The Sentinel-5 Precursor Algorithm Theoretical Baseline Documents (ATBDs) for the operational Level 1b and Level 2 processors are now available in the Document Library.

The documents describe the algorithms that will be used to retrieve the Level 1b and Level 2 products from Sentinel-5 Precursor measurements, the input and ancillary data that is needed, and the output that will be generated. In addition, information about expected calculation times and the expected accuracy are provided.
