As an advanced radar mission, Sentinel-1 can image the surface of Earth through cloud and rain and regardless of whether it is day or night. This makes it an ideal mission, for example, for monitoring the polar regions, which are in darkness during the winter months and for monitoring tropical forests, which are typically shrouded by cloud.
Over oceans, the mission will provide imagery to generate timely maps of sea-ice conditions for safe passage, to detect and track oil spills and to provide information on wind and waves, for example. Over land, Sentinel-1’s systematic observations will be used, for example, to track changes in the way the land is used and to monitor ground movement. Moreover, this new mission is designed specifically for fast response to aid emergencies and disasters such as flooding and earthquakes.
