Thermal infrared data

Definition

Thermal infrared data refers to the information collected in the thermal infrared wavelength range, typically from 8 to 14 micrometers, which is crucial for assessing the thermal properties of planetary surfaces and atmospheres. This type of data allows scientists to identify surface temperature variations, detect mineral compositions, and understand heat flow processes on planetary bodies. By capturing emitted radiation, thermal infrared data provides insights into geological and atmospheric phenomena across different celestial environments.
