etat0_netcdf.F90 @ 3400

Last change on this file since 3400 was 1328, checked in by Laurent Fairhead, 15 years ago

Continent/ocean mask was transformed incorrectly from o2a.nc file
Change of unit for seaice depending on whether the initial data is from
climatology or model results

Erreur sur la transformation vers la grille physique du masque lu dans o2a.nc
