What is Atmospheric Chemistry?
Atmospheric Chemistry is the study of the composition of the atmosphere, the sources and fates of gases and particles in air, and changes induced by natural and anthropogenic processes. Although a relatively new field, it has received growing attention since many of the environmental problems of greatest importance involve trace vapors and aerosols. Popular examples are the ozone hole, greenhouse gases and urban air pollution.
Atmospheric Chemistry has as its foundation the photochemistry of the molecular constituents of air. However, atmospheric chemists also study the formation and properties of airborne particles, cloud processing of materials, transport and dispersion of chemical tracers, and biogeochemical cycles. In practice, these activities translate into the development of instruments and models for studying the atmosphere, and the application of such tools to answer scientific questions. The atmosphere most easily reveals its secrets to those who are willing to think broadly. Atmospheric chemistry is a truly multidisciplinary field that seeks understanding of the environment through broad thinking.
