Re: Netcdf-Java guidance needed

Hi David:

  http://www.unidata.ucar.edu/software/netcdf/examples/programs/

has some complete programs that should be helpful.

we dont yet have the MADIS data being served through a THREDDS Data Server. We 
are working on that and will keep you informed. You might look at our 
experimental METAR server at

  http://motherlode.ucar.edu:8080/thredds/ncss/metars/dataset.html

this service will be up and down, but any feedback would be appreciated.

good luck!
