This Algorithm Theoretical Basis Document (ATBD) describes our current working model of the algorithm for estimating bulk sea surface temperatures from the MODIS mid-and far-infrared bands. While effort has been made to make this document as complete as possible, it should be recognized that algorithm development is an evolving process. This document (V2. 0) is a description of the prototype algorithm for MODIS sea surface temperature estimation as it currently exists, and has been delivered to NASA for inclusion in the MODIS processing scheme.

Current research on the physics of the atmospheric transmission in the infrared, of the processes at the ocean surface, and new information about the performance of the MODIS will lead to periodic revisions of the algorithms. Also, the document may appear incomplete in places as research continues to improve our understanding of the processes at work. Subsequent revisions of the document will reflect new knowledge and, it is hoped, fill the gaps in what is reported here.
