All NASA Polar Radiant Energy in the Far InfraRed Experiment (PREFIRE) datasets are now publicly available through NASA's Atmospheric Science Data Center (ASDC). This public release includes Level 1 Radiance, retrieved Level 2 products, Level 3 climatologies, and supporting auxiliary products. The Level 2 science data collections include a Cloud Mask, Spectral Flux, Surface Emissivity, and Atmospheric Properties (which provides surface temperatures, vertical temperature and water vapor profiles, and column water vapor), and the Level 3 products are 1°x1° gridded, monthly climatologies of Level 2 Surface Emissivity.
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.
