Abstract
In this project we have review the role of aerosols in the Earth's atmosphere. We considered an important source of aerosol particles in the atmosphere are the processes of physical and chemical interaction of substances, in particular the interaction of the main gas, and water vapour. In our work aerosol particles interact with sun radiation by reflection, scattering, or absorbing incoming radiation and the amount of reflection, scattering or absorbing we can explain the effect of aerosol in radiative transfer and also determine whether aerosol particles have a net warming or cooling effect on climate. This effect described by three related optical properties of aerosols. Aerosols play a crucial role in Earth's atmosphere, influencing climate, weather patterns, and air quality. These tiny particulate matter, which can be of natural or anthropogenic origin, act as cloud condensation nuclei, facilitating cloud formation and impacting precipitation processes.
