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

open access: yesGeophysical Research Letters, Volume 49, Issue 2, 28 January 2022., 2022
Abstract Monitoring water level changes is necessary to manage, conserve and restore natural, and anthropogenic lake systems. However, the in‐situ monitoring of lake systems is unfeasible due to limitations of costs and access. Furthermore, current remote sensing methods are restricted to large lakes and low spatial resolutions.
