Dear Harry and others,
One of our developers created a work-around for this problem, and it
will be available in the next version of NCL (no scheduled date
yet).
Here's some info on the work-around, In the developer's own words:
This is a workaround fix for Grib files from the IPCC Data
Distribution Center. (http://cera-www.dkrz.de/IPCC_DDC/)
Several unrecognized centers are used for these files. The
work-around code is activated when an unrecognized center is
encountered. I have only looked at a limited number of these
files, so I do not know how comprehensive this fix is.
User-defined parameter tables are still needed and I do not
attempt to supply a name for the center.
If anybody wants to try this new version of NCL now, send me a
personal email (haley AT ucar.edu) and I'll see if I can provide you with
a precompiled binary.
--Mary
