I'm having some peculiar problems reading the Meteosat Multi-sensor
precipitation files in GRIB2.
http://oiswww.eumetsat.int/~idds/html/grib.html (MET-9 files)
I have tried using NCL version 5.0.1 and 5.1.0. NCL_filedump in
version 5.0.1 is able to display most of the variables...

However, lat_0 and lon_0 are not displayed I assume they are entry 98
and 99. I also have tried using NCL_filedump from version 5.1.0 which
results in the following....

Is NCL simply missing the necessary tables? Since I use NCL for most
image processing it would be quite helpful if I didn't have to convert
these files into some other format before reading them into NCL.
Much appreciated!
