Description
Context
In p4zopt.F90, PAR is computed on the part of the cell that is free of ice. Below sea ice, it is assumed that there is no primary production
Analysis
But when we save it in output "PAR", I think it should be multiplied by the fraction of free-of-ice water to get the PAR mean over the whole cell
Fix
CALL iom_put( "PARDM", zpar(:,:,:) * tmask(:,:,:) * (1-fr_i(:,:)) ) ! Photosynthetically Available Radiation CALL iom_put( "PAR" , emoy(:,:,:) * tmask(:,:,:) * (1-fr_i(:,:)) ) ! Photosynthetically Available Radiation
instead of
CALL iom_put( "PARDM", zpar(:,:,:) * tmask(:,:,:) ) ! Photosynthetically Available Radiation CALL iom_put( "PAR" , emoy(:,:,:) * tmask(:,:,:) ) ! Photosynthetically Available Radiation
