Welcome to WreBigDL@Kyung Hee University!
Advancing Sustainable Water Management Through Validated Earth Observation Data
Our lab is dedicated to unravelling the complex impact of climate change on global water systems. By rigorously validating and improving Earth observation data, we aim to enhance our understanding and management of vital water resources. Our mission is to provide policymakers with robust, data-backed strategies for a more sustainable future.
