    SMOS Level 2 Soil Moisture
    (2369) recent views
    Last update: 8 May 2015

    The Level 2 SM product comprises soil moisture measurements geo-located in an equal-area grid system ISEA 4H9.

    The product contains not only the retrieved soil moisture, but also a series of ancillary data derived from the processing (nadir optical thickness, surface temperature, roughness parameter, dielectric constant and brightness temperature retrieved at top of atmosphere and on the surface) with the corresponding uncertainties.

    The pixels are consolidated in a pole-to-pole product file (50 minutes of sensing time), with a maximum size of about 7MB (25MB uncompressed data) per half orbit (29 half orbits per day). Spatial resolution is in the range of 30-50 km.
