surf_seaice_mod.F90 @ 2237

Last change on this file since 2237 was 2227, checked in by Laurent Fairhead, 10 years ago

New ocean albedo.

To activate the new scheme, put iflag_albedo=1 in physiq.def

To activate chlorophyll concentration effect on albedo,
put ok_chlorophyll=y in def file

and download file named chlorophyll.nc
chlorophyll.nc has the same dimension as the model grid with 12 months data,
(i=lon, j=lat, L=1:12) and can be degraded from the original file of dimension
i=1:4320 , j=1:2160 , L=1:12
ada:/workgpfs/rech/psl/rpsl949/clima/chlor_seasonal_clim_seawifs.nc

For 96X96 resolution, chlorophyll.nc file is in
ada:/workgpfs/rech/psl/rpsl949/clima/chlorophyll.nc
