The Synthetic Aperture Radar (SAR) aboard the ESA (European Space Agency's) Sentinel-1A/B satellites provides continuous all-weather, day-and-night land imagery. SAR images can be used to see through clouds and vegetation to identify flooded areas caused by seasonal changes, storms, and other events.
