Atmospheric effects on incoming solar radiation

Hello everyone in my research I will be looking for more information about the incoming solar radiation on the earth's atmosphere

Three atmospheric effects processes transform the amount of solar radiation arriving at the thin layer of gases that surrounds the earth intending for the earth's surface.These processes act on radiation when it acts reciprocally  with gases and suspended particles found in the atmosphere.The process of scattering occurs when small particles and gas molecules spread part of incoming solar radiation in proceeding directions in the absence of any alteration to the wavelength of the electromagnetic energy.  

Scattering does  however makes smaller  amount of incoming solar radiation arriving at the earth's surface.A significant regulation of scattered shortwave solar radiation is redirected back into space.The amount of scattering that takes place is determined by two factors namely; 

  1. Wavelength of incoming solar radiation.
  2. Size of scattering particles or gas molecules.

In the thin layer of gas that surrounds the earth,being present of a large of particles with a size of about 0.5 microns occurs to shorter wavelengths being  more favorably scattered.This factor also results our sky to look blue because this colour have a similar similarity to those wavelengths that are best diffused.If scattering did not occur in our atmosphere the day light sky could become black.

In this illustration we see that three particles send light rays of into different directions.Scattering does not change the striking light rays wavelength or the quality of being intense.
