Dear GRADS users,
I would like to plot GFS data, for example
gfs.t00z.pgrbf00 for 00Z 01/03/2008, the ctl file is
gfs.t00z.pgrbf00.ctl, the idx file is
gfs.t00z.pgrbf00.idx by WINDOWS's GRADS Version
1.8SL11 (all of them are in the same directory of
GRADS).
However, when I run the script the following thing
happened :
Open Error : Memory allocation error in gaddes.c
The data file was not opened
(This happened only with GFS and NOGAPS files those I
downloaded from Internet).
So please help me by guiding me how to overcome this.
Thank you very much.
Best regards,
Phuong
The ctl file is as following :
******
dset ^gfs.t00z.pgrbf00
index ^gfs.t00z.pgrbf00.idx
undef 9.999E+20
title gfs.t00z.pgrbf00
