[netCDFJava #TYF-271558]: Nexrad level 3 reading error

Hi Jonathan,

I took the file you sent and stepped through our radar file reader.  The error 
you are seeing comes up when the code thinks it finds a product with product 
code -252.  I checked the NCDC level 3 radar products 
(http://www.ncdc.noaa.gov/oa/radar/productsdetail.html), and I could not find 
the code listed (nor any code with a negative number).  I'd have to dig deeper 
to see if this is a bug in how we open the file, so can you tell me for certain 
that this file isn't corrupt somehow?  Can you open it using a tool that 
doesn't rely on netcdf-java?
