This chapter presents an overview of the most commonly used spaceborne sensors for thermal infrared research applications. There is a large fleet of international sensors available which allow for the acquisition of data in the thermal infrared. Depending on spatial coverage, some sensors are more suitable for mapping large areas, while others support observations at a local scale. Temporal resolution defines whether temperature patterns or phenomena can be monitored on a daily, weekly, monthly, or even only an annual basis. A wide variety of thermal sensors will be introduced in overview tables. However, as certain sensors with thermal infrared bands have established themselves as ‘work horses’ for certain types of applications, they will be especially highlighted and presented in depth. A comprehensive overview of typical thermal infrared application studies and the sensors particularly favored rounds off this chapter.
