We will concentrate on describing the Level-2 algorithms which cover land, water and atmospheric products. The land products comprise atmospherically corrected surface reflectances, vegetation health status, material identification and land temperature and emissivities. The water related products are: water mask, water quality and water temperature. The atmospheric products are: cloud mask, cirrus mask and atmospheric water vapor. We will present several of these algorithms and present results from simulated MTI data derived from AVIRIS and MAS. Biographical sketch: Christoph C. Borel received the Diploma in Electrical Engineering from the Swiss Federal Institute of Technology (1981), and a Ph.D. from the University of Massachusetts (1988). He joined the Los Alamos National Laboratory in 1988 as a post doctoral fellow and is currently a staff member working on various remote sensing projects. His current interests are in atmospheric correction of satellite imagery, scene simulation in the visible and infrared, and end-to-end modeling of hyperspectral sensors and TOA albedo of the Earth. Key words: multispectral analysis, thermal infrared, cloud mask, water mask, atmospheric correction
