[netCDFJava #TOX-206476]: Problems converting GEMPAK point (METAR) data to a usable NetCDF file

Hi Kevin,

netcdf-java can read the example file you sent without any issues. 
Unfortunately, we do not yet have 
a write method that can be used from the command line yet for point data, but 
it is on our todo list
soon - we'll take a look after our THREDDS workshop is finished (the workshop 
is next week).

I'll let you know when we have something ready to go.
