Hi Julia, I don't know of a COARDS compliance test program, but you can run "ncdump -c" on a file and compare the output with the COARDS conventions: http://ferret.wrc.noaa.gov/noaa_coop/coop_cdf_profile.html The CF conventions were designed to be a compatible extension of the COARDS conventions, so sometimes CF-compliant files are also COARDS-compliant. Sorry, but we don't have any examples for using GMT with netCDF files. --Russ Russ Rew UCAR Unidata Program address@hidden http://www.unidata.ucar.edu Ticket Details =================== Ticket ID: BGF-473127 Department: Support netCDF Priority: Normal Status: Closed
