Hi Ratna, One tool for extracting data from netCDF files is the ncks program that is part of the NCO (netCDF Operators) software: http://nco.sourceforge.net/ Another software package with this capability is CDO (Climate Data Operators), which has a set orf selection operators, including selname for selecting variables by name: http://www.mpimet.mpg.de/fileadmin/software/cdo/ Also there is a prototype netCDF subset service, which would require a server for the data: http://www.unidata.ucar.edu/projects/THREDDS/tech/interfaceSpec/NetcdfSubsetService.html Other alternatives include use of scripting languages, such as Python, Perl, or Ruby, to select variables using scripts and the appropriate netCDF interfaces. --Russ Russ Rew UCAR Unidata Program address@hidden http://www.unidata.ucar.edu Ticket Details =================== Ticket ID: DPN-329691 Department: Support netCDF Priority: Normal Status: Closed
