In this webinar, speakers from NASA’s Atmospheric Science Data Center (ASDC) and the Polar Radiant Energy in the Far-InfraRed Experiment (PREFIRE) mission illuminate how ASDC serves as the gateway to critical polar radiation data that advances our understanding of climate dynamics in Earth's most sensitive regions. Speakers provide an overview of ASDC's mission and capabilities, followed by essential background on the PREFIRE mission, which provides unprecedented measurements of outgoing longwave radiation (OLR). Participants will discover how PREFIRE's CubeSat constellation captures far-infrared emissions from polar regions, filling critical gaps in our understanding of Earth's radiation budget. A series of data discovery and data access demonstrations showcase not only ASDC's comprehensive suite of cloud-based tools and services but also highlight NASA Worldview for visualization, Earthdata Search for data discovery, OPeNDAP for programmatic access, Harmony for data processing, and integration of AWS cloud with QGIS and ArcGIS Pro for advanced geospatial analysis. An interactive Jupyter notebook demo using Python shows how to visualize PREFIRE data through the earthaccess library and other open-source tools, empowering researchers to conduct their own polar radiation analysis. The session concludes with curated resources for continued PREFIRE research and an interactive Q&A segment.
