The PO.DAAC is pleased to announce the release of the validated OPERA Dynamic Surface Water Extent from Sentinel-1 (DSWx-S1 Version 1) Dataset. OPERA DSWx-S1 provides near-global geographical mapping of surface water extent over land at a spatial resolution of 30 meters over the Military Grid reference System (MGRS) grid system, with a temporal revisit frequency between 6-12 days.
Using Sentinel-1A radar observations, DSWx-S1 maps open inland water bodies greater than 3 hectares and 200 meters in width, irrespective of cloud conditions and daylight illumination that often pose challenges to optical sensors. Forward production of the DSWx-S1 data record began in September 2024. The data are freely available from PO.DAAC.
OPERA, managed by the Jet Propulsion Laboratory and funded by the Satellite Needs Working Group, is creating remote sensing products to address Earth observation needs across U.S. civilian federal agencies.
Datasets included in this release are listed below with their digital object identifiers linked to the PO.DAAC Web Portal.
