Book Description
Climate change and air quality are two of the most pressing concerns in the 21st century and VOCs play a pivotal role in both spheres. Scientists across the world are becoming aware of the importance of understanding the role that VOCs play from a wide range of fields. Atmospheric Sources and Sinks of Volatile Organic Compounds is comprehensive but concise book with information that is extremely important to groups in the field of atmospheric science but also to the myriad groups that border this field, such as climate scientists, analytical scientists, health professionals, agricultural and botanical related researchers and many more. Atmospheric Sources and Sinks of Volatile Organic Compounds provides the reader with information in a form that they can adapt, such as emission factors, ways to estimate emissions as a function of appropriate variables, removal processes etc. The research also is connected to topics allied fields including land use, agriculture, measurement (analytical), and climate science. Features datasets and global maps of VOC distributions with supporting data Provides readers with information so that they can carry out 'what if' calculations, to be able to estimate the change in emissions in the future or make the information relevant to their region of the world Includes comprehensive coverage of VOCs and demonstrations of patterns in emission and removal

Book Description
Every day, large quantities of volatile organic compounds (VOCs) are emitted into the atmosphere from both anthropogenic and natural sources. The formation of gaseous and particulate secondary products caused by oxidation of VOCs is one of the largest unknowns in the quantitative prediction of the earth’s climate on a regional and global scale, and on the understanding of local air quality. To be able to model and control their impact, it is essential to understand the sources of VOCs, their distribution in the atmosphere and the chemical transformations which remove these compounds from the atmosphere. In recent years techniques for the analysis of organic compounds in the atmosphere have been developed to increase the spectrum of detectable compounds and their detection limits. New methods have been introduced to increase the time resolution of those measurements and to resolve more complex mixtures of organic compounds. Volatile Organic Compounds in the Atmosphere describes the current state of knowledge of the chemistry of VOCs as well as the methods and techniques to analyse gaseous and particulate organic compounds in the atmosphere. The aim is to provide an authoritative review to address the needs of both graduate students and active researchers in the field of atmospheric chemistry research.

Book Description
Earth's atmosphere holds a mass of organic compounds, which differ by orders of magnitude regarding fundamental properties such as volatility, reactivity, and propensity to form cloud droplets, affecting their impact on global climate and human health. Volatile organic compounds (VOCs) play a vital role in the chemistry of the atmosphere by impelling ozone and hydroxyl radical (OH) concentrations and the renovation rates of nitrogen oxides (NOx). Elevated levels of VOCs and NOx have led to an approximate doubling of ozone in the lower troposphere over the past couple of centuries, making tropospheric ozone the third most important anthropogenic greenhouse gas after carbon dioxide (CO2) and methane. Monitoring of volatile organic compounds (VOCs) is a key piece in understanding photochemical air quality in urban atmosphere. Anthropogenic sources such as incomplete combustion of organic substances, the use of petrochemical solvents, and vaporizations of petroleum products are sources of VOCs. Every day, large quantities of volatile organic compounds (VOCs) are emitted into the atmosphere from both anthropogenic and natural sources. Therefore, their sources, sinks and dwelling times are the subject of current research. Atmospheric Degradation of Organic Substances describes the current state of knowledge of the chemistry of VOCs as well as the methods and techniques to analyze gaseous and particulate organic compounds in the atmosphere. The book also includes evaluation of the relative ozone-forming potentials of the captured VOC species in the atmosphere of urban settlement. The analytical toolbox available for chemists to study atmospheric organic compounds has expanded considerably during the past decade, opening new windows into speciation, time resolution and detection of reactive and semi-volatile compounds at low concentrations. This has provided unprecedented opportunities, but also revealed new scientific challenges.This book is of interest to students, practitioners, as well as guiding tool for researchers in the field of atmospheric research.

Book Description
The oceans and atmosphere interact through various processes, including the transfer of momentum, heat, gases and particles. In this book leading international experts come together to provide a state-of-the-art account of these exchanges and their role in the Earth-system, with particular focus on gases and particles. Chapters in the book cover: i) the ocean-atmosphere exchange of short-lived trace gases; ii) mechanisms and models of interfacial exchange (including transfer velocity parameterisations); iii) ocean-atmosphere exchange of the greenhouse gases carbon dioxide, methane and nitrous oxide; iv) ocean atmosphere exchange of particles and v) current and future data collection and synthesis efforts. The scope of the book extends to the biogeochemical responses to emitted / deposited material and interactions and feedbacks in the wider Earth-system context. This work constitutes a highly detailed synthesis and reference; of interest to higher-level university students (Masters, PhD) and researchers in ocean-atmosphere interactions and related fields (Earth-system science, marine / atmospheric biogeochemistry / climate). Production of this book was supported and funded by the EU COST Action 735 and coordinated by the International SOLAS (Surface Ocean- Lower Atmosphere Study) project office.

Book Description
The stability of forest ecosystems is affected by changes of environment conditions, like by increasing temperatures, increasing atmospheric CO2 and decreasing deposition rates of nutrients and acidity. This volume integrates the results of long term interdisciplinary ecosystem research at two forested watersheds in Germany with special emphasis on the biogeochemistry of carbon, dissolved organic matter and mineral elements in response to changing environmental conditions and management. Despite the reduction in acidic deposition, forest ecosystems are still threatened by soil acidification, nutrient depletion and eutrophication and criteria of sustainability are not yet achieved. The results highlight the complex interactions between vegetation, animals and soils in terrestrial ecosystems that are triggered by changes in environmental conditions.
