Yes, the energy doesn't pass through the air like you claim, it is absorbed. Energy is absorbed by the Nitrogen molecules. The increased energy causes the electrons to jump to a higher orbital. When they return to their lower orbital, they omit blue light. Do some research. The amount of solar radiation that actually reaches the Earth's surface is actually VERY small. Solar Energy: From Sun to Earth

The other 30% gets reflected back, by clouds, and light colored surfaces, like snow and ice.

I never claimed it passes un altered through the air, on the contrary, i said 20% gets absorbed by the atmosphere.

What is the exact % of solar radiation that reaches the surface then? Your article refers to reflection and diffusion.
