[gradsusr] gribmap with GRIB2

[Gebhardt Christoph]

Hi Wesley,

thank you for the links.
It works in a sense that I actually get the data plotted. The GRIB2 PDTS 4.6 and 4.10 are decoded.

Do get the plots, I used alt_g2clt with option –raw (my GRIB2 fields are in rotated lon-lat). Without –raw, the ctl-file didn't work.
After replacing the start coordinate and the grid spacing in XDEF and YDEF from 0 0.1 to the correct values,
I used alt_gmp and it worked.
However, the two records in the GRIB2 file which are different in the percentile value are not properly identified.
The ctl-File assumes that there is just one record and accordingly, I was able to plot only one record.

In general, by splitting my GRIB2 field to individual records, I could work with alt_g2ctl and alt_gmp.

Christoph.
