The atmospheric effect refers to the physical, chemical, and biological processes that occur within the Earth’s atmosphere and influence environmental conditions as well as human health. The atmosphere is a complex and dynamic system composed of gases such as nitrogen, oxygen, carbon dioxide, water vapor, and trace elements. These components interact continuously under the influence of solar radiation, gravity, and terrestrial processes, leading to various atmospheric phenomena. Atmospheric effects include temperature regulation, weather formation, air pollution, and chemical transformations that affect ecosystems and living organisms. One of the most significant atmospheric effects is the regulation of Earth’s temperature through the greenhouse effect. Certain gases in the atmosphere, such as carbon dioxide, methane, and water vapor, trap heat radiated from the Earth’s surface, preventing it from escaping into space. This process maintains a stable temperature suitable for life. However, excessive accumulation of these gases due to human activities like burning fossil fuels and deforestation enhances the greenhouse effect, leading to global warming and climate change. These changes alter weather patterns, increase the frequency of extreme events, and have direct and indirect impacts on environmental health. Another important atmospheric effect is the scattering and absorption of solar radiation. When sunlight enters the atmosphere, it interacts with gas molecules and particulate matter. Shorter wavelengths of light are scattered more effectively, giving the sky its blue color. At the same time, certain gases such as ozone absorb harmful ultraviolet radiation, protecting living organisms from its damaging effects. The depletion of the ozone layer
