CHAPITRE 2. THE PHYSIOGRAPHIC FIELDS
SEAFLUX scheme
Treat SST as a forcing variable. For that purpose, several SST files at a given time are required
and namelist NAM DATA SEAFLUX should be filled.

– LSST DATA : flag to initialize SST from a climatology
– NTIME : number of SST input files
– CFNAM SST : SST data file name
– CFTYP SST : type of SST data file (’DIRECT’, ’BINLLF’, ’BINLLV’, ’ASCLLV’)
– NYEAR SST : year of SST data file
– NMONTH SST : month of SST data file
– NDAY SST : day of SST data file
– XTIME SST : time in seconds of SST data file
How to initialise SST from external files : an example with 3 SST input files (lat, lon, value
type).

– XUNIF xxx : uniform prescribed value of parameter xxx. If XUNIF xxx is set, file CFNAM xxx is not used.
– CFNAM xxx : data file name associated to parameter xxx. If XUNIF xxx is set, file CFNAM xxx is not used.
– CFTYP xxx : type of sea data file (’DIRECT’, ’BINLLF’, ’BINLLV’, ’ASCLLV’)
