Research is increasingly connected with other areas of study such as climatology The composition and chemistry of the 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 has 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 and global warming . Atmospheric chemistry seeks to understand the causes of these problems, and by obtaining a theoretical understanding of them, allow possible solutions to be tested and the effects of changes in government policy evaluated.

13. Atmospheric Chemistry Glossary Words and phrases used in atmospheric chemistry and environmental studies http://www.shsu.edu/~chemistry/Glossary/glos.html

Atmospheric Chemistry Glossary 2010 Version This is the 2010 version of this glossary. The definitions in this glossary were initially generated by the students in a senior-level class studying air quality and atmospheric chemistry at Sam Houston State University during the spring of 1995 in a course entitled Environmental Science 440/Chemistry 442, AIR QUALITY. In the main, they wrote these definitions as part of a class requirement. They are updated almost every year. The references found at the end of most entries are an effort to supply additional resources for each of the terms. No supposition of comprehensiveness or absolute correctness can be assumed in any way. Many of the glossary entries have hypertext links to other sites on the Internet. These external links were valid in the spring of 2010. The 2010 version was created in the fifteenth year for this project and is dedicated to the SHSU Air Quality students who are its authors.

Security and Privacy Notice PLEASE NOTE: Much of the science that had been planned for the Atmospheric Chemistry Program (ACP) will, in the future, be conducted under the Department of Energy's Atmospheric Science Program http://www.asp.bnl.gov . Beginning in Fiscal Year 2005, research will focus on radiative forcing of climate change by atmospheric aerosols. Please refer to the ASP web site for more information. The Atmospheric Chemistry Program (ACP) is a Global Change Research program sponsored by the Environmental Sciences Division of the U.S. Department of Energy (DOE) The overall objective of the ACP is to provide DOE with advanced information on the atmospheric environment that is required for long-range energy planning. The research is carried out primarily at four DOE laboratories and approximately twelve universities and non-DOE labs. The thrusts of this research are on regional and continental chemistry and fate of tropospheric air pollutants, extracontinental and global chemistry and fate of tropospheric air pollutants, and aerosol genesis. Laboratory studies emphasize rate and equilibrium processes. Field studies are conducted with aircraft and surface measurements on reaction chemistry, advective influences on the chemical composition of chemistry, and air-surface exchange processes. Modeling efforts address both chemistry and dynamics on regional and global scales.

Welcome to the Harvard Atmospheric Chemistry Modeling Group! Our goal is to understand the chemical composition of the atmosphere, its perturbation by human activity, and the implications for climate change and life on Earth. Our approaches include global modeling of atmospheric chemistry and climate, aircraft measurement campaigns, satellite data retrievals, and analyses of atmospheric observations.

Supplemental Problems for Introduction to Atmospheric Chemistry , 3rd edition (April 2010) Group News (updated October 22, 2010) November 2010: A new mechanistic global model of Hg biogeochemistry in the terrestrial environment The strong association of mercury (Hg) with organic carbon in terrestrial soils provides the framework for evaluating Hg cycling in the terrestrial environment. We developed a new global terrestrial mercury model (GTMM) that tracks the storage, accumulation and emissions of Hg in soils based on the cycling of the carbon pool that Hg is bound to. We find that most of the Hg in soils is bound to the most recalcitrant organic carbon pools, but that the fractional increase due to anthropogenic activity is concentrated in the most labile pools. This drives a 3-fold increase in Hg emissions to the atmosphere from the most labile pools relative to the pre-industrial period. Because anthropogenic Hg is preferentially located in more labile pools, the lifetime in soils is ~80 years, as opposed to a lifetime of ~600 years for natural Hg.
