7    o pkg/exf/exf_radiation.F: add the factor ocean_emissivity to lwdown, for
8       within #ifdef EXF_LWDOWN_WITH_EMISSIVITY/#endif. Unless ocean_emissivity=1.
9       this factor is absolutely required, because the lw exitance (= out-going
10       long wave radiation) is emissivity*stefanBoltzmann*T^4 + rho*lwdown,
11       where the reflectivity rho = 1-emissivity for conservation reasons. Once
12       this is established, we can remove the CPP-Flag (if we want to).
13    o pkg/seaice:
14      - qualify a stop statement in S/R seaice_check: EXF_READ_EVAP and
15        ALLOW_BULKFORMULAE are only required if SEAICE_EXTERNAL_FLUXES is defined
16      - sort out emissivity and long wave radiation, step 1: make SEAICE_emissivity
17        what the name implies (and not emissivity*BoltzmannConstant), this means
18        the old default value of 5.5e-8 now means
19        5.5e-8/5.670e-8 = 0.97001763668430343479 as ocean_emissivity in
20        S/R exf_readparms
21      - FV-discretization of the B-grid LSOR solver, turn on with
22        SEAICE_LSRBNEW. This new solver also involves a slight re-organization
23        of the calling routine dynsolver, so that B and C-grid code look a
24        little more alike.
25      - fix index bugs in ostres.F (B-grid code)
26    o pkg/seaice/seaice_ocean_budget.F: change (unused) code to make it look better
27  o pkg/seaice/seaice_readparms.F: make ocean_emissivity*stefanBoltzmann the  o pkg/seaice/seaice_readparms.F: make ocean_emissivity*stefanBoltzmann the
28    default for SEAICE_emissivity, if useEXF; requires setting a wrong    default for SEAICE_emissivity, if useEXF; requires setting a wrong
