During the past 30 years, there have been advances in the understanding of multi-particle hydrodynamic interactions in the field of aerosol dynamics. Aerosol dynamics is developing from isolated-particle stage into multi-particle stage. This book reviews these progresses, and the subjects it covers include sedimentation, coagulation, mass or heat transfer, effective viscosity, and the evolution of the size distribution.

During the past 30 years, there have been advances in the understanding of multi-particle hydrodynamic interactions in the field of aerosol dynamics. Aerosol dynamics is developing from isolated-particle stage into multi-particle stage. This book reviews these progresses, and the subjects it covers include sedimentation, coagulation, mass or heat transfer, effective viscosity, and the evolution of the size distribution.

Using the aerosol dynamics approach, the author integrates a broad range of topics including stochastic processes, aerosol transport theory, coagulation, formation of agglomerates, classical nucleation theory, and the synthesis of ultrafine solid particles. The book makes extensive use of scaling concepts and dimensional analysis and emphasizes physical and physicochemical interpretations.

This concise overview of issues related to air quality starts with basic principles of physics and chemistry and moves to a discussion of the latest science around such issues as radiative transfer, atmospheric boundary layer and chemistry transport models.

An Introduction to Clouds provides a fundamental understanding of clouds, ranging from cloud microphysics to the large-scale impacts of clouds on climate. On the microscale, phase changes and ice nucleation are covered comprehensively, including aerosol particles and thermodynamics relevant for the formation of clouds and precipitation. At larger scales, cloud dynamics, mid-latitude storms and tropical cyclones are discussed leading to the role of clouds on the hydrological cycle and climate. Each chapter ends with problem sets and multiple-choice questions that can be completed online, and important equations are highlighted in boxes for ease of reference. Combining mathematical formulations with qualitative explanations of underlying concepts, this accessible book requires relatively little previous knowledge, making it ideal for advanced undergraduate and graduate students in atmospheric science, environmental sciences and related disciplines.

The #1 guide to aerosol science and technology -now better than ever Since 1982, Aerosol Technology has been the text of choice among students and professionals who need to acquire a thorough working knowledge of modern aerosol theory and applications. Now revised to reflect the considerable advances that have been made over the past seventeen years across a broad spectrum of aerosol-related application areas - from occupational hygiene and biomedical technology to microelectronics and pollution control -this new edition includes: * A chapter on bioaerosols * New sections on resuspension, transport losses, respiratory deposition models, and fractal characterization of particles * Expanded coverage of atmospheric aerosols, including background aerosols and urban aerosols * A section on the impact of aerosols on global warming and ozone depletion. Aerosol Technology, Second Edition also features dozens of new, fully worked examples drawn from a wide range of industrial and research settings, plus new chapter-end practice problems to help readers master the material quickly.

The subject of aerosols goes back many years and enters many aspects of science and technology. Optics, heat-transfer, biology, meteorology and pollution are just a few areas where the behaviour of small particles suspended in a gas is of vital importance. More recently, with increasing concern about the consequences of accidents in nuclear reactors and the effect of global nuclear war (i.e., the nuclear winter) a great deal of work has been directed towards the dispersal of radioactive aerosols in closed containers and in the atmosphere. The purpose of the book is twofold: to give a thorough treatment of the fundamentals of aerosol behaviour with rigorous proofs and detailed derivations of the basic equations and removal mechanisms and also to give practical examples with special attention to radioactive particles and their distribution in size following a release arising from an accident with a nuclear system. This book will be useful both as a course text and as a reference source.

The ever-diversifying field of aerosol effects on climate is comprehensively presented here, describing the strong connection between fundamental research and model applications in a way that will allow both experienced researchers and those new to the field to gain an understanding of a wide range of topics. The material is consistently presented at three levels for each topic: (i) an accessible "quick read" of the essentials, (ii) a more detailed description, and (iii) a section dedicated to how the processes are handled in models. The modelling section in each chapter summarizes the current level of knowledge and what the gaps in this understanding mean for the effects of aerosols on climate, enabling readers to quickly understand how new research fits into established knowledge. Definitions, case studies, reference data, and examples are included throughout. Aerosols and Climate is a vital resource for graduate students, postdoctoral researchers, senior researchers, and lecturers in departments of atmospheric science, meteorology, engineering, and environment. It will also be of interest to those working in operational centers and policy-facing organizations, providing strong reference material on the current state of knowledge. - Includes a section in each chapter that focuses on the treatment of relevant aerosol processes in climate models - Provides clear exposition of the challenges in understanding and reducing persistent gaps in knowledge and uncertainties in the field of aerosol-climate interaction, going beyond the fundamentals and existing knowledge - Authored by experts in modeling and aerosol processes, analysis or observations to ensure accessibility and balance

Ein Blick auf die morphologischen, physikalischen und chemischen Eigenschaften von Aerosolen aus den unterschiedlichsten natürlichen und anthropogenen Quellen trägt zum besseren Verständnis der Rolle bei, die Aerosolpartikel bei der Streuung und Absorption kurz- und langwelliger Strahlung spielen. Dieses Fachbuch bietet Informationen, die sonst schwer zu finden sind, und vermittelt ausführlich die Kenntnisse, die erforderlich sind, um die mikrophysikalischen, chemischen und Strahlungsparameter zu charakterisieren, die bei der Wechselwirkung von Sonnen- und Erdstrahlen so überaus wichtig sind. Besonderes Augenmerk liegt auf den indirekten Auswirkungen von Aerosolen auf das Klima im Rahmen des komplexen Systems aus Aerosolen, Wolken und der Atmosphäre. Auch geht es vorrangig um die Wirkungen natürlicher und anthropogener Aerosole auf die Luftqualität und die Umwelt, auf die menschliche Gesundheit und unser kulturelles Erbe. Mit einem durchgängig lösungsorientierten Ansatz werden nicht nur die Probleme und Gefahren dieser Aerosole behandelt, sondern auch praktikable Lösungswege aufgezeigt.
