CLIMCAPS Science Guide
ATBDs: Algorithm Theoretical Basis Documents
ATBDs typically provide the theoretical basis, both the physical theory and the mathematical procedures and possible assumptions being applied, for the calculations that have to be made to convert the radiances received by the instruments to geophysical quantities. The geophysical quantities are then available to the scientific community for studies of the various characteristics of the Earth system.
Algorithm Theoretical Basis Documents (ATBDs) have been developed for EOS instrument products. Some ATBDs address more than one product and some products are addressed by more than one ATBD.
ATBDs for data from the AIRS instrument on Aqua that have been processed with the AIRS retrieval algorithm or processed with the CLIMCAPS retrieval algorithm are served from the NASA Goddard Earth Sciences Data and Information Services Center (GES DISC).
