Available in PDF, EPUB and Kindle. Book excerpt: Fine particulate (PM2.5) continues to be a major air pollution problem due to its adverse effects on human health and the environment. Recently, the rapid industrialization now taking place in Asia is producing a large and growing quantity of NOX, SO2, CO and other atmospheric emissions. This research is part of the work of project "Intercontinental Transport and Climatic Effects of Air Pollutants" (ICAP) sponsored by U.S. Environment Protection Agency (EPA). It presents modeling and interpretation of the impact of Asian anthropogenic emissions on air quality in the U.S. through long distance transport of Asian air pollutants. In order to better quantify the magnitude and impacts of Asia anthropogenic emission on U.S. air quality caused by intercontinental transport, a 3-D regional air quality model, the EPA Models-3 Community Multiscale Air Quality (CMAQ) system has been employed in this study. The model is applied to both baseline simulation of 2001 and the sensitivity simulation in which anthropogenic Asian emissions were turned off. The baseline simulation was evaluated with both surface data over U.S. and aircraft observation over Western Pacific regions. Compared to surface measurement over U.S., over 50% of the simulated PM2.5 concentrations fall within a factor of two of the observations in all seasons except winter. Model evaluation using vertical aircraft data indicates that the model is able to well reproduce the vertical distributions of SO42-, NO3-, NH4+ and CO. Concentrations of all species decrease rapidly with increasing altitude below 6 km, followed by a much slower decrease between 6 and 12 km. Time series analysis indicates that model can place the plume in the right location, but tends to under-predict the peak values of the plume intensity. This study shows that the impact of Asian man-made emissions is persistent throughout the entire year rather than episodic. There also exists a significant seasonal cycle with an April/May maximum (1~1.2 _.

This book was released on 2004-07-12 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transboundary transport of air pollution has been a topic of scientific research for several decades and has also been addressed already by environmental policies. However, the importance of air pollution transport on the largest - intercontinental - scales, has been recognized only recently. It was soon found that the meteorological and chemical processes involved in intercontinental pollution transport are distinctly different from those occurring during regional-scale transport, and thus new scientific methodologies are required for their study. In this book, leading scientists review the current state of knowledge in this emerging field of research, providing the reader with a process understanding of global-scale transport and its influence on the atmosphere's chemical composition. Long-range transport of anthropogenic pollution is contrasted with that of pollution produced by natural processes such as dust storms or forest fires. Furthermore, the prospects for international management of intercontinental transport of anthropogenic pollution are discussed.

Download or read book Exchange and Transport of Air Pollutants over Complex Terrain and the Sea written by Soren E. Larsen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the regional models required to understand and control the generation, distribution and deposition of air pollutants become more precise, the need to understand the detailed effects of hilly and mountainous terrain becomes more acute. The Alpine regions and the mountainous Mediterranean coasts have large effets on the way the pollutant burden is spread in their areas. Similarly an understanding of the effects of chemical and physical processes controlling pollutant deposition and the emission of biogenic compounds is essential to the correct modelling of the coastal regions which surround so much of Europe. The results from two projects on these problems are presented in this volume: one involved a series of field campaigns in the Alps and in the Rhine valley, the other involves ships and platforms in the North Sea and also in the Mediterranean.
Download or read book Global Sources of Local Pollution written by National Research Council and published by National Academies Press. This book was released on 2010-02-15 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent advances in air pollution monitoring and modeling capabilities have made it possible to show that air pollution can be transported long distances and that adverse impacts of emitted pollutants cannot be confined to one country or even one continent. Pollutants from traffic, cooking stoves, and factories emitted half a world away can make the air we inhale today more hazardous for our health. The relative importance of this "imported" pollution is likely to increase, as emissions in developing countries grow, and air quality standards in industrial countries are tightened. Global Sources of Local Pollution examines the impact of the long-range transport of four key air pollutants (ozone, particulate matter, mercury, and persistent organic pollutants) on air quality and pollutant deposition in the United States. It also explores the environmental impacts of U.S. emissions on other parts of the world. The book recommends that the United States work with the international community to develop an integrated system for determining pollution sources and impacts and to design effective response strategies. This book will be useful to international, federal, state, and local policy makers responsible for understanding and managing air pollution and its impacts on human health and well-being.

Book excerpt: This discussion deals with a family of air quality models for predicting and analyzing the fine particulate loading in the atmosphere, for assessing the extent and degree of visibility impairment, and for determining the potential of pollutants for increasing the acidity of soils and water. The major horizontal scales of interest are from 400km to 2000km; and the time scales may vary from several hours, to days, weeks, and a few months or years, depending on the EPA regulations being addressed. First the role air quality models play in the general family of atmospheric simulation models is described. Then, the characteristics of a well-designed, comprehensive air quality model are discussed. Following this, the specific objectives of this workshop are outlined, and their modeling implications are summarized. There are significant modeling differences produced by the choice of the coordinate system, whether it be the fixed Eulerian system, the moving Lagrangian system, or some hybrid of the two. These three systems are briefly discussed, and a list of hybrid models that are currently in use are given. Finally, the PNL regional transport model is outlined and a number of research needs are listed.

This book was released on 2000 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main objective of this study was to investigate the effect of the addition of new stretches of freeways (Loop 101 and 51) in the north Phoenix Valley. The strengths and locations of pollution "Hot Spots" in this area have been found to be related to the meteorological conditions. Based on the model results, the new freeway extensions would increase the pollutant concentration (i.e., CO) in the surrounding area. Different scenarios have been used to simulate the pollutant dispersion over the Valley by using the CAL3QHC model.

Download or read book Hemispheric Transport of Air Pollution HTAP written by and published by . This book was released on 2016 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 2012, the Hemispheric Transport of Air Pollution (HTAP) Task Force launched a cooperative multi-model experiments and analysis (HTAP Phase 2) that is intended to inform the Convention on Long-range Transboundary Air Pollution (LRTAP) and other multi-lateral cooperative efforts, as well as national governments on actions to decrease air pollution and its impacts. The HTAP Phase 2 modelling experiments have been designed to provide: - relative contributions of regional and extra-regional sources of air pollution in different regions of the world that will help refine the source/receptor relationships derived from the previous HTAP Phase 1 simulations. - a basis for model evaluation and process studies to characterize the uncertainty in the estimates of regional and extra-regional contributions and to understand the differences between models. - input to assessments of the impacts of control strategies on the contribution of regional and extra-regional emissions sources to the exceedance of air quality standards and to impacts on human health, ecosystems, and climate. The purpose of this report is to gather in a single document the guidance and technical specifications provided from 2012 to end of 2015 by the Joint Research Center (European Commission) to the global modelers participating to HTAP Phase 2, which are currently only partly accessible through the HTAP WIKI pages (Annex 1). It also includes some information on the input to the AQMEII (Air Quality Model Evaluation International Initiative) and MICS (Model Inter-comparison Study for Asia) regional simulations performed in the frame of HTAP2, as well as additional information with respect to the HTAP_v2.2 global emission inventory. This report provides detailed background information to a technical overview paper (Galmarini et al., 2016) in the special issue of the Atmospheric Chemistry and Physics journal, entitled 'Global and regional assessment of intercontinental transport of air pollution: results from HTAP, AQMEII and MICS.
