Convert the netCDF file to CDL form via the "ncdump" utility, edit the CDL file, and then convert it back to netCDF form. This works for not-too-large dataset. 2. Dump just the header of the netCDF file via the "ncdump" utility, use the "ncgen" utility to create a template program for that data, edit the template program to do what you what, and then execute the program on the netCDF file. This works for any size dataset. (For either of the above, see the netCDF manual pages for further information or <http://www.unidata.ucar.edu/packages/netcdf/docs.html>). 3. Use a 3rd-party package to edit the data. See <http://www.unidata.ucar.edu/packages/netcdf/software.html> for examples. Regards, Steve Emmerson <http://www.unidata.ucar.edu>
