SWOT is a NASA-CNES Earth science mission designed to survey the height of water across more than 90 percent of Earth's surface. Its wide-swath Ka-band radar interferometer maps oceans and inland waters at scales that help researchers study circulation, freshwater change, floods, droughts, and coastal processes. Canada and the United Kingdom contributed mission hardware.
