This formula collapses the 'Greenhouse effect' and proves it does not exist;

Te = ∜0.523 x Tv

The surface temperature on Earth is easily calculated - from Venus.

The fourth-root of the TSI (Total Solar Irradiance) difference times the temperature in the Venus atmosphere at 1atm = Earth's temperature

No need to correct for greenhouse gasses!
