Retrieval of Simultaneous Water‐Level Changes in Small Lakes With InSAR

Abstract Monitoring water level changes is necessary to manage, conserve and restore natural, anthropogenic lake systems. However, the in‐situ monitoring of systems unfeasible due limitations costs access. Furthermore, current remote sensing methods are restricted large lakes low spatial resolutions. We develop a novel approach using subsequential pixel‐wise observations Sentinel‐1B sensor based on interferometric synthetic aperture radar detect in small lakes. used 24 ungauged Cajas Massif system Ecuador for development validation. found Differential Interferometric Synthetic Aperture Radar (DInSAR)‐derived across be consistent with precipitation, capturing peak wet seasons. accumulated could explained by differences area among Although limitations, this study shows underutilized potential DInSAR understand data availability.
