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 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 = 254 K (https://nssdc.gsfc.nasa.gov/planetary/factsheet/earthfact.html)

Then they compared the Te.earth = 254 K with the measured by satellites Tsat.mean.earth = 288 K (https://nssdc.gsfc.nasa.gov/planetary/factsheet/)

The difference of 288 K - 254 K = Δ34 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.
