Radiative Thermal Conductivity in Planetary Interiors


IT is customary to invoke radiative thermal conductivity as a mechanism for efficiently removing heat from the Earth's interior1. Clark2 derived the formula for radiative thermal conductivity in planetary conditions, where n is the refractive index, B is the blackbody function, γ is the radiation wavelength, α is the absorption coefficient and s is the backscattering coefficient. He used this relationship to estimate the radiative conductivity for a number of minerals by measuring α at room temperature and neglecting s (ref. 3).
