Howdy Sam! I hope all you BADC folk are enjoying some nice Spring weather. The netCDF binary standard is documented here: http://www.unidata.ucar.edu/software/netcdf/docs/netcdf/File-Format-Specification.html The latest netCDF docs can always be found here: http://www.unidata.ucar.edu/software/netcdf/docs/ The docs are also shipped with each netCDF distribution. The file format is described in the NetCDF Users' Guide. Hope this answers your question!
