  2. Blackbody radiation: Monochromatic irradiance of radiation emitted by a blackbody at (absolute) temperature T is given by: = When C2 = 3.74 x 10-16Wm2 C2 = 1.44 x 10-2 mok Blackbody radiation is isotopic Eλ C1 λ-5 e(-C2/λT) λm = Weins Displacement Law

  3. The Maximum wavelength of emission of the Sun is 0.475 μm (475 nm) What is the “color temperature” of the sun? ­­­­­­­­­­ Integrating the Planck blackbody irradiance over all wavelengths E* =σT4 σ is the Stefan – Boltzman constant 5.67 x 10-8wm-2degree-4

  4. Solar radiation Let So be solar irradiance incident on Earth (=1380 wm-2)-the solar “constant”, Re is the radius of Earth, is alkedo. At equilibrium, Incoming = Outgoing (1- ) So Re2 = E 4 Re2 E = So/4 (1- ) ____________ σT4 = ¼ So (1- ) =key radiant Eqn for climate Planetary radiation
