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.

Water Management Data Access and Tools
NASA has water management datasets that help researchers characterize the particular makeup of the air we breathe. Access a range of data and data tools such as AppEEARS, FIRMS, and Giovanni to make the most of water management data.

Featured Water Management Observation Method: MODIS
The Moderate Resolution Imaging Spectroradiometer (MODIS) continually collects data with global coverage every one to two days. Its exceptionally broad spectral range enables MODIS data to be used in studies across numerous disciplines, including changes in land cover and land use, and flood detection. An important attribute of MODIS data is the availability of MODIS data products in real-time and near real-time. Direct broadcast stations around the world download raw MODIS data in real-time directly from the satellite, while NASA’s Land, Atmosphere Near Real-time Capability for EOS (LANCE) provides several MODIS products within three hours of satellite observation.
Images captured on Sep 6 and Sep 4, 2021, by the MODIS instrument aboard the Terra satellite.
New Near Real-Time (NRT) Global Flood Mapping product from LANCE will continue production of data critical for detecting floods around the globe.
8 MIN READ
The Visible Infrared Imaging Radiometer Suite (VIIRS) will help ensure continuity of Earth observations after the upcoming retirement of the Moderate Resolution Imaging Spectroradiometer (MODIS).
