Enhancing reservoir water level time series in the Mekong river basin by improving area-elevation models and integrating multi-source satellite data

This is a reservoir water surface area and water levels dataset including 32 major reservoirs in Mekong River basin. For all the 32 reservoirs, water levels were inverted by using improved DEM-derived A-E model (combined with actual reservoir parameters limitation), improved DEM-derived A-E model (combined with actual reservoir parameters limitation) or satellite-derived A-E model based on the Landsat-derived surface area. An initial time series was constructed based on the optimal improved A-E model according to their own altimetry data availability. Then all the altimetry water levels (if available) were merged into the initial time series to construct the final time series water levels.Altimetry water level was preferred when the date of two datasets was identical.
