R: R: Manage lat-lon thinned grid

[Diego Morelli]

Really??
Did you use grib2ctl (then wgrib), gribmap (contained in the grads 2 packet)
and grads 2?

Here, under grads 2.0.a7, the command perl grib2ctl.pl <file1name>.b >
<file1name>.ctl, issue this error:

missing end section

37 37 30 30
***script needs to be modified
Unknown user-defined grid

Infact the ctl file miss the xdef, ydef information.

After, the command gribmap -I <file1name>.ctl -0, goes in segmentation
fault.

How did you do to manage this kind of file without the need to convert it in
grib2?? It will be very interesting for me...

Diego,

For file #1, I was able to plot it in the original grib1 format. No need
to convert it into grib2.
