Grads 2.0 with grib2 files

[Oliver König]

Hello,
I installed Grads 2.0 binaries on Debian/GNU Linux testing (64 bit) because I
want to work with grib2  data from NCEP.

Installation of grads 2.0 binaries
----------------------------------
$ wget ftp://iges.org/grads/2.0/grads-bin-2.0.a0-RHEL5-x86_64.tar.gz
$ tar xvfz grads-bin-2.0.a0-RHEL5-x86_64.tar.gz
$ cp grads-2.0.a0/bin/* /usr/bin

Installation of grads data files
--------------------------------
$ cd /usr/local/lib/
$ mkdir grads
$ cd grads
$ wget ftp://iges.org/grads/data.tar.Z
$ tar xvfz data.tar.Z

Test grib2 data in grads
---------------------------
$ wget ftp://ncep.domain.tld/gfs_grib2.file
$ g2ctl.pl -verf gfs_grib2.file > gfs_grib2.ctl
$ gribmap -i gfs_grib2.ctl

$ grads
ga-> open gfs2_grib2.ctl
ga-> q file
ga-> d tmpsfc
Cannot contour grid - all undefined values

The grib2.file is from an operational NOAA/NCEP server so I guess the file and
the format are okay. I managed to display grib1 data in Grads 2.0. does
anyone have an idea what the problem is? Help is welcome. thanks!

Regards,
