AMSR-E and AMSR2 TB-based SMAP time-expanded daily 0.25°×0.25° land surface soil moisture dataset in Qilian Mountain Area (SMsmapTE, V1)

AMSR-E and AMSR2 TB-based SMAP time-expanded daily 0.25°×0.25° land surface soil moisture dataset in Qilian Mountain Area (SMsmapTE, V1)


This dataset contains SMAP time-expanded daily 0.25°×0.25° land surface soil moisture products in Qilian Mountain Area from June 19, 2002 to Dec 31, 2021. The dataset was produced based on Random Forest method by utilizing AMSR-E and AMSR2 brightness temperature from 6.925 GHz V/H, 10.65 GHz V/H and 36.5 GHz V channels along with some auxiliary datasets. The auxiliary datasets participating in the RF training include IGBP land cover type, GTOPO30 DEM and Lat/Lon information.
