Info

Algorithm Theoretical Basis Documents (ATBDs) provide the physical and mathematical descriptions of the algorithms used in the generation of science data products. The ATBDs include a description of variance and uncertainty estimates and considerations of calibration and validation, exception control and diagnostics. Internal and external data flows are also described. The SMAP ATBDs were reviewed by a NASA Headquarters review panel in January 2012 and are currently at Initial Release, version 1. The ATBDs will undergo additional updates after the SMAP Algorithm Review in September 2013.
