Planet Mars black-body temperature (effective temperature) Te misfortunate coincidence

We have calculated the Corrected Effective Temperature for Mars Te.correct.mars = 174 K

But let's see what happened when the Effective Temperature of Mars was not yet corrected. Te.mars = 209,8 K (https://nssdc.gsfc.nasa.gov/planetary/factsheet/marsfact.html)

Tsat. mean.mars = 210 K (https://en.wikipedia.org/wiki/Mars)

We have here planet Mars mean temperature measured by satellites:

Tsat.mean.mars = 210 K

We have the Mars black-body temperature

Te = 209,8 K

These temperatures the Tsat.mean.mars = 210 K and the black-body temperature Te.mars = 209,8 K are almost identical.

These two very important for planet Mars temperatures are almost identical, but it is a coincident.

It is a coincident, but with very important consequences.

Let's explain:

Tsat.mean.mars = 210 K measured by satellites is almost equal with Te.mars = 209,8 K

When measuring by satellites the Tsat.mean.mars = 210 K and calculating Mars black-body temperature Te.mars. = 209,8 K scientist were led to mistaken conclusions.

First they concluded that the planet's effective and planet's without-atmosphere mean temperatures should normally be equal, which is wrong.

Secondly they concluded that Earth without atmosphere should have an average surface temperature equal to the black-body temperature (effective temperature), Te.earth = 255 K (https://nssdc.gsfc.nasa.gov/planetary/factsheet/earthfact.html)

Then they compared the Te.earth = 255 K with the measured by satellites Tsat.mean.earth = 288 K (https://nssdc.gsfc.nasa.gov/planetary/factsheet/)

The difference of 288 K - 255 K = Δ33 oC was then attributed to the Earth’s atmosphere greenhouse warming effect.

Now we have the Mars Corrected Effective Temperature

Te.correct.mars = 174 K.

The fact that the Corrected Effective Temperature of Mars is Te.correct.mars = 174 K, which is not even close to the satellite measured Tsat.mean.mars = 210 K debunks the above syllogism that the planet the calculated black-body temperature Te (effective temperature) is equal to the planet without atmosphere mean surface temperature Tmean.

The above wrong syllogism happened because of the wrongly estimated Mars black-body temperature.

It was calculated assuming planet absorbing incoming solar energy as a disk. We know now that planet absorbs the incoming solar energy as a sphere, and not as a disk.
