This book was released on 1992-02-01 with total page 525 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite more than 20 years of regulatory efforts, concern is widespread that ozone pollution in the lower atmosphere, or troposphere, threatens the health of humans, animals, and vegetation. This book discusses how scientific information can be used to develop more effective regulations to control ozone. Rethinking the Ozone Problem in Urban and Regional Air Pollution discusses: The latest data and analysis on how tropospheric ozone is formed. How well our measurement techniques are functioning. Deficiencies in efforts to date to control the problem. Approaches to reducing ozone precursor emissions that hold the most promise. What additional research is needed. With a wealth of technical information, the book discusses atmospheric chemistry, the role of oxides of nitrogen (NOx) and volatile organic compounds (VOCs) in ozone formation, monitoring and modeling the formation and transport processes, and the potential contribution of alternative fuels to solving the tropospheric ozone problem. The committee discusses criteria for designing more effective ozone control efforts. Because of its direct bearing on decisions to be made under the Clean Air Act, this book should be of great interest to environmental advocates, industry, and the regulatory community as well as scientists, faculty, and students.
Download or read book Atmospheric Ozone as a Climate Gas written by Wei-Chyung Wang and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the major findings in the 1992 IPCC report and the 1994 World Meteorological Organization's Ozone Assessment report was the identification of possible climatic effects over the last few decades resulting from anthropogenic ally-induced changes in atmospheric ozone. The initial quantitative estimates of their direct climatic effects indicate significant impacts, though large uncertainties exist and studies using general circulation models are needed. A point that needs to be addressed in particular is that atmospheric ozone differs from greenhouse gases in that it is formed and destroyed by chemical processes in the atmosphere due to interaction involving a large number of source gases (e. g. H0, NO ' CO, 2 x NMHC, N0, CH and the CFCs). Therefore, the indirect effect of climate-chemistry 2 4 interaction involving atmospheric ozone is an important aspect for consideration in general circulation models. During the last few years, there have been several international workshops related to atmospheric ozone. In 1987, a NATO workshop on atmospheric ozone was held in Lillehammer, Norway. More recently, two workshops were organized to discuss the topic "General Circulation Model Study of Climate-Chemistry Interaction. " The first was held August 19-21, 1992, in Oslo, Norway, and the second held May 26-27,1993, in Albany, New York, USA. The two workshops were IAMAP activities under the Trace Constituent Working Group.

This book was released on 2007-04-25 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research of the last decade has demonstrated that ecosystems and human systems are influenced by multiple factors, including climate, land use, and the by-products of resource use. Understanding the net impact of a suite of simultaneously occurring environmental changes is essential for developing effective response strategies. Using case studies on drought and a wide range of atmosphere-ecosystem interactions, a workshop was held in September 2005 to gather different perspectives on multiple stress scenarios. The overarching lesson of the workshop is that society will require new and improved strategies for coping with multiple stresses and their impacts on natural socioeconomic systems. Improved communication among stakeholders; increased observations (especially at regional scales); improved model and information systems; and increased infrastructure to provide better environmental monitoring, vulnerability assessment, and response analysis are all important parts of moving toward better understanding of and response to situations involving multiple stresses. During the workshop, seven near-term opportunities for research and infrastructure that could help advance understanding of multiple stresses were also identified.
Download or read book New Theories And Predictions On The Ozone Hole And Climate Change written by Qing-bin Lu and published by World Scientific. This book was released on 2015-06-11 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph reviews the establishment of new theories of the ozone hole and global climate change, two major scientific problems of global concern. It provides a comprehensive overview of the author's work including significant discoveries and pioneering contributions, such as the discovery of extremely effective dissociative electron transfer reactions of chlorofluorocarbons (CFCs) adsorbed on ice surfaces and its implications for atmospheric ozone depletion; the proposal of the cosmic-ray-driven electron-induced-reaction (CRE) theory for the ozone hole; the predictions of 11-year cyclic variations in polar ozone loss and stratospheric cooling; the discovery of the nearly perfect linear correlation between CFCs and global surface temperature; the proposal of the CFC theory for modern global warming; the discovery of greenhouse-gas-specific climate sensitivity and the parameter-free calculation of global surface temperature change caused by CFCs; the prediction of global cooling; and so on.Unlike conventional atmospheric and climate models, the author's theoretical models were established on robust observed data rather than computer simulations with multiple parameters. The new theories have shown the best agreements with the observed data within 10% uncertainties. This book highlights the scientific understandings of the world-concerned problems from the unique point of view of a physicist who seeks theories with great simplicity and superior predictive capacity.This book is self-contained and unified in presentation. It may be used as an advanced book by graduate students and even ambitious undergraduates in physics, chemistry, environmental and climate sciences. It is also suitable for non-expert readers and policy makers who wish to have an overview of the sciences behind atmospheric ozone depletion and global climate change.
