Linking a program that uses netCDF to a netCDF-4 library allows the program to read compressed data without changing a single line of the program source code. Writing netCDF compressed data only requires a few extra statements. And the nccopy utility program supports converting classic netCDF format data to or from compressed data without any programming.
