AMSR-E/Aqua root zone soil moisture (LPRM) L3 1 day 25 km x 25 km descending and 2-Layer Palmer Water Balance Model V001 (LPRM_AMSRE_D_RZSM3) at GES DISC

AMSR-E/Aqua root zone soil moisture (LPRM) L3 1 day 25 km x 25 km descending and 2-Layer Palmer Water Balance Model V001 is a Level 3 (gridded) root zone soil moisture product. It is derived via the assimilation of Land Parameter Retrieval Model (LPRM)/Advanced Microwave Scanning Radiometer-Earth Observing System (AMSR-E)/NASA EOS Aqua surface soil moisture retrievals into the 2-Layer Palmer Water Balance Model, using a 1-dimensional, 30-member Ensemble Kalman filter (EnKF). The 2-Layer Palmer Water Balance Model was forced with meteorological forcing data obtained from the Air Force Weather Agency (AFWA). The EnKF seeks to (1) optimally combine soil moisture information derived from model forecast and satellite retrieval and (2) vertically extrapolate surface soil moisture retrievals into deeper root zone soil moisture predictions. There is one file per day (nighttime). The data set covers the period from June 2002 to December 2010.
