The Role Of Atmospheric Chemistry In Shaping Air Quality And Climate Change

Abstract

Atmospheric chemistry plays a pivotal role in regulating air quality and driving climate change processes. The interactions between chemical species in the atmosphere—such as ozone, volatile organic compounds, nitrogen oxides, and aerosols—profoundly influence the composition, radiative balance, and oxidative capacity of the atmosphere. These chemical transformations affect both short-lived climate forcers and long-lived greenhouse gases, altering regional and global temperature patterns and contributing to extreme weather events. Human activities, particularly fossil fuel combustion, industrial processes, and land use changes, have significantly altered atmospheric chemical pathways, leading to increased concentrations of pollutants and greenhouse gases. Additionally, the feedback mechanisms between atmospheric chemistry and meteorological variables further complicate the prediction of climate and air quality outcomes. Understanding these interactions is essential for developing effective mitigation and adaptation strategies. This paper reviews the key processes of atmospheric chemistry, highlights their implications for air pollution and climate dynamics, and explores emerging research tools, including satellite remote sensing and advanced modeling, which provide deeper insights into atmospheric transformations. Emphasis is placed on the need for integrated policy frameworks that consider both air quality and climate goals in light of atmospheric chemistry
