Snow/Ice Albedo Data Access and Tools
NASA has snow and ice albedo datasets that help researchers measure how much frozen surfaces reflect solar radiation. Access a range of data and data tools such as AppEEARS, Worldview, and Giovanni to make the most of snow and ice albedo data.
Featured Snow/Ice Albedo Observation Method: MODIS
The Moderate Resolution Imaging Spectroradiometer (MODIS) gathers data in 36 spectral channels and can survey the entire Earth every one to two days. The instrument flies aboard NASA's Aqua and and Terra platforms. MODIS data can be used for a broad range of Earth science observations, including surveys of snow and ice cover across the planet with resolutions ranging from 250 to 1000 meters.
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).

Join us to learn how to discover, subset, access and visualize both MODIS and VIIRS data products using a suite of user-friendly tools developed by NASA's ORNL DAAC.
