Hi Kevin,

Your example file has revealed several issues in NetCDF-Java.

1. We should be able to write it out as NetCDF-4, but currently cannot. I've 
created a JIRA issue for this: 
https://bugtracking.unidata.ucar.edu/browse/TDS-609
2. We should be able to write it out as CF/NetCDF-3, but currently cannot. I 
believe I've fixed this: 
https://github.com/cwardgar/thredds/commit/709a0fc7d356fb6506e9d6f01d1cef0ce1b47a7e
3. When the file is run through our Gempak IOSP, there appear to be 216 
stations. However, the dataset I get after converting it to CF/NetCDF-3 only 
contains 191. Additionally, many station IDs are being assigned "9999" 
(missing), but they *should* all be unique. I don't yet know if these issues 
indicate a problem with the example file or our IOSP. I'm going to test it with 
the native Gempak package to find out.

Cheers,
Christian
