SST file For ETA MODEL is missing on the net . (help)

[Eric Altshuler]

Dear Sibachir Nordine,

This file is no longer available in GRIB1 format. NCEP only provides GRIB2 data on its ftp server. The GRIB2 version of the SST file is at:

ftp://ftpprd.ncep.noaa.gov/pub/data/nccf/com/gfs/prod/sst.YYYYMMDD/sst2dvar_grb_0.5.grib2

You need to install cnvgrib which can be found at:

http://www.nco.ncep.noaa.gov/pmb/codes/GRIB2/

After installing cnvgrib, convert the GRIB2 SST file to GRIB1 format:

cnvgrib -g21 sst2dvar_grb_0.5.grib2 sst2dvar_grb_0.5

Now you can use the output GRIB1 file (sst2dvar_grb_0.5) in the ETA model.
