Hi John,
The NetCDF Java library seems to be having problems with certain partially zlib compressed Level-III files. Here is part of the stack trace: 

ERROR on inflation unknown compression method
java.util.zip.DataFormatException: unknown compression method
       at java.util.zip.Inflater.inflateBytes(Native Method)

I attaching the two files, one bad, one good.
N0R_20050721_2042 (BAD)
N0R_20050721_2047 (GOOD)
Thanks for your help on this. The NetCDF library and decoders are extremely useful! Thanks!
