to trap heat from the sun to shield the planet from harmful radiation and to disintigrate space debris before it reaches the surface
The layer of the sun's atmosphere that reaches farthest into space is called the Corona.
Radiation.
Electromagnetic radiation.
ozone
Most of the solar radiation is absorbed when it reaches the surface of the earth. Some of the solar radiation is also absorbed in the atmosphere.
It is absorbed by the atmosphere
When UV reaches earth, it interacts with ozone. It both creates and depletes ozone.
Some is absorbed by molecules in the atmosphere (such as ultraviolet absorption by ozone), some is absorbed on the surface, and some is reflected by clouds or the surface back into space. The surface will re-radiate much of the absorbed solar radiation as infrared (thermal) radiation, and some of this is then absorbed by atmospheric gases such as carbon dioxide and methane.
About 50% of the incoming solar radiation reaches the surface of the planet. The rest is reflected or absorbed by the atmosphere & clouds, and a small portion is reflected by the oceans and land.
Some of the most harmful radiation does not make it through the Earth's atmosphere.

Six percent is immediately reflected by the atmosphere.(Source: NASA.See the related question below.)
It's warmed from the surface. Shortwave radiation passes through the atmosphere, or at least about half of it, where it reaches the ground and is absorbed. The ground re-emits it at a longer wavelength, thereby warming the lower atmosphere.
Heat from the sun reaches you from radiation.
