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

Weins Displacement Law
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

Solar radiation
Planetary 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 Re
2 = E 4 Re2
E = So/4 (1- )
____________ σT4 = ¼ So (1- ) =key radiant Eqn for climate
