Air in the atmosphere does not get heated up due to a combination of reasons. Firstly, the atmosphere reflects most of the heat back and only a portion of heat from Sun's radiation makes it through.
The heat that does get through heats up the Earth more than the air in the atmosphere because in the air, the heat gets converted into kinetic energy of the molecules. As the molecules are not densely packed, they are able to absorb the energy which increases their kinetic energy and they move about expending this energy. The same is not possible in the case of land..

Radiation does not require a medium to travel but rather this does not suggest that it can just increase without a medium!
Radiation while going through earth's environment Additionally warms up the air (the medium), be that as it may, the conductive and convective warmth exchange close to the earth's surface role in keeping up the temperature. This warms up the medium more close to the world's surface and causes a flow of air.
