[netCDF #QEB-649105]: transformations

Hello,

The NetCDF data format doesn't have any in-place/internal data transformation 
functionality similar to what you are looking for, unfortunately. You would 
need software to read the data from a NetCDF file and apply the transformation. 

Sorry I can't provide a more immediately helpful answer, have a great day,

Ward
