Airborne and satellite Thermal Infrared (TIR) scanner systems are important tools in remote sensing that measure the thermal energy emitted by objects on the Earth’s surface. Unlike visible and near-infrared sensors that rely on reflected solar radiation, TIR systems detect emitted radiation, which is directly related to the temperature and emissivity of surface materials. This capability allows them to operate both during the day and at night, making them highly useful for continuous environmental monitoring. Airborne TIR scanner systems are mounted on aircraft and provide high spatial resolution data due to their relatively low altitude. These systems are flexible in operation, allowing for targeted data collection over specific areas at desired times. Airborne scanners typically operate in the thermal infrared region between 8 to 14 micrometers, which corresponds to the atmospheric window where absorption is minimal. The high-resolution data obtained from airborne systems is useful in applications such as urban heat island studies, forest fire detection, geothermal exploration,