Download or read book Climate Change and Stratospheric Ozone Depletion written by Sari Kovats and published by WHO Regional Office Europe. This book was released on 2000-11 with total page 127 pages. Available in PDF, EPUB and Kindle. Book excerpt: A balanced assessment based on currently available scientific knowledge of the effects that climate change may have on the environment in Europe and the health of its populations. Written in non-technical language the book responds to growing public and political concern about the consequences of such widely publicized phenomena as global warming and stratospheric ozone depletion. The book also responds to evidence that recent warming trends in Europe have already affected health. The book opens with a brief explanation of the causes of climate change and stratospheric ozone depletion followed by an overview of recent European and global initiatives aimed at monitoring trends and assessing their impact on health. The first main chapter on climate change in Europe summarizes currently documented trends and provides a scenario of possible changes throughout the rest of this century. The second and most extensive chapter reviews scientific evidence on specific health consequences. These include effects related to increased episodes of thermal stress and air pollution; changes in foodborne water-related vector-borne and rodent-borne diseases; mortality from floods and other weather extremes; and changes in the production of aeroallergens associated with respiratory disorders including asthma. Chapter three considers health effects linked to stratospheric ozone depletion giving particular attention to adverse effects on the eye and immune system and skin cancer. The remaining chapters discuss health effects expected in the next decade and outline actions urgently needed in the areas of policy monitoring and surveillance and research.
Download or read book Atmospheric Ozone Dynamics written by Costas Varotsos and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: An increasing allllo~/allce because of the anthropogenically induced ozone depletion and relevant illcrca5e of the surface ultraviolet (UV) radiation (including erythemal part of the UV spectrum) has resulted in the growth of interest to total ozone (TOZ) surface and satellite observations, surface UV measurements (with an emphasis on UV -B) and. the interpretation of observation results to assess potential impacts of the UV radiation enhancement on man and biosphere. The significance of this phenomenon is diJIcrent in various cowltries. Special attention has been paid, for instance, to ozone depletion and UV radiation increase at high latitudes (this problem has also been discussed during the Workshop). It is equally clear, however, that low and mid-latitude environmental dynamics requires carefuU monitoring and assessment of environm(:ntal trends as well. Such a conclusion is especially true for the Mediterranean Region where numerous resort places are located and subject to excessive levels of Solar Ultraviolet Radiation. This is why the NATO Advanced Rcsearch Workshop "Ground-Level and Satellite Ozone Observations: Changes in the Mediterranean Region" was organized and took place in Athens (Grcccc) during the Lime period 31 October -4 November 1995. It should be pointed out, however, that presentations discussed during the Workshop went far beyond the regional scale of consideration. This has been very important, because it opened an opportwlity to analyse the Mediterrane:an environmental situation in the broader contcx1 of the European global changes.
