The main purpose of this document is to provide a detailed definition of the processes and algorithms contained in the Foreign Sources Correction and Image Reconstruction modules for SMOS Level-1B products.
SMOS will be the first satellite mission to provide global measurements of two key variables in the water cycle, soil moisture and ocean salinity. But how do we get from the first observations to meaningful data on the various characteristics of Earth's surface?
This article was published in the ESA Bulletin Nr. 111 and describes the applications of the ESA's second Earth Explorer Opportunity Mission, the Soil Moisture and Ocean Salinity (SMOS) mission, scheduled for launch in early 2007.
