FireTIRS
Fire Thermal InfraRed Spectrometer

The Fire Thermal InfraRed Spectrometer (FireTIRS) is an airborne thermal infrared (TIR) imaging system developed for NASA’s FireSense Project. It collects TIR data from wildland fires across multiple bands in the 7.8 to 12.6 μm range, enabling the retrieval of trace gases, aerosols, and particulate matter. It is designed to be mounted on uncrewed aerial vehicles (UAVs) and can provide real-time fire data to support active fire detection, behavior assessment, and emissions monitoring. FireTIRS has a spatial resolution of 0.7 meters at an altitude of 100 meters.
