Addendum: it looks like the function nc_get_var_short is defined in the file module_netcdf_nc_interfaces.f90_ You should be able to use that if you are willing to convert the resulting signed shorts to unsigned. Alternatively, you might be able to use nc_get_var_int which if applied to a ushort variable should give the proper result as a 4-byte integer. =Dennis Heimbigner Unidata Ticket Details =================== Ticket ID: YYH-497732 Department: Support netCDF Priority: Normal Status: Closed
