Hello,
I downloaded the gribfile gfs.t00z.sfluxgrbf2. I want to
use the file to display meteorological data in grads. Here is what I did:
oliver at blizzard:~$ export PATH=$PATH:/opt/grads/bin
oliver at blizzard:~$ export GADDIR=/opt/grads/data
oliver at blizzard:~$ /opt/grads/bin/grib2ctl.pl gfs.t00z.sfluxgrbf21 > gfs.ctl
Undefined parameter table (center 7-0 table 129), using NCEP-opn
oliver at blizzard:~$ gribmap -i gfs.ctl
gribmap: Scanning binary GRIB file(s):
gribmap: Opening GRIB file gfs.t00z.sfluxgrbf21
gribmap: Reached EOF
gribmap: Writing the map...
oliver at blizzard:~$ gradshdf
Landscape mode? (no for portrait): y
GX Package Initialization: Size = 11 8.5
ga-> open gfs.ctl
Scanning description file: gfs.ctl
Data file gfs.t00z.sfluxgrbf12 is open as file 1
LON set to 0 360
LAT set to -89.761 89.761
LEV set to 25800 25800
Time values set: 2005:7:23:0 2005:7:23:0
ga-> d UGRD10m
Cannot contour grid - all undefined values
Is this due to an error when creating the gfs.ctl file? How can I fix the
problem?
Best regards,
