Synthetic aperture radar NISAR title imageASF To Distribute NISAR Satellite Imagery

Unprecedented, detailed synthetic aperture radar (SAR) views of Earth from the NISAR satellite, to be launched in 2021, will be distributed by the ASF DAAC. NISAR data will help scientists better understand our planet's processes and changing climate, and aid resource and hazard management. One example came in May in the aftermath of Cyclone Roanu, which claimed over 100 lives in Sri Lanka and Bangladesh and left tens of thousands in need of aid. Data from Sentinel-1A were used to generate flood maps.

“ASF is pleased to be playing such a key role in this important mission,” said ASF Director Nettie La Belle-Hamer. “We look forward to adding NISAR data to the data holdings and support we provide for the science community.”

Sentinel-1A & 1B Data Available 

Synthetic aperture radar (SAR) data from both of Sentinel-1's twin satellites are now added daily to the ASF archive, comprising a complete historical archive of Sentinel-1 SAR data processed by the European Space Agency (ESA).

With ongoing, all-weather, day-and-night, global Earth data, the Sentinel-1 mission facilitates monitoring and mapping of sea ice, oil-spills, land-surface motion, humanitarian crises, and more.
