We are in the process of migrating all NASA Earth science data sites into Earthdata from now until end of 2026. Not all NASA Earth science data and resources will appear here until then. Thank you for your patience as we make this transition.

Floods Data Access and Tools
From discovery to visualization, data tools such as the Dartmouth Flood Observatory (DFO), HYDrologic Remote Sensing Analysis for Floods (HYDRAFloods), and the Spatial Data Access Tool (SDAT) guide users in making the most of flood data.

Featured Floods Observation Method: Sentinel-1 C-SAR
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.
Sentinel-1 synthetic aperture radar (SAR) data are used to create maps of surface water extent for research, planning, and disaster response.
The Observational Products for End-Users from Remote Sensing Analysis (OPERA) Dynamic Surface Water eXtent (DSWx) product suite, a Satellite Needs Working Group solution, maps spatial extent of surface water.
