Featured Total Surface Water Observation Method: SWOT
NASA's Surface Water and Ocean Topography (SWOT) platform monitors Earth’s surface water using its primary instrument, the Ka-band Radar Interferometer (KaRIn).
Recently released datasets from the SWOT mission provide scientists with previously unavailable measurements of Earth's surface water.
