You can easily dump the contents of a netCDF file in ASCII using the 'ncdump' utility that is part of our netCDF distribution. You can download the source for the netCDF using anonymous FTP from our FTP server, ftp.unidata.ucar.edu: ftp ftp.unidata.ucar.edu <user> anonymous <pass> address@hidden cd pub/netcdf binary get netcdf.xxx.tar.Z <- actual name will depend on which version you want I recommend starting with netcdf-3.6.1.tar.Z quit tar xvzf netcdf-3.6.1.tar.Z The instructions for building the netCDF from source are contained in the netCDF web pages on our site: http://www.unidata.ucar.edu/software/netcdf This site also has lots of information on what tools are available in the netCDF distribtion and how to download the software. You didn't say what kind of a machine you are using. If it is a Windows machine, you may want to download a prebuilt binary of the netCDF for Windows. The web pages have instructions for doing this. > Specify a new image from the NCEP Reanalysis Surface Flux data set. > So, I would like a site to open my DATA the name of DATA when we save in PC > is FTP a copy of the file :152.92.17.60.126.8.35.1.nc Once you have the netCDF package installed (either built from source or installed from a binary distribution), you would use the utility 'ncdump' to list data from the file. Instructions on using 'ncdump' can be found in the netCDF web pages: netCDF HomePage: http://www.unidata.ucar.edu/software/netcdf Full netCDF Documentation http://www.unidata.ucar.edu/software/netcdf/docs/ The netCDF HomePage also has a list of packages that support the netCDF format: Software for manipulating or displaying netCDF data http://www.unidata.ucar.edu/software/netcdf/software.html I think that our netCDF website will answer most, if not all, questions you hae about netCDF and how to us it. > Thanks again > Elaine Cheers, Tom **************************************************************************** Unidata User Support UCAR Unidata Program (303) 497-8642 P.O.
