WebInfrared light, or infrared radiation, has wavelengths longer than visible light and is usually experienced as heat. Infrared radiation is invisible to the human eye, but to night vision … WebFor standard IR satellite imagery this wavelength is 10.7 microns. The satellite radiometer therefore captures a grid of radiation intensity values at 10.7 microns. Next, these radiation values are converted into temperatures using equations derived from Planck's Law and Kirchhoff's Law. These satellite derived temperature values are formally ...
