An analytical theory is proposed for the earth-atmosphere system at its equilibrium surface temperature, 289.16 K. A non-linear relation is formulated between atmospheric absorption and atmospheric radiation by modifying Kirchhoff's law on thermal radiation. For the first time, the Global Energy Balance can be realized in a wide range of atmospheric absorptivity, transmittance, and surface emissivity. It is revealed that atmospheric radiation becomes negative once the atmospheric absorptivity is below its threshold value. It is proven that the upward cumulative long-wave atmospheric radiation spontaneously increases from 3.8 W [m.sup.-2] to 199.4 W [m.sup.-2] as the long-wave atmospheric absorptivity increases from 0.4 to 1.0 whilst the long-wave atmospheric transmittance decreases from 0.6 to 0.1., 1 Introduction For over a century, many attempts have been made to balance the global energy budget, both at the top of the atmosphere (TOA) and at the Earth's surface [...]
