g2ctl

g2ctl takes GRIB2 files and makes GrADS control files. For Grib-1 files, see grib2ctl.

g2ctl make GrADS control files for grib2 files. Requirements include GrADS v2.0+, wgrib2 and perl are needed. Whenever you update g2ctl, you must update wgrib2.

For analyses: (not supported by GrADS yet)

$ g2ctl -O grib2_file >grib_file.ctl
$ gribmap -O -i grib2_file.ctl
$ grads
Landscape mode? (no for portrait):
ga-> open grib_file.ctl

For forecasts:

$ g2ctl grib2_file >grib_file.ctl
$ gribmap -i grib2_file.ctl
$ grads
Landscape mode? (no for portrait):
ga-> open grib_file.ctl

Requirements:
The current version of wgrib2
GrADS v2.0+

Gaussian thinned grids (GrADS problem, I think)

GrADS 2.0 supports an "ensemble" dimension. If you want a try at adding this feature, you're welcome to try.
