Betreff: Grib2-Decoder

Dear Mr. Kambic,

my name is Katja Moritz and i am working for the Bavarian Environment Agency in 
Munich, Germany at the Flood Information Centre.
Since the German Wether Service (DWD) will provide us in the future with 
grib2-data it is my task to process this data.
We already use some Java-Applications so it would be great, if we could use 
your Java-Decoder!
I already made a first attempt to read a testfile from the DWD (see 
attachement) and it worked out fine. Only the values i receive with the 
getData()-Method of the Grib2DataSection can't be correct - they are fare too 
negative. I already compared the values with the values i get with the 
C-program GRIB API (ECMWF). Those values looked ok.
What do you think is wrong with the data? Do i use your code correctly?

Many thanks in advance und many greetings from Munich!

Yours sincerely,
Katja Moritz
