snow and ice melt rate

rdmsnif/rdt_ice is snow melt rate (m/s) averaged over ice covered area, and not over the entire grid cell. Otherwise the code below should include the coefficient "1-frld" in the last term:

limsbc_2.F90

!  computing freshwater exchanges at the ice/ocean interface

            zemp = + emp(ji,jj)     *         frld(ji,jj)      &   !  e-p budget over open ocean fraction 

               &   - tprecip(ji,jj) * ( 1. -  frld(ji,jj) )    &   !  liquid precipitation reaches directly the ocean

               &   + sprecip(ji,jj) * ( 1. - pfrld(ji,jj) )    &   !  change in ice cover within the time step

               &   + rdmsnif(ji,jj) * r1_rdtice                    !  freshwater flux due to snow melting
