Abstract
In order to address the need for daily information regarding wildfire activity across large geographic areas to support wildfire assessment and management, the USDA Forest Service has implemented the use of synoptic view, high temporal resolution satellite sensors. In 2000, the USDA Forest Service Remote Sensing Applications Center (RSAC) began to investigate the utility of the imagery and derived products provided by the Moderate Resolution Imaging Spectroradiometer (MODIS) for daily fire detection and monitoring. The effort has since evolved into the USDA Forest Service MODIS Active Fire Mapping Program that supports Forest Service and interagency wildfire management at the regional and national levels. This paper describes the characteristics of the MODIS sensor flying onboard NASA’s Earth Observation System (EOS) satellites Terra and Aqua and its utility for daily wildfire detection and mapping. Furthermore, discussion is provided on the systematic, operational approach developed through coordination between NASA, the MODIS fire and thermal anomalies product team and RSAC to process thermal and reflective image data to provide timely fire-related geospatial products. This collaborative approach serves as an operational model for future satellite instruments capable of fire detection and characterization.
