Problem in Grib data reading as template option

Fri Apr 27 01:12:33 EDT 2007

Dear Rod Teck/Diane

I have several grib file (conataing 6 hourly data for 15 days)  of size
1.5GB each, so I cannot use CAT command to club them in one file. I am using

grib2ctl.pl  -verf griblile > gribfile.ctl

This will make control file of the grib file and then we make index file
for these contol file by command

gribmap -i gribfile.ctl

This procedure we are repeating for all the file now we have .ctl file
and .idx file for each grib file.

My problem is how to use all files in one gs script to calculate the
seasonal or climatological patterns.

with best regards

Pankaj
