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.

Snow Cover Data Access and Tools
From discovery to visualization, data tools such as Application for Extracting and Exploring Analysis Ready Samples (AppEEARS), Snow Today, and Worldview guide users in making the most of snow cover data.

Featured Observation Method: VIIRS
The Visible Infrared Imaging Radiometer Suite (VIIRS) is an instrument aboard the joint NASA/NOAA Suomi National Polar-orbiting Partnership (Suomi NPP) and NOAA-platforms. VIIRS collects visible and infrared imagery along with global observations of Earth including cryosphere.
The algorithms VIIRS uses for snow cover and sea ice products are specifically designed to be compatible with similar products from older the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument, which supports comparison between datasets to facilitate long-term climate data records.

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.
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).
VIIRS I-band (375 m) Active Fire and Corrected Reflectance products are the newest near real-time products available through LANCE.
