That's why it passes through the air and heats the surface. Solar radiation is mostly visible and near IR, roughly half of which is absorbed at the Earth's surface, heating it.

(Anything absorbing radiation is thereby warmed.)

The only part of solar radiation which doesn't heat the Earth (either the air or surface) is the ≈30% which is reflected out into space.

That includes both the 10µm "atmospheric window" (most of that radiation escapes to space), and the 15µm band (where CO2 in the air absorbs it, warming the atmosphere).

Some warming of the atmosphere is from incoming solar radiation, but most warming of the atmosphere is directly or indirectly from the surface, by convection, radiation & the water cycle.

Radiation originating in the atmosphere is mostly from radiatively active "GHGs" like water vapor and CO2 (as well as water droplets in clouds, dust, etc.).

(That's not the case at high noon with the sun directly overhead, but radiation from the air warms the surface 24/7, and sunlight is daytime only.)
