Howdy Tony!

There are several such programs, including ncdump, the canonical dumper of 
netCDF files, which comes with the library and is written here at the Unidata 
Program Center by Russ Rew.

Full documentation can be found here: 
http://www.unidata.ucar.edu/software/netcdf/docs/netcdf/ncdump.html

Basically, ncdump -h to get just metadata, or without the -h to get the data 
dumped as well (inadvisable with large files).

There is another utility called ncgen, which takes the output of ncdump and 
generates the binary file.

Are you producing NPOESS data or using it?

Thanks,

Ed
