Surface Soil Moisture from ENVISAT ASAR GM, 2005-2011, Alaska North Slope and Alaska Highway, Alaska (US)

The SAR Surface Soil Moisture (SSM) product is derived from the ENVISAT ASAR sensor operating in Global Monitoring (GM) mode. The SAR SSM product is a weekly mean composite at 1 km spatial resolution for the years 2005 to 2011. The SAR Surface Soil Moisture parameter represents a relative measure of the soil moisture in the top layer of the soil, scaled between references corresponding approximately to wilting level (0%) and field capacity (100%). In addition to the SSM maps, quality indicator maps provide information on the number of individual SSM retrievals that were averaged in order to achieve the corresponding weekly SSM composites.

More information about the image processing and SSM retrieval can be found in the product guide.
