Here is a constraint that shapes many flood risk systems around the world: The worst flood events and the worst cloud cover arrive together. Optical satellites (the ones that produce the familiar photos most people picture when they think of satellite observation) can be blocked by cloud cover. During an active monsoon flood, a cyclone landfall, or a sustained rainfall event, the scenes that matter most are precisely the ones optical satellites cannot capture. Synthetic Aperture Radar (SAR) changes that calculus entirely. SAR satellites operate in the microwave portion of the electromagnetic spectrum. They send signals down to Earth that can cut through clouds and other optical obstacles, enabling all-weather, day-night imaging. The European Space Agency - ESA's Sentinel-1 mission provides SAR-based global coverage with a revisit time of 6-12 days, spatial resolution of 5-20 meters, and a swath width of 250 kilometers. The #Copernicus Global Flood Monitoring service, launched in 2021 and built on Sentinel-1 imagery, processes all land images acquired fully automatically in near-real time, typically delivering flood maps within five hours of image acquisition. GreenAnt’s #Desidera platform integrates SAR satellite imagery into its range of climate analytics capabilities. That means uninterrupted, reliable, cutting-edge outputs for your organization.
