Yes, you can get the prebuilt library and command-line utilities from here: http://www.unidata.ucar.edu/downloads/netcdf/ftp/netCDF4.3.3.1-NC4-DAP-32.exe and instructions for installing from here: http://www.unidata.ucar.edu/netcdf/docs/winbin.html --Russ > -----Original Message----- > From: Unidata netCDF Support [mailto:address@hidden] > Sent: Friday, May 22, 2015 11:43 AM > To: address@hidden > Cc: address@hidden > Subject: [netCDF #NBS-703757]: A Reader for This File > > Hi Jim, > > > I was referred to you by the ESRL to get a reader for this file.
