Provisional maps of thermal areas in Yellowstone National Park, based on satellite thermal infrared imaging and field observations

Satellite-based thermal infrared imaging provides an effective tool for mapping and monitoring the dynamic thermal areas of Yellowstone National Park, offering valuable insights into geothermal activity. This study utilized data from the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) to generate provisional maps of thermal areas, which were validated against field observations and high-resolution aerial photos. By minimizing solar heating contributions through winter night imaging, researchers quantified radiative heat flux and identified spatial extents of active thermal zones. These maps serve as a baseline for detecting future hydrothermal or volcanic anomalies, supporting infrastructure development, resource preservation, and visitor safety in the park.
