The surface of the Moon is characterized as an evacuated particulate medium in which radiative heat exchange between solid surfaces plays a decisive role in determining the transient behavior of the apparent temperature. A simple model is developed which permits quantitative comparisons with lunar surface temperature variations, observed in the 8-12 micron band, both during a lunation and a lunar eclipse. Thermal properties and certain surface characteristics are thereby inferred, including an effective microstructure scale of the order of 0.1 mm. Author
