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 packaged 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.
Data already in the archive
Potential or planned data products – will be updated when these are available
