Hi Mike, the file I tried was download from the NECP website ( http://www.esrl.noaa.gov/psd/data/gridded/data.ncep.reanalys is.html) resently, and it said that "We have transitioned the data files from netCDF3 to netCDF4-classic format on Monday Oct 20th, 2014." on this webpage. So I am sure the file is not a classic netCDF3 file.

I also tried the old way and got the error "NC_ERROR=-51"

IDL> filename='E:\netcdf4.nc'
IDL> cdfid=ncdf_open(filename)
% Loaded DLM: NCDF.
% NCDF_OPEN: Unable to open the file "E:\netcdf4.nc". (NC_ERROR=-51)
% Execution halted at: $MAIN$

Really appreciate your kindly help and patience.
