We have transitioned the data files from netCDF3 to netCDF4-classic format. As a result, the files are compressed instead of being packed with a scale and offset. As with any netCDF4 file, the user interface will perform the uncompression. We expect the files to be read faster, depending on the application you are using. Please let us know if you run into any issues.
