WebThe attributes scale_factor and add_offset can be used together to provide simple data compression to store low-resolution floating-point data as small integers in a netCDF file. When scaled data are written, the application should first subtract the offset and then divide by the scale factor. When we create a NetCDF file that contains a large database of variables and attributes, space storage and efficiency becomes mandatory. That's why in order to drastically reduce the storage space, it is possible to "pack" the data for a given variable.
