Hi Mez, NCO files could refer to data files processed by programs from the NetCDF Operators (NCO) package developed and maintained by Charlie Zender: http://nco.sourceforge.net/ Although NCO programs can output text, they are primarily intended to take netCCDF files as input and produce netCDF files as output. NetCDF files typically use a ".nc" extension in the file name, but that's just a convention. Some older netCDF files might also use a ".cdf" filename extension. If the filenames confirm these are netCDF files, you can use the "ncdump" utility program to see the structure of the data. The ncdump program is part of the freely available netCDF package: ftp://ftp.unidata.ucar.edu/pub/netcdf/netcdf.tar.gz which is documented here: http://www.unidata.ucar.edu/software/netcdf/ --Russ --Russ Russ Rew UCAR Unidata Program address@hidden http://www.unidata.ucar.edu Ticket Details =================== Ticket ID: VRB-949421 Department: Support netCDF Priority: Normal Status: Closed
