Earth’s Without-Atmosphere Effective Temperature calculation Te.earth = 210,34 Κ

Earth's Effective Temperature is Te.earth = 210,34 Κ

To calculate Earth's Effective Temperature we should use the following data values

σ = 5,67*10⁻⁸ W/m²K⁴, the Stefan-Boltzmann constant

Φ = 0,47 solar irradiation accepting factor (dimensionless)

a = 0,306 Earth's average albedo

So = 1.361 W/m², solar flux on the top of the Earth's atmosphere

Earth’s Without-Atmosphere Effective Temperature Equation Te.earth is:

Te.earth= [ Φ (1-a) So /4σ ]¹∕ ⁴

Τe.earth = [ 0,47 (1-0,306) 1.361 W/m² /4*5,67*10⁻⁸ W/m²K⁴ ]¹∕ ⁴ =

Τe.earth = [ 0,47 (0,694) 1.361 W/m² /4*5,67*10⁻⁸ W/m²K⁴ ]¹∕ ⁴ =

Τe.earth = ( 1,957.367.636,68 )¹∕ ⁴ = 210,34 K

Te.earth = 210,34 K
