Because the atmosphere is nearly transparent to wavelengths in the range 8 to 13 µm (atmospheric window) for a clear sky, it is possible to cool down a surface even during a sunny day. This model compares the temperature distribution on a concrete block exposed to ambient and solar radiation on his upper surface when this surface is a black surface and when it has radiative cooling properties. Convective cooling is not accounted for. This model couples the Heat Transfer in Solids interface with the Surface-to-Surface Radiation interface. 4 spectral bands are used to model the wavelength dependency of the irradiation, of the surface emissivity and of the sky emissivity.
