Earth Sciences Division Research at GISS Atmospheric Chemistry Atmospheric chemistry is the study of the chemical constituents of Earth's atmosphere, and the roles they play in influencing the atmosphere's temperature, radiation, and dynamics. Changes in the composition of the atmosphere can affect the habitability of the planet, for example, by altering long-term climate, depleting the ozone layer, or affecting air quality at the ground. Research in this field is therefore concerned with biogenic and anthropogenic emissions, trace gas distributions, and the chemical reactions of molecules and atoms in the atmosphere. Research in atmospheric chemistry at GISS includes near-term issues such as air quality and ozone depletion but is primarily focused on the longer-term linkages between atmospheric chemistry and global climate. Changes in the emission of chemical species naturally present in the atmosphere, such as the greenhouse gases carbon dioxide (CO ), methane (CH

ATMOSPHERIC CHEMISTRY G.A. Blake Group California Institute of Technology Overview For example, stable isotopes have long served as an invaluable tool in geochemical studies of the solid and liquid reservoirs of the earth. As outlined more fully below, stable isotopes also have the potential to provide critical new insights into a variety of issues in atmospheric science, yet have been only rarely pursued. In part this arises because the measurements are difficult, requiring precisions and accuracies in the part per ten thousand range, but also because the science that can be pursued with stable isotopic studies of atmospheric trace gases is only now becoming clear. We have begun a new laboratory program that utilizes stable isotopes to examine the fate of important biogenic trace gases such as nitrous oxide, and are developing new in situ measurement approaches for such species using infrared laser induced fluorescence. With Paul Wennberg's group we are also beginning a new effort in Br/BrO detection in the vacuum ultraviolet, as described below. Stables Isotopes and Nitrous Oxide Photolysis Nitrous oxide exists in the Earth's atmosphere at a current concentration of approximately 310 ppbv and is increasing at an annual rate of about 0.25-0.31%. Despite being present in only trace amounts, nitrous oxide exerts a large influence on the terrestrial climate in two major ways: (1) It is one of the main greenhouse gases because of its long atmospheric lifetime (~100-150 years) and its large radiative forcing capabilities (nearly 200 times that of carbon dioxide), and (2) It is the principal source of NO

Our understanding of processes such as air pollution, stratospheric ozone depletion, global biogeochemical cycles, and global climate change is limited by the available observational data and by the number of trained investigators in this area. At the University of Maryland our research has focused on building the data base, using these data to improve numerical simulations, using computer model output to identify definitive measurements - through a balance of experiment and theory we can better understand the atmosphere.

Next Atmospheric Chemistry: New Insights Define Current Research When one reviews the knowledge of atmospheric chemical composition as it existed two or three decades ago, one is struck by the primitive state of the science It is now understood that the atmosphere is a reactive environment. National Academy of Sciences, 1984 In spite of the relatively primitive state of the science of atmospheric chemistry in the late 1950s, the authors of the UCAR "Blue Book" proposed chemistry as one of the disciplines that should be included in a broad and vigorous attack on scientific problems of the atmosphere. They recognized that some chemical species in the atmosphere are far from inert and suggested some scientific issues that the new institute should address: For example, the photochemical processes by which the ionization and recombination of gaseous components is [sic] achieved are only partly known. The chemical equilibrium of ozone in the upper atmosphere has a profound influence on biological processes on the ground as well as being a possible link between fluctuations in the emission of ultra- violet energy from the sun and atmospheric motion at lower levels. The distribution and decay of natural and artificial radioisotopes, the carbon dioxide and nitrogen cycles in the atmosphere, and the processes by which particulate materials are diffused and removed from the atmosphere are problems which have assumed ecological significance.

Applied Sciences Atmospheric Chemistry Biomass Burning Recent information suggests that on the global scale, biomass burning is much more extensive and widespread than previously thought. Biomass burning refers to the burning of the world's forests and grasslands and agricultural lands following the harvest for land clearing and land conversion. Biomass burning is a global phenomenon occurring in the tropics (tropical rain forests and savanna grasslands), in the temperate zone and in the boreal forest. GTE - Global Tropospheric Experiment GTE utilizes large, extensively instrumented aircraft as primary research tools. However, GTE also draws heavily upon satellite observations of meteorology, land use and atmospheric chemical species to aid in experiment design and in the scientific analyses of results obtained from aircraft and ground-based measurements. The GTE, managed through the Tropospheric Chemistry Program in the Earth Science Division, Science Mission Directorate at NASA Headquarters, was initiated in the early 1980s. Implementation of the GTE Project is the responsibility of the Science Directorate at the NASA Langley Research Center. IMPACT - Interactive Modeling Project for Atmospheric Chemistry and Transport Atmospheric modeling and simulation studies have been invaluable in the development of our current level of understanding of the fundamental processes of radiation, chemistry and dynamics that ultimately determine the circulation, thermal structure and distribution of constituents in the Earth's atmosphere. Many of these studies have treated the processes independently or have suppressed important couplings between them. This approach was a conscious strategy adopted to make the studies tractable and often relied on assumptions that the couplings were weak enough to neglect. Recently however, there has been increased awareness that many phenomena of interest may involve subtle and complex interactions among these processes.
