If the Earth was a rocky planet the Tmean.earth would be
Te.rocky.earth = 259,93 = 260 K
Isn't the Equation an adjustment on the already satellites measured planet mean temperatures?
A Planet Without-Atmosphere Effective Temperature Calculating Equation, the Te equation, which is based on the radiative equilibrium and on the Stefan-Boltzmann Law, and which is in common use right now:
Te = [ (1-a) S / 4 σ ]¹∕ ⁴
is actually an incomplete Te equation and that is why it gives us very confusing results.
Comparison of results the planet Te calculated by the Incomplete Equation, the planet Te calculated by the Surface Mean Temperature Equation, and the planet Tsat.mean measured by satellites:
