We are in the process of migrating all NASA Earth science data sites into Earthdata from now until end of 2026. Not all NASA Earth science data and resources will appear here until then. Thank you for your patience as we make this transition.

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).
Recently released datasets from the SWOT mission provide scientists with previously unavailable measurements of Earth's surface water.

Learn how to discover, access, and use Surface Water and Ocean Topography (SWOT) mission data and how these data can lead to new, innovative science and applications in the world of water.
Join us on Wed., July 30 at 2:00 p.m. EDT (-04:00 UTC) to explore SWOT hydrology data collections of rivers and lakes, and to learn how to work with SWOT hydrology data using tools provided by both NASA's PO.DAAC and the USGS.
Hydrocron enables users to receive all Surface Water and Ocean Topography (SWOT) observations for a specific river ID within a specified date range.
