Hi Stefan, > is there the posiblity to use "long double" variables for data in netcdf > instead of "double"? No, sorry, "long double" is not a supported primitive type in any of the netCDF format variants. It may be possible to add it to netCDF-4 in the future if there is enough demand, but I can't recall anyone else requesting it before your question. --Russ Russ Rew UCAR Unidata Program address@hidden http://www.unidata.ucar.edu Ticket Details =================== Ticket ID: RAE-945667 Department: Support netCDF Priority: Normal Status: Closed
