SMOS

    Project Details

    Description

    SMOS (Soil Moisture and Ocean Salinity) is a continuation of the MIRAS work. SMOS has been selected as one of ESA's Earth Explorer Opportunity Missions and the target launch year is 2005.
    SMOS is a 1.4 GHz system with 73 antenna elements and radiometers on three 4.5 m long arms. In the central unit 2628 correlators are found. The instrument mass is 175 kg and the power consumption is 220 W.
    SMOS will enable global measurement of soil moisture to the 0.04 m3/m3 level with 50 km ground resolution, and, after suitable integration, sea salinity to the 0.1 per mille level with a 200 km ground resolution.
