Available in PDF, EPUB and Kindle. Book excerpt: The most serious problems to affect out atmospheric environment, such as urban air pollution, regional haze, acidic precipitation, and ozone depletion, occur over mesoscale travel distances and are consequently truly international in nature. In response to the increased awareness of these problems, many universities now offer interdisciplinary programmes in environmental science while many government and private organizations also support environmental projects. This study seeks to fulfil the need for a suitable text for graduate students working in the field. It consists of 13 chapters which review basic concepts, theories and modelling issues of pollutant dispersal in the atmosphere and related atmospheric systems affecting transport, transformation, and removal of air pollutants over mesoscale travel distances.

Download or read book Workbook of Atmospheric Dispersion Estimates written by D. Bruce Turner and published by CRC Press. This book was released on 2020-12-17 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: This completely updated and revised Second Edition of the popular Workbook of Atmospheric Dispersion Estimates provides an important foundation for understanding dispersion modeling as it is being practiced today. The book and accompanying diskette will help you determine the impacts of various sources of air pollution, including the effects of wind and turbulence, plume rise, and Gaussian dispersion and its limitations. Information is shown in summary graphs as well as in equations. The programs included on the diskette allow you to "get the feel" for the results you'll obtain through the input of various combinations of parameter values. The sensitivity of data to various parameters can be easily explored by changing one value and seeing the effect on the results. The book presents 37 example problems with solutions to show the estimation of atmospheric pollutant concentrations for many situations.
Download or read book Air Dispersion Modeling written by Alex De Visscher and published by John Wiley & Sons. This book was released on 2013-09-26 with total page 526 pages. Available in PDF, EPUB and Kindle. Book excerpt: A single reference to all aspects of contemporary air dispersion modeling The practice of air dispersion modeling has changed dramatically in recent years, in large part due to new EPA regulations. Current with the EPA's 40 CFR Part 51, this book serves as a complete reference to both the science and contemporary practice of air dispersion modeling. Throughout the book, author Alex De Visscher guides readers through complex calculations, equation by equation, helping them understand precisely how air dispersion models work, including such popular models as the EPA's AERMOD and CALPUFF. Air Dispersion Modeling begins with a primer that enables readers to quickly grasp basic principles by developing their own air dispersion model. Next, the book offers everything readers need to work with air dispersion models and accurately interpret their results, including: Full chapter dedicated to the meteorological basis of air dispersion Examples throughout the book illustrating how theory translates into practice Extensive discussions of Gaussian, Lagrangian, and Eulerian air dispersion modeling Detailed descriptions of the AERMOD and CALPUFF model formulations This book also includes access to a website with Microsoft Excel and MATLAB files that contain examples of air dispersion model calculations. Readers can work with these examples to perform their own calculations. With its comprehensive and up-to-date coverage, Air Dispersion Modeling is recommended for environmental engineers and meteorologists who need to perform and evaluate environmental impact assessments. The book's many examples and step-by-step instructions also make it ideal as a textbook for students in the fields of environmental engineering, meteorology, chemical engineering, and environmental sciences.

Download or read book A Real Time Atmospheric Dispersion Modeling System written by and published by . This book was released on 1999 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper describes a new 3-D multi-scale atmospheric dispersion modeling system and its on-going evaluation. This system is being developed for both real-time operational applications and detailed assessments of events involving atmospheric releases of hazardous material. It is part of a new, modernized Department of Energy (DOE) National Atmospheric Release Advisory Center (NARAC) emergency response computer system at Lawrence Livermore National Laboratory. This system contains coupled meteorological data assimilation and dispersion models, initial versions of which were described by Sugiyama and Chan (1998) and Leone et al. (1997). Section 2 describes the current versions of these models, emphasizing new features. This modeling system supports cases involving both simple and complex terrain, and multiple space and time scales from the microscale to mesoscale. Therefore, several levels of verification and evaluation are required. The meteorological data assimilation and interpolation algorithms have been previously evaluated by comparison to observational data (Sugiyama and Chan, 1998). The non-divergence adjustment algorithm was tested against potential flow solutions and wind tunnel data (Chan and Sugiyama, 1997). Initial dispersion model results for a field experiment case study were shown by Leone et al. (1997). A study in which an early, prototype version of the new modeling system was evaluated and compared to the current NARAC operational models showed that the new system provides improved results (Foster et al., 1999). In Section 3, we show example results from the current versions of the models, including verification using analytic solutions to the advection-diffusion equation as well as on-going evaluation using microscale and mesoscale dispersion field experiments.

Download or read book Application of an Advanced Atmospheric Mesoscale Model to Dispersion in the Rocky Flats Colorado Vicinity written by and published by . This book was released on 1993 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atmospheric Studies in Complex Terrain (ASCOT) program sponsored a field experiment in the winter of 1991 near Rocky Flats, Colorado. Both meteorological and tracer dispersion measurements were taken. These two data sets provided an opportunity to investigate the influence of terrain-generated, radiatively-driven flows on the dispersion of the tracer. We use the Regional Atmospheric Modeling System (RAMS), originally developed at Colorado State University, to simulate meteorological conditions and tracer dispersion on the case night of 4-5 February 1991. The simulations described herein reveal considerable information about the extent to which the Rocky Mountains influence the flow along the Front Range, the importance of diffusion when simulating drainage flows and the computing needs of simulations in complex terrain regions.
Download or read book The Application of High resolution Mesoscale Model Fields with the CALPUFF Dispersion Modelling System in Prince George B C written by and published by . This book was released on 2002 with total page 149 pages. Available in PDF, EPUB and Kindle. Book excerpt: Air pollution dispersion models that have been accepted by governments and used in regulatory decision-making normally require meteorological data to function. In many situations, the required data are not available and must be collected for a year or more before air quality modelling can begin. An alternative is to use a prognostic mesoscale model to construct meteorological fields in areas where little or no observations exist. This report describes a study to test the effectiveness of using one such model, the Regional Atmospheric Mesoscale Model (RAMS), in conjunction with the CALPUFF dispersion model to model dispersion in complex terrain where little or no meteorological data are available. Three five-day periods of moderate to high sulphur dioxide concentrations in a small area surrounding Prince George, British Columbia, in 1999 are used to test the performance of the model. CALPUFF dispersion estimates using the RAMS fields are compared to estimates determined using data from three surface and one upper-air meteorological stations within the test domain.
Download or read book Air Pollution Modeling written by P. Zannetti and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: Finishing this book is giving me a mixture of relief, satisfaction and frus tration. Relief, for the completion of a project that has taken too many of my evenings and weekends and that, in the last several months, has become almost an obsession. Satisfaction, for the optimistic feeling that this book, in spite of its many shortcomings and imbalances, will be of some help to the air pollution scientific community. Frustration, for the impossibility of incorporating newly available material that would require another major review of several key chap ters - an effort that is currently beyond my energies but not beyond my desires. The first canovaccio of this book came out in 1980 when I was invited by Computational Mechanics in the United Kingdom to give my first Air Pollution Modeling course. The course material, in the form of transparencies, expanded, year after year, thus providing a growing working basis. In 1985, the ECC Joint Research Center in Ispra, Italy, asked me to prepare a critical survey of mathe matical models of atmospheric pollution, transport and deposition. This support gave me the opportunity to prepare a sort of "first draft" of the book, which I expanded in the following years.
