Cloud cover influences the amount of solar radiation that reaches Earth's surface because solar radiation cannot reach earth if there is tons of clouds blocking the way
The solar radiation that reaches the earths surface from the sun is called INSOLATION
Reflected.
The Earth is warmed mainly by solar radiation. It is measured in kilowatt-hours per square meter per day. This is called incident solar radiation or insolation.
The wavelength is longer. Energy is re-radiated by the Earth as infrared radiation (heat).

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.

About 6% of incoming solar radiation is reflected back into space from the atmosphere and 4% by the surface of the earth.Incoming solar radiation: 100%Reflected by the atmosphere: 6% : Absorbed by the atmosphere: 16%Continuing incoming solar radiation: 78%Reflected by clouds: 20% : Absorbed by clouds: 3%Continuing incoming solar radiation: 55%Reflected by the earth's surface: 4% : Absorbed by the earth's surface (lands and oceans): 51%

From the surface. Solar radiation is absorbed by the surface and emitted at a longer wavelength, which is essentially heat.
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.
Since stratospheric ozone is produced by solar UV radiation, one might expect to … Consequently, unabsorbed and dangerous ultraviolet-B radiation is able to reach the Earth's surface .
