Earth's Corrected Effective Temperature is Te.correct.earth = 210 Κ
To calculate Earth's Corrected 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 Corrected Effective Temperature Equation Te.correct.earth is:
Te.correct.earth = [ Φ (1-a) So /4σ ]¹∕ ⁴
Te.correct.earth = [ 0,47 (1-0,306) 1.361 W/m² /4*5,67*10⁻⁸ W/m²K⁴ ]¹∕ ⁴ =
Te.correct.earth = [ 0,47 (0,694) 1.361 W/m² /4*5,67*10⁻⁸ W/m²K⁴ ]¹∕ ⁴ =
Te.correct.earth = ( 1,957.367.636,68 )¹∕ ⁴ = 210,34 K
Te.correct.earth = 210,34 K
or
Te.correct.earth = 210 K
Te - planet effective temperature
Te = [ (1-a) S /4σ ]¹∕ ⁴
Te.correct - the planet corrected effective temperature
Te.correct = [ Φ (1-a) S /4σ ]¹∕ ⁴
Φ - is the solar irradiation accepting factor (it is the planet surface spherical shape, and planet surface roughness coefficient)
Φ = 0,47 - for smooth surface planets without atmosphere
Φ = 1 - for heavy cratered without atmosphere planets
Φ = 1 - for gases planets

Te.correct = [ Φ (1-a) S /4σ ]¹∕ ⁴
Tmean = [ Φ (1-a) So (β*N*cp)¹∕ ⁴ /4σ ]¹∕ ⁴
Or
Tmean = Te.correct * [ (β*N*cp)¹∕ ⁴ ]¹∕ ⁴

Conclusion:
We can calculate planet mean surface temperature obtaining very close to the satellite measured results.
Tmean = Te.correct * [ (β*N*cp)¹∕ ⁴ ]¹∕ ⁴
where [ (β*N*cp)¹∕ ⁴ ]¹∕ ⁴ - is the planet surface warming factor Warming Factor = (β*N*cp)¹∕₁₆
