Your “absolutely nothing wrong with it” paper clearly claims that the Earth’s surface receives thermal energy which is radiated from the atmosphere.
This would be a violation of the Second Law of Thermodynamics.
It does not happen; it cannot happen. Your paper has no veracity.
I have said it many times and linked papers such as this* peer-reviewed published German paper which clearly explains the breach of the Second Law by such assumptions as your linked paper clearly stated. They put their foot in it.

“Unfortunately, there is no source in the literature, where the greenhouse effect is introduced in harmony with the scientific standards of theoretical physics.”
