"Atmospheric chemistry is a branch of atmospheric science in which the chemistry of the Earth's atmosphere and that of other planets is studied."
The study of the chemical composition and reactions in the Earth's atmosphere, including air pollution and climate change.
Composition of the Atmosphere: Understanding the fundamental constituents of the Earth's atmosphere, including gases, liquids and aerosols.
Climate Change: The impact of climate change on the environment, including the increase in greenhouse gases and their role in global warming.
Air Pollution: The sources and effects of air pollution, including harmful gases and particles from transportation, factories, and other man-made sources.
Ozone Depletion: How the ozone layer in the Earth's stratosphere is being depleted by human activities, such as the use of chlorofluorocarbons (CFCs).
Acid Rain: The causes and effects of acid rain, which is caused by the release of sulfur dioxide and nitrogen oxides into the atmosphere.
Particulate Matter: Small particles in the air that can have adverse health effects, including respiratory problems.
Air Quality Monitoring: The measurement and analysis of air quality, including the use of sensors, satellites, and other technology.
Stratospheric Chemistry: The chemistry of the Earth's stratosphere, including the ozone layer, ultraviolet radiation, and other important atmospheric processes.
Tropospheric Chemistry: The chemistry of the Earth's troposphere, including the formation and transformation of pollutants and other chemical reactions.
Atmospheric Modeling: The use of computer models and simulations to understand atmospheric processes and predict future trends.
"It is a multidisciplinary approach of research and draws on environmental chemistry, physics, meteorology, computer modeling, oceanography, geology and volcanology, and other disciplines."
"Research is increasingly connected with other areas of study such as climatology."
"The composition and chemistry of the Earth's atmosphere is of importance for several reasons, but primarily because of the interactions between the atmosphere and living organisms."
"The composition of the Earth's atmosphere changes as a result of natural processes such as volcano emissions, lightning, and bombardment by solar particles from the corona."
"It has also been changed by human activity and some of these changes are harmful to human health, crops, and ecosystems."
"Examples of problems which have been addressed by atmospheric chemistry include acid rain, ozone depletion, photochemical smog, greenhouse gases, and global warming."
"Atmospheric chemists seek to understand the causes of these problems."
"...obtaining a theoretical understanding of them allows possible solutions to be tested and the effects of changes in government policy evaluated."
