10.2.2 Extrapolation of sea temperatures

SURFEX has a sea fraction, but CANARI has a binary land-sea mask. There is an option to set LEXTRAP_SEA true, to extrapolate the nearest (in space) SST value in point where CANARI has land, but SURFEX has a sea fraction. This is to avoid that the SST gets a too high influence of land temperatures, which can be important in areas with large gradients in land/sea (e.g. fjords).

NAM_ASSIM:

Fortran name Fortran type values default value
LEXTRAP_SEA logical .FALSE.
