The CDC maintains information on how to read their NetCDF reanalysis files at:
http://www.cdc.noaa.gov/PublicData/read-our-files.html

They list several software packages for reading and plotting the files,
including Grads, Feret, and IDL. There is also a fortran77 source 
for the starting point to read the files.

Unidata maintains the NetCDF libraries which you can use with your
fortran77 programs for reading the data. Our NetCDF library distribution
can be found on our anonymous ftp server at ftp.unidata.ucar.edu, under
pub/netcdf.
