SSM-ASCAT-NRT-DIS (H08)
Disaggregated Metop ASCAT NRT SSM at 1 km NRT
pre-operational
Maps of the soil moisture content in the surface layer (0-2 cm) generated from the Advanced Scatterometer (ASCAT) limited to the H SAF area, processed shortly after each satellite orbit completion. It is generated by disaggregating the Metop-B ASCAT NRT soil moisture 25 km sampling product, to 0.5-km sampling with downscaling parameters derived from ENVISAT ASAR (C-band).

SM-DAS-2 (H14)
Soil Wetness Profile Index in the roots region retrieved by Metop ASCAT surface wetness scatterometer assimilation method
operational
Liquid soil moisture profile index for four different soil layers generated by the ECMWF soil moisture assimilation system at 24h time steps. Soil moisture fields are based on a modelled first guess, the screen-level temperature and humidity analyses, and the ASCAT-derived surface soil moisture.
