10.2.1 Sea properties from data source

At the moment no particular data assimilation is done for the sea-tile and only SST is modified. Depending on the namelist options in NAM_ASSIM the sea properties the SST is taken from the following sources:

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

If LAESST is true the SST in SURFEX is overwritten by the SST entering assim_sea_n as input. If LREAD_SST_FROM_FILE is true, this value is read from file. The typical HIRLAM usage is to read this from the boundary file, which is from ECMWF based on the UK OSTIA product.

if LAESST is false, the SST is set from the SST possibly analysed by CANARI.
