Life on Earth is critically dependent upon the continuous cycling of water between oceans, continents and the atmosphere. Precipitation (including rain, snow, and hail) is the primary mechanism for transporting water from the atmosphere back to the Earth’s surface. It is also the key physical process that links aspects of climate, weather, and the global hydrological cycle. Changes in precipitation regimes and the frequency of extreme weather events, such as floods, droughts, severe ice/snow storms, monsoon fluctuations and hurricanes are of great potential importance to life on the planet. One of the factors that could contribute to precipitation modification is aerosol pollution from various sources such as urban air pollution and biomass burning. Natural and anthropogenic changes in atmospheric aerosols might have important implications for precipitation by influencing the hydrological cycle, which in turn could feed back to climate changes. From an Earth Science perspective, a key question is how changes expected in climate will translate into changes in the hydrological cycle, and what trends may be expected in the future. We require a much better understanding and hence predictive capability of the moisture and energy storages and exchanges among the Earth’s atmosphere, oceans, continents and biological systems. This book is a review of our knowledge of the relationship between aerosols and precipitation reaching the Earth's surface and it includes a list of recommendations that could help to advance our knowledge in this area.

Erstmals liegt nun im deutschsprachigen Raum ein Buch vor, das umfassend über alle Aspekte der Luft als wichtigstes Umweltmedium informiert. Der Autor bringt 30 Jahre eigene atmosphärische Umweltforschung und 15 Jahre Vorlesungstätigkeit zur Luftchemie als Erfahrung ein. Neben der Darstellung der wichtigen Grundlagen zum besseren Verständnis atmosphärischer Prozesse wird vor allem Wert auf die Erläuterung komplexer Zusammenhänge zwischen Ursachen und Wirkungen der Luftverschmutzung gelegt. Durch ein kritisches Hinterfragen gängiger Meinungen bietet das Buch neue Gedanken zur langfristigen Lösung (nicht nur) atmosphärischer Umweltprobleme. Das Werk eignet sich als Handbuch, Nachschlagewerk und studienbegleitendes Lehrbuch. Es ist daher ideal für Meteorologen, Chemiker, Physiker, Geographen, Geoökologen, Umweltingenieure, Verfahrenstechniker, Juristen, Verwaltungsfachleute und alle am Medium Luft Interessierten, aber auch für jeden, der sich für Umweltfragen interessiert. "Luft" hat das Potenzial zum Standardwerk für den Praktiker unter den Fachleuten, wie schon das Nachschlagewerk "Wasser" von Professor A. Grohmann. Auch hier ist es erneut gelungen, neben der Faszination für diesen "Mikrokosmos" die hohe wissenschaftliche Kompetenz einzubringen, um die Grundlagen zahlreicher Spezialdisziplinen rund um die Luft verständlich darzustellen. Ausführlich und auf aktuellstem Niveau wird anschaulich vermittelt, dass Luft eben sehr viel mehr ist als nur "ein Gasgemisch mit darin suspendierten Teilchen".

Today, indoor mold and moisture, and their associated health effects, are a society-wide problem. The economic consequences of indoor mold and moisture are enormous. Their global dimension has been emphasized in several recent international publications, stressing that the most important means for avoiding adverse health effects is the prevention (or minimization) of persistent dampness and microbial growth on interior surfaces and in building structures.This book aims to describe the fundamentals of indoor mold growth as a prerequisite to tackle mold growth in the existing building stock as well as in future energy efficient buildings. It brings together different disciplinary points of view on indoor mold, ranging from physics and material science to microbiology and health sciences. The contents have been outlined according to three main issues: Fundamentals, particularly addressing the crucial roles of water and materials, Health, including a state-of-the-art description of the health-related effects of indoor molds, and Strategies, integrating remediation, prevention and policies.

Aerosols in workplace atmospheres have been - and continue to be - a major focus of industrial hygiene. Although there are many existing texts on aerosol science and on occupational health respectively, this new book sets out to be complementary to these and to provide a link between the two fields. In particular, the central concept of worker exposure leads to a structured approach which draws together wide-ranging aspects of aerosol science within the occupational health framework. Introductory chapters are concerned with the nature and properties of aerosols, and how they are generated in the occupational environment. The book then goes on to provide a description of the fundamental mechanical properties of aerosols, in particular those mechanical properties associated with the motion of airborne particles (which govern particle transport, inhalation, deposition, sampling and control). There follows a description of the optical properties of workplace aerosols since these are important in the visual appearance of aerosols and in many aspects of measurement. The central core of the book deals with the processes which govern the nature of exposure to and the subsequent fate and effects of airborne particles, leading to a rational framework for standards, measurement and control. Finally, a chapter is added which relates what has been said about aerosols to gaseous and vapour contaminants. The book is aimed at graduate students and practitioners in industrial hygiene and other occupational (and environmental) health disciplines.

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.
