NASA’s provision of the complete ESA Sentinel-1 synthetic aperture radar (SAR) data archive through the ASF DAAC is by agreement between the U.S. State Department and the European Commission (EC). As part of the Earth-observation Copernicus program, the Sentinel mission will provide scientists with accurate, timely, and easily accessible information to help shape the future of our planet.

Sentinel-1 – Applications
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.
Sentinel-1 – Observation Plans
The Sentinel-1 SAR observation plan implements a baseline pre-defined mission observation scenario, making optimum use of the SAR duty cycle within the technical constraints of the overall system. This scenario
Sentinel-1 – What is TOPSAR?
TOPSAR: Novel Radar Technique Sentinel-1 uses a cutting-edge SAR technique known as Terrain Observation with Progressive Scans SAR (TOPSAR). TOPSAR enables the Extra Wide Swath (EW) and Interferometric Wide Swath
