Problems with large grib files in GrADS

Post by Antonix » Thu Oct 07, 2010 12:39 am

Hello everyone
to handle large files are moved to a 64-bit version.
but I get strange results.
my siulazione 06oct2010 begins and lasts for 168.
but in the file. ctl start date is 9oct2010 and maps are plotted only by that date!
somebody can help me??

.ctl :

dset ^201010061200_nmm_wrfout_d01.grb
index ^201010061200_nmm_wrfout_d01.idx
undef 9.999E+20

I've you got only one grib file with all forecast hours or one grib file per forecast hour ?

Check a wgrib 201010061200_nmm_wrfout_d01.grb to see what is inside your grib file

The date could be strange too in ctl file :
try to change 09Z09oct2010 to 12Z06oct2010 and gribmap -i the new ctl file

regards JPB
