Product Description
The ozone gas layer in the upper atmosphere is essential for life on earth because it prevents harmful ultraviolet rays from reaching the ground. On Earth, however, ozone can be harmful to living things. The debate over ozone's dual nature is explored as scientists, policy makers, and the public confront ozone smog on earth and the ozone hole in the upper atmosphere. ... Read more

Product Description
These proceedings describe the current state-of-the-art of ozone research. A wide range of topics is discussed including: emissions, transport and transformation of precursors of ozone and of ozone itself, the distribution of ozone, the deposition of ozone at the earth's surface, and its effects on man and the environment. Attention is also given to the role of stratospheric ozone and the role of the ultraviolet radiation which is transmitted through the ozone layer. Finally it describes in detail present and future policy measures to reduce the ozone in the lower atmosphere and to protect the ozone layer in the stratosphere. Many of the papers describe recent developments and new research results. Research carried out in both in Europe and in the United States is described, as are the policy measures which are being taken by both European and U.S. governments. ... Read more

Description:
A simulation with the climate-chemistry model (CCM) E39/C is presented, which covers both the troposphere and stratosphere dynamics and chemistry during the period 1960 to 1999. Although the CCM, by its nature, is not exactly representing observed day-by-day meteorology, there is an overall model's tendency to correctly reproduce the variability pattern due to an inclusion of realistic external forcings, like observed sea surface temperatures (e.g. El Nino), major volcanic eruption, solar cycle, concentrations of greenhouse gases, and Quasi-Biennial Oscillation. Additionally, climate-chemistry interactions are included, like the impact of ozone, methane, and other species on radiation and dynamics, and the impact of dynamics on emissions (lightning). However, a number of important feedbacks are not yet included (e.g. feedbacks related to biogenic emissions and emissions due to biomass burning). The results show a good representation of the evolution of the stratospheric ozone layer, including the ozone hole, which plays an important role for the simulation of natural variability of tropospheric ozone. Anthropogenic NO"x emissions are included with a step-wise linear trend for each sector, but no interannual variability is included. The application of a number of diagnostics (e.g. marked ozone tracers) allows the separation of the impact of various processes/emissions on tropospheric ozone and shows that the simulated Northern Hemisphere tropospheric ozone budget is not only dominated by nitrogen oxide emissions and other ozone pre-cursors, but also by changes of the stratospheric ozone budget and its flux into the troposphere, which tends to reduce the simulated positive trend in tropospheric ozone due to emissions from industry and traffic during the late 80s and early 90s. For tropical regions the variability in ozone is dominated by variability in lightning (related to ENSO) and stratosphere-troposphere exchange (related to Northern Hemisphere Stratospheric dynamics and solar activity). Since tropospheric background chemistry is regarded only, the results are quantitatively limited with respect to derived trends. However, the main results are regarded to be robust. Although the horizontal resolution is rather coarse in comparison to regional models, such kind of simulations provide useful and necessary information on the impact of large-scale processes and inter-annual/decadal variations on regional air quality. ...

Product Description
Tropospheric ozone has long been recognized as a major environmental concern. Levels of ozone concentration have grown dramatically and the effects of ozone exposure have been examined in virtually thousands of studies worldwide. This timely new reference presents the state of the art in ozone regulation, human health effects, agricultural implications, and the economics of ozone reduction. Tropospheric Ozone guides you through the history of air pollution legislation and cites government initiatives to reduce ozone emissions. Ozone concentration data is supplied for a variety of geographic regions in examining the causes of ozone concentration and its potential effects on human populations, crops, and forests. Important issues such as crop yield, plant growth, and crop losses due to exposure are addressed, which will help develop an understanding of the economic implications of agricultural damage. New information is presented regarding risk assessment and human monitoring studies. EPA guidelines are reviewed, and potential health problems associated with ozone exposure are discussed in a practical, informative format. This valuable reference will benefit air pollution engineers, environmental consultants, government agency employees, regulators, industry professionals, health professionals, crop and soil scientists, environmental health and safety professionals, risk assessment professionals, and students in the environmental sciences. ...

Product Description
The book contains information on geology, climate and vegetation of the Sierra Nevada with a special emphasis on air pollution effects on the mixed conifer forests.

A history of the extent of air pollution effects on mixed conifer forests, especially ponderosa and Jeffrey pines is provided. The physiological basis for ozone-type injury development in ponderosa pine, a discussion of ozone uptake by plants at different levels of biological organization and the effects of air pollution and other stresses on mountain forests are discussed. A considerable portion of the book is dedicated to development of statistical models and maps of ambient ozone distribution in the Sierra Nevada based on the 1999 monitoring data with passive samplers. The implications of the methodological results, formulation and application of regional air quality models for integrated assessment of urban and wildland pollution and the need for functionally integrated models of ozone deposition to the Sierra Nevada forests are also discussed. Management and monitoring needs for improved long-term understanding air pollution effects on forest ecosystems, discussion of options for proper management of the air pollution affected forests, and comparison of monitoring and modelling of ozone and forest health status in the Sierra Nevada with similar efforts in mountains of North American and European mountain ranges are the focus of the later chapters of the book.

It has many industrial and consumer applications. This new book presents the latest research in the field from around the globe. ... Read more

Product Description
This long-awaited two-volume book examines how the interplay of ideas and actions applied to environmental problems has laid the foundations for global environmental management. It looks at how ideas, interests, and institutions affect management practice; how management capabilities in other areas affect the ability to deal with specific environmental issues; and how learning affects society's approach to the global environment.

The book focuses on efforts to deal with climate change, ozone depletion, and acid rain from 1957 (The International Geophysical Year) through 1992 (the UN Conference on Environment and Development). The settings include Canada, Germany, Hungary, Japan, Mexico, the Netherlands, the former Soviet Union, the United Kingdom, the United States, and international environmental organizations. Topics include problem framing, agenda setting, issue attention, risk assessment, monitoring, option assessment, goal and strategy formulation, implementation, and evaluation. Volume 1 provides an overview of the project, of global environmental management in general, and of the three central environmental issues studied; it also contains the individual country studies. Volume 2 contains the management function studies and the book's conclusion.

Authors in the set include: Jeannine Cavender-Bares, William C. Clark, Ellis Cowling, Nancy M. Dickson, Gerda Dinkelman, Rodney Dobell, Renate Ell, Adam Fenech, Alexander Ginzburg, Elena Goncharova, Peter Haas, Eva Hizsnyik, Michael Huber, Peter Hughes, Jill Jäger, Marc Levy, Angela Liberatore, Diana Liverman, Justin Longo, David McCabe, Donald Munton, Elena Nikitina, Karen O'Brien, Edward Parson, Vladimir Pisarev, Ruud Pleune, Miranda Schreurs, Simon Shackley, Peter Simmons, Heather Smith, Vassily Sokolov, Ferenc L.
