Greetings Jeff,

If you are dealing with GRIB files, you should use netCDF-Java 4.3. The
GRIB handling in 4.2 is broken. See the note for GRIB users here and try 
the 4.3 jar:

> 
> I downloaded and installed netcdf-4.2.jar on my Windows laptop. My need is
> to read GRIB2 files from NCEP. I have encountered several problems. The
> most serious is that, according to the documnentation, objects from
> the class Grib2ProductDefintionSection have a method that returns an
> object of the class Grib2PDSVariables, but there is no such class as
> Grib2PDSVariables in the package.
> 
> Another serious problem is that the class Grib2GridDefinitionSection
> does not appear to read in the correct number of bytes. This results in
> an array out of bounds exception being raised in line 1741 of method
> getInt in Grib2GDSVariables.java (which is called from line 82 of
> GribGDSVariables.java, which in turn is in a method called from line
> 418 of Grib2GridDefinitionSection.java). I have verified that all the
> GRIB2 files that I have tested with are properly constructed GRIB2 files.
