Methodology Overview
			• Use a LSM to generate a “truth” data set that provides both surface soil moisture “observations” and evaluation data. • Degrade the land surface forcing data and initial conditions to simulate uncertainties in this data (assume a perfect model). • Run the LSM with degraded data. • Run the LSM with degraded data and assimilate the “observations” with various spatial and temporal resolutions imposed using the extended Kalman filter. • Compare with the “truth”.
