Neither of those packages are Unidata software. They were contributed by other users who apparently moved the software or no longer maintain it. I suggest you use our "ncdump" utility, which we maintain and make available under an open source license. Recent versions of "ncdump", which is a command-line utility, support a "-t" option that displays the time data in human readable form, so instead of trying to figure out what something like time = 7776000, 15552000 ; represents in a unit like time:units = "seconds since 2009-01-01" ; using ncdump -t instead outputs the data and time in ISO-8601 form: time = "2009-04-01", "2009-06-30" ; and includes hours, minutes, and seconds if needed. There's a couple of workshop slides on ncdump here: http://www.unidata.ucar.edu/netcdf/workshops/2012/utilities/Ncdump.html and reference documentation here: http://www.unidata.ucar.edu/netcdf/docs/ncdump-man-1.html You can get ncdump as part of the netCDF software package from a number of package distribution systems, as described here: http://www.unidata.ucar.edu/netcdf/docs/getting.html Its available for Windows in binary form: http://www.unidata.ucar.edu/netcdf/docs_rc/winbin.html and for Mac OSX from MacPorts, which builds it for you from source: http://www.macports.org/ports.php?by=variant&substr=dap If you have a Linux system, building it from the source distribution is very straightforward. --Russ > Thank you so much for your time and help. > I look forward to hearing from you. > > Best Regards, > Sam Ryder > > Intern > Ashoka Trust for Research in Ecology and the Environment (ATREE) > Royal Enclave, Srirampura, Jakkur PO > Bangalore 560064, India > address@hidden > > Russ Rew UCAR Unidata Program address@hidden http://www.unidata.ucar.edu Ticket Details =================== Ticket ID: PJC-763398 Department: Support netCDF Priority: Normal Status: Closed
