OPERA Dynamic Surface Water Extent from Sentinel-1 (Version 1) Dataset Release

[colleen]

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....
