Scwartzchild’s Equation – RTE for no-scattering L0: radiance emerging from the Earth’s surface tl(z): vertical transmittance from height z to space. T(z): vertical profile of temperature Bl[T(z)]: Planck function profile. Weighting function - W
Idealised transmittance profiles and weighting functions at two frequencies with different absorption coefficients. Vertical coordinate: scale height = - loge(pressure).
Left-illustrating the attenuation of upwelling radiation emitted from three heights in the atmosphere. Right-the corresponding vertical profile of the contribution to the emission to space.
