one part is absorbed in the ozone layer, another part is reflected by clouds and the surface of the earth, the major part is absorbed by the surface of the earth.

one part is absorbed by the atmosphere, almost all of the incoming radiation reaches the surface of the earth, where it is completely absorbed, leading to maximum temperatures at the around.

the major part remains in the stratosphere, where the ozone layer is an effective absorber of solar radiation, temperatures in the ozone layer are therefore similar to surface temperatures.

the major part is absorbed by atmospheric gases and clouds, the temperature rise in the affected layers leads to long wave terrestrial radiation.

The conduction of heat between the surface and the air in contact with it creates turbulent mixing, which is themost significant component in the transfer of heat to or from medium levels in the Earth's atmosphere.

The primary process involved in the transfer of heat upwards from the surface of the Earth into the upper atmosphere is turbulence, which exists throughout the Earth's atmosphere.

The air at the surface can be cooled or warmed by the process of conduction, which is the molecular transfer of heat between the surface and the air in contact with it.

Turbulent mixing contributes mainly to the transfer of heat in the Earth's atmosphere, in the horizontal plane, but has little effect in the warming or cooling of the atmosphere in the vertical plane.
