Greetings Brian, I just saw your reply - sorry about that! When you tried to load the ncml file, was the file in the same directory as the original prmsl_1878.nc file? You will see this kind of error when the original file referenced in the NcML file does not exist. If you are using a different file, you will need to make sure to update the location attribute in this line: <netcdf xmlns="http://www.unidata.ucar.edu/..." location="./CAM5_onetime.nc"> with the *full* path to the original file. I used "./<filename>", which assumes the netCDF file is in the same directory as the NcML file.
