Karthik,
The first step is to create a cdl file for the data with the gribtocdl
command. Take a file that has all the parameters in the data set , ie
% gribtocdl -v < rawdata > grib.cdl
This is the cdl file for the data, it usually needs to be modified
somewhat because the GRIB data is complex. One can look at the raw data
with the gribdump command, ie
% gribdump -h rawdata | more
Then run the gribtonc command, ie
% gribtonc -vl - grib.cdl grib.nc < rawdata
There are man pages for detail info on all the commands.
