Featured Sea Surface Topography Observation Method: SWOT

NASA's Surface Water and Ocean Topography (SWOT) platform monitors Earth’s surface water and measures how water bodies, such seas and oceans, change over time. SWOTS measures water surface heights using its primary instrument, the Ka-band Radar Interferometer (KaRIn).
