Featured Ocean Circulation Observation Method: SWOT
NASA's Surface Water and Ocean Topography (SWOT) platform monitors Earth’s surface water and measures how water bodies, such as lakes and rivers, change over time. SWOTS measures water surface heights 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.
