"WebAn atmospheric layer of thickness, dz, and temperature, T, emits radiation following the Planck law: dI = yt dz = aa(z) B(v,T) dz where B(v,T) is the Planck function (in watts/m2/steradian). Since temperature and constituent density are functions of altitude, the thermal source is written as yt (v,T,z) = aa(z) B(v,T) " - Optical thickness formula
