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 StefanBoltzmann 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 WithoutAtmosphere Corrected Effective Temperature Equation Te.correct.earth is:
Te.correct.earth = [ Φ (1a) So /4σ ]¹∕ ⁴
Te.correct.earth = [ 0,47 (10,306) 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 = [ (1a) S /4σ ]¹∕ ⁴
Te.correct  the planet corrected effective temperature
Te.correct = [ Φ (1a) 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 (1a) S /4σ ]¹∕ ⁴
Tmean = [ Φ (1a) 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
Earth withoutatmosphere and higher than Moon Albedo (a=0,306), when measured by NASA the Earthen equilibrium temperature should be even less than 210K.
Why is (for Earth Te =255K) NASA calculation so inaccurate – too high?
And Tse – Te = 288K  210K = 78C the measured GHE then?
There is a deeply established concept that "The avg. planetary temperature changes with rotation speed rising to equilibrium temperature as the spin rate increases.”
This concept determines the planet effective (equilibrium) temperature Te as a kind of cutoff point. This concept states, planet avg. temperature (the avg. surface withoutatmosphere temperature) cannot exceed the planet effective (equilibrium) temperature Te, no matter how fast the planet rotational spin.
What we actually observe is the following:
The avg. planetary temperature changes with rotation speed rising to equilibrium temperature and overgoing it as the spin rate increases...
Notice, there is a limit to the avg. planetary temperature rise, but it is not the Te or the Te.corrected.
Also the calculated Te and Te.corrected assume planet having reached uniform surface temperature, which is impossible, because planets always are solar irradiated by one side, and, no matter how fast they rotate, the solar lit side is always warmer…
And there are not measured data for planets' blackbody temperatures, because planet blackbody temperatures, (either the not corrected Te and the corrected Te.corrected) are only mathematical abstractions.
(Orphan planet is a planet not having a mother star to orbit).
Orphan planet is not solar energy irradiated, therefore it has a surface temperature because of its own internal heat sources.
Two orphan planets may have the same average surface temperature, but the more differentiated surface temperatures orphan planet has the greater amount of IR outgoing radiative energy the orphan planet emits. (It is in accordance with StephanBoltzmann emission law nonlinearity.)
Let’s consider two orphan planets emitting the same amount of IR outgoing radiative energy. The more surface temperatures differentiated orphan planet – the colder on average surface temperature planet.
An orphan planet with uniform surface temperature would have approached the planet effective radiative temperature Te. Te is the highest possible average surface temperature for an orphan planet.
When rotating the planet surface has larger surface areas get exposed to solar flux in unit of time. When rotating faster – more areas get exposed.
Since surface's the slower ability to accumulate HEAT than emit IR, the faster rotating planet is capable to TRANSFORM larger amounts of SW EM radiative solar energy into HEAT.
Thus the faster rotating planet (everything else equals) is capable to accumulate larger amounts of transformed into HEAT solar EM energy.
That is what makes a faster rotating planet on average surface a warmer planet.
The planet specular reflection was neglected
For planets and moons with smooth surface, the surface’s specular reflection is not negligible.
The smooth surface planets and moons have a very strong the surface’s specular reflection.
The specular reflection is not included in albedo.
So we had (for those planets and moons with smooth surface, and, therefore, with surface’s strong specular reflection), we had to correct their respective the planet effective temperature Te.
Correcting the Effective temperature (Te) formula:
Te = [(1a) S /4σ ]¹∕ ⁴ (K) (1)
We insert the
Φ – the solar irradiation accepting factor (the planet spherical shape and planet surface roughness coeficient)
Φ =0,47 for smooth surface planets and moons
Φ =1 for heavy cratered (rough surface) planets and moons
Te.correct = [Φ(1a) S /4σ ]¹∕ ⁴ (K) (2)
Te.correct, for the smooth surface planets and moons, has a much lower, than Te, numerical values.
–
Thus, for Earth, the Te =255K, when corrected,
became Te.correct =210K.
But, notice, it is very important:
The planet effective temperature, even when it is corrected, the planet effective temperature does not exist, the planet effective temperature is a mathematical abstraction.

Opponent:
“The specular reflection is not included in albedo.”
Evidence?
Answer:
Thank you for your response:
“The specular reflection is not included in albedo.”
“Evidence?”

Let's demonstrate
“The specular reflection is not included in albedo.”
on Moon's Te example:
Moon’s Te = 270,4 K
Moon’s Te.correct = 224 K (corrected for smooth surface planets and moons with
Φ = 0,47)
Moon’s satellite measured average surface temperature Tsat = 220 K.
–
When comparing those three temperatures
Te = 270,4 K (calculated with moon’s Albedo
a =0,11)
Te.correct = 224 K (calculated with moon’s Albedo
a =0,11
and Φ =0,47 )
And the measured Tsat =220 K,
The theoretical Te.correct = 224 K is very much close to the satellite measured
Tsat = 220K.
On the opposite, the Te = 270,4 K is very much higher, than the satellite measured
Tsat =220 K.
–
And this is an undeniable evidence of the fact that
The specular reflection is not included in albedo.
********
Another undeniable evidence of the fact that the
specular reflection is not included in albedo.
The Planet Mars’ Te =210K
and Planet Mars’ Tsat =210K
COINCIDENCE!
Planet Mars’ Te =210K is calculated by the use
of Mars’ Albedo a =0,25
Planet Mars’ Tsat =210K is the Mars’ satellite measured average surface temperature.
Those two temperatures, the theoretically calculated 210K and the measured one 210K there is not any physical explanation of them to coincide, except of the Mars’ specular reflection being ignored.
Why the specular reflection is ignored – because it was considered too small.
And yes, there are planets and moons where the specular reflection is too small to take in consideration. For them Φ =1.
But there also are the smooth surface planets and moons with very strong specular reflection.
Those planets and moons are:
Mercury
Earth
Moon
Mars
Europa
Ganymede
And for those planets and moons the Φ =0,47
Thus for the planet Mars, instead of Te =210K
it is Te.correct =174K
