A Kalman Filter Approach for Estimating Daily Discharge Using Space‐Based Discharge Estimates
Water Resources Research, Volume 61, Issue 8, August 2025.Abstract The SWOT satellite mission is the first to conduct a global survey of the Earth's surface waters, measuring water surface height, river width, and water surface slope, based on which river discharge is estimated. At mid‐latitudes, the repeat orbit design of SWOT only allows a sampling of twice per repeat cycle, which is considered too low for ...
