Abstract

SMOS (soil moisture and ocean salinity) is the second Earth Explorer Mission of Opportunity within the European Space Agency (ESA) Living Planet Program. The purpose of the SMOS mission is to provide soil moisture and ocean salinity maps from space. The mission is comprised of a satellite that measures the electromagnetic noise generated by Earth at L- band (1.4 GHz) with a spatial resolution of 50-100 Km and radiometric sensitivity of 5 K. SMOS detects the electromagnetic radiation at L band where microwave theorists have encountered a direct relationship between soil moisture and ocean salinity with Earth emissivity. SMOS single instrument is a innovative 2D synthetic aperture interferometric radiometer.
