[gradsusr] combining GRIB fiiles

[Sujata Pattanayak]

Hi Teresa,
     Thanks for your kind suggestion.
I tried with your option. Now I am getting
tdef 2 linear ... 3hr
But, when I am trying to plot through grads, for (t=2), entire Grid
Undefined message is coming.
I have uploaded two of my .grb files in the following ftp site.
Please have a look in to it and please suggest me something in this regard.
ftp://ftp.rap.ucar.edu/incoming/irap/sujata

With regards,
Sujata
