Level 0: Raw data in propriety format; suitable for re-processing.

Level 1: Data measured with calibration but no interpretation or assumptions. Basic product provided by the manufacturer.

Level 2: Data processed with some degree of smoothing, or averaging, or interpretive algorithms.

Level 3: Data package for easy access and presentation.

Every data file has an associated metadata file. (NETCDF Structure)

 

Every data point at levels 2 and 3 has a Quality Control index.
