Lakes/Reservoirs Data Access and Tools
NASA has lakes and reservoirs datasets that help researchers explore the size, health and other aspects of waterbodies. Access a range of data and data tools such as AppEEARS, HEG, and the MODID/VIIRS Subsetting Tools Suite to make the most of lakes and reservoirs data.
Featured Lakes/Reservoirs 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.
