data.exf).
14    o pkg/exf/exf_radiation.F: add the factor ocean_emissivity to lwdown, for
15       within #ifdef EXF_LWDOWN_WITH_EMISSIVITY/#endif. Unless ocean_emissivity=1.
16       this factor is absolutely required, because the lw exitance (= out-going
17       long wave radiation) is emissivity*stefanBoltzmann*T^4 + rho*lwdown,
18       where the reflectivity rho = 1-emissivity for conservation reasons. Once
19       this is established, we can remove the CPP-Flag (if we want to).
20    o pkg/seaice:
21      - qualify a stop statement in S/R seaice_check: EXF_READ_EVAP and
22        ALLOW_BULKFORMULAE are only required if SEAICE_EXTERNAL_FLUXES is defined
23      - sort out emissivity and long wave radiation, step 1: make SEAICE_emissivity
24        what the name implies (and not emissivity*BoltzmannConstant), this means
25        the old default value of 5.5e-8 now means
26        5.5e-8/5.670e-8 = 0.97001763668430343479 as ocean_emissivity in
27        S/R exf_readparms
28      - FV-discretization of the B-grid LSOR solver, turn on with
29        SEAICE_LSRBNEW. This new solver also involves a slight re-organization
30        of the calling routine dynsolver, so that B and C-grid code look a
31        little more alike.
32      - fix index bugs in ostres.F (B-grid code)
33    o pkg/seaice/seaice_ocean_budget.F: change (unused) code to make it look better
34    o pkg/seaice/seaice_readparms.F: make ocean_emissivity*stefanBoltzmann the
35      default for SEAICE_emissivity, if useEXF; requires setting a wrong
36      parameter value in global_ocean.cs32x15/input.seaice/data.seaice for
37      backward compatiblity
38    o model/src: use sigmaR in calc_ivdc
39    
40    checkpoint63g (2011/12/16)
41    o pkg/seaice/seaice_growth.F:
42      fix heat conservation of the coupled ocean-seaice system.
43      when SEAICE_HEAT_CONSERV_FIX is defined, the mismatch of
44      solid vs liquid water treatment is resolved via QNET.
45    o pkg/seaice/seaice_growth.F:
46      add missing term for sublimation in saltFlux, which was breaking conservation.
47    o pkg/seaice/seaice_model.F:
48      Remove this patholigical case treatment in evolution branch,
49      where it is un-necessary and breaks conservation.
50      Update global_ocean.cs32x15/results accordingly for
51      output.seaice.txt output_adm.seaice.txt and output_adm.seaice_dynmix.txt
52  o model/src:  o model/src:
53    useRealFreshWaterFlux: remove masking of EmPmP (using maskInC) in    useRealFreshWaterFlux: remove masking of EmPmP (using maskInC) in
54    external_forcing_surf.F and apply mask directly in S/R SOLVE_FOR_PRESSURE.    external_forcing_surf.F and apply mask directly in S/R SOLVE_FOR_PRESSURE.
