Mars' Effective Temperature calculation Te.mars = 173,77 K

Mars' Effective Temperature is Te.mars = 173,77 Κ

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

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

So = 1.361 W/m², solar costant

R - is the distant from the sun in AU (astronomical units)

(1/R²) = (1/1,524²) = 1/2,32 

Mars has 2,32 times less solar irradiation intensity than Earth has

Mars’ average surface albedo:

amars = 0,25

Mars is a rocky planet, Mars’ surface irradiation accepting factor: Φmars = 0,47

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

 

Mars' Effective Temperature Equation Te.mars is:

 

Te.mars = [ Φ (1-a) So (1/R²) /4σ ]¹∕ ⁴

 

Te.mars = [ 0,47 (1-0,25) 1.361 W/m²*(1/2,32) /4*5,67*10⁻⁸ W/m²K⁴ ]¹∕ ⁴ =

=( 911.771.916,62)¹∕ ⁴ = 173,77 K

Te.mars = 173,77 K
