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.

The NOAA-21 platform collects Earth observation data to help scientists better understand climate trends and global biological productivity. Capitalizing on the success of the Suomi National Polar-orbiting Partnership (Suomi NPP) and NOAA-20, NOAA-21 features four similar instruments which take measurements related to atmospheric composition; carbon cycle, ecosystems, and biogeochemistry; climate variability and change; water and energy cycles; and weather. Joint Polar Satellite System-2 (JPSS-2) was renamed NOAA-21 after launch.
