Surface temperatures of the Moon: measurements with commercial infrared cameras

Information about the surface temperature of the Moon is contained in its emitted thermal infrared (IR) radiation. In this paper, we discuss estimates for surfaces temperatures of the Moon across its disc, as well as the potential to extract quantitatively correct values for the maximum temperatures through measurements with simple hand-held commercial IR cameras. Exemplary measurements reveal suitable conditions and necessary corrections due to atmospheric attenuation. The topic fits well into undergraduate courses on optics or more specifically on IR technologies.
