TIRS (Thermal Infrared Sensor)

The Thermal Infrared Sensor (TIRS) is a device used in satellites to detect heat energy emitted from the Earth's surface. It captures thermal radiation in the infrared part of the electromagnetic spectrum, allowing it to measure temperature variations even through clouds or darkness. This information helps scientists monitor land and water temperatures, identify environmental changes, and track phenomena like wildfires or urban heat islands. TIRS provides valuable data for climate studies, agriculture, and disaster response, offering a detailed thermal map of the Earth's surface from space.
