ASDC has released Level 1, 2, and 3 datasets from the Polar Radiant Energy in the Far InfraRed Experiment (PREFIRE) mission. These datasets provide unprecedented measurements of far-infrared radiation in polar regions, enabling global researchers to study polar energy budgets, seasonal variations, and surface-cloud interactions with greater precision. This milestone supports enhanced Earth system modeling and understanding of polar climate processes.
