Entropy balance of the earth: 0-dimensional, steady-state view


Energy balance
absorbed solar radiation = emitted terrestrial radiation
Q_1 = Q_2

Entropy balance
entropy of absorbed solar radiation + entropy production
= entropy of emitted terrestrial radiation
Q_1 / T_1 + (production) = Q_2 / T_2
T_1 ≒ 5800 K、 T_2 ≒ 255 K