Download or read book Remote Sensing and Atmospheric Ozone written by Arthur Philip Cracknell and published by Springer Science & Business Media. This book was released on 2012-06-21 with total page 701 pages. Available in PDF, EPUB and Kindle. Book excerpt: The destruction of the ozone layer, together with global warming, is one of the hot environmental topics of today. This book examines the effect of human activities on atmospheric ozone, namely the increase of tropospheric ozone and the general diminution of stratospheric ozone and the production of the Antarctic ozone hole. Also discussed is the role of remote sensing techniques in the understanding of the effects of human activities on atmospheric ozone as well as in the development of social and political awareness of the damage to the ozone layer by man-made chemicals, principally CFCs. This led to the formulation and ratification in 1989 of the Montreal Protocol on controlling/banning the manufacture and use of chemicals that damage the ozone layer. Since then, remote sensing has played a key role in monitoring atmospheric ozone concentration and determining the success of the Montreal Protocol in protecting the ozone layer from further damage. In this book, the renowned authors discuss the sophisticated instruments that have been launched into space to study not only ozone but also other trace gases in the atmosphere, some of which play a key role in the generation and destruction of ozone in the atmosphere. Professors Cracknell and Varotsos also examine the satellite-flown instruments which are involved in monitoring the absorption of solar ultraviolet light in the atmosphere in relation both to the generation and destruction of ozone and consequently to human health. This scholarly book, written by the foremost experts in the field, looks at remote sensing and its employment in the various aspects of ozone science. It is widely acknowledged that global warming, due to anthropogenic greenhouse gases emissions, represents a threat to the sustainability of human life on Earth. However, many other threats are potentially just as serious, including atmospheric pollution, ozone depletion, water pollution, the degradation of agricultural land, deforestation, the depletion of the world's mineral resources and population growth.

Download or read book Tropospheric Ozone written by Ivar S.A. Isaksen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main objective of the workshop was to increase our knowledge of ozone formation and distribution in the troposphere, its relation to precursor (NO~ and HC species) distribution, how it is affected by transport processes in the troposphere, and to show how the increasing levels of ozone can cause environmental problem. The focus was on the interaction of ozone on regional and global scales. There is mounting evidence that such interactions occur and that the ozone levels are increasing in most of the Northern Hemisphere tropo sphere. A likely source of ozone increase is human activity. As result of this, tropospheric climate may change significantly within a few decades, either through direct effects by ozone itself or indirectly through its effect on other radiatively active trace species. Further more, ozone may have adverse effects on vegetation over large continental areas due to enhanced levels which have been measured to take place. As it is well known that ozone plays a key role in the oxidation of a large number of chemical species in the troposphere, natural as well as man-made, the atmospheric distribution of important trace species like sulfur dioxide, nitrogen oxides and hydrocarbons could be markedly changed as a result of ozone changes. The rapidly increasing interest in tropospheric ozone, and the key role ozone plays in several atmospheric areas as well the obvious increase in the tropospheric concentration of ozone made ozone a natural choice as a topic for the workshop.
Download or read book Fourth Dimension in Building written by National Research Council and published by National Academies Press. This book was released on 1993-02-01 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: Public facilities are valuable assets that can provide decades of high quality of service if they are effectively utilized. Despite effective planning, design, and management, sometimes users or owners change and have requirements different from those that the facility was initially intended to fulfill. In addition, the technologies sometimes change, making facilities obsolete before they have worn out or otherwise failed. This book explores the meaning of obsolescence as the term applies to buildings. It discusses the functional, economic, technological, social, legal, political, and cultural factors that can influence when obsolescence will occur and considers what design professional and building owners and users can do to delay and minimize the costs of obsolescence. The analyses apply to all buildings, but public facilities are given added attention because of their special management problems.

This book was released on 2013-06-29 with total page 367 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inadvertent alterations of the earth's atmosphere by man's activities are now of regional and even global proportion. Increasing concern has been focused in the last decade on consequences of acid rain, carbon dioxide enrichment of the atmosphere and reduction of ozone in the upper atmosphere. The latter two problems are of truly global scale. This book focuses on the atmospheric ozone reduction problem and the potential consequences for plant life. unlike carbon dioxide enrichment, reduction of the total atmospheric ozone column has not yet taken place to a noticeable degree -- it is a problem of the future. The processes leading to ozone reduction involve time periods on the scale of decades. However, by the same token, if society finds ozone reduction to be unacceptable it will take even longer for the process to be reversed. Thus, anticipation of the consequences of ozone reduction is of obvious importance. Speculation of the possibility of ozone reduction first appeared in the early 1970's and was focused on the consequences of the injection of large quantities of nitrogen oxides into the upper atmosphere by supersonic aircraft flying at high altitudes. Other sources of nitrogen oxides originating from the earth's surface were also considered. With further refinement, the concerns of nitrogen oxide pollution of the upper atmosphere were diminished since the quantities likely to be involved were insufficient to cause a serious threat to the ozone layer.
