Book Description
The report illustrates a research conducted using the HySPLIT chemical atmospheric transport model and the distribution of stable lights at night, to investigate the spatial patterns of atmospheric concentrations from continuous emissions spatially distributed as population. The analysis shows that a first approximation of the spatial distribution of concentrations may be obtained using the simple "4/3 power law" that Pistocchi and Galmarini, 2008, have shown to be able to approximate the plumes of annual average concentration depicted by the European model ADEPT. This finding enables to perform regional risk assessment taking into account the spatial distribution of receptors around, and not just at, the location of emissions, without the need to use complex transport numerical model, if one is interested in a first level of approximation (i.e., a factor 5 accuracy on concentrations, which is often compatible with the requirements of risk assessment). In such circumstances, the "4/3 power law" enables quick and simple back-of-the-envelope calculations, operationally equivalent to simple box model calculations.

Book Description
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 Description
This book is the standard reference based on roughly 20 years of research on atmospheric rivers, emphasizing progress made on key research and applications questions and remaining knowledge gaps. The book presents the history of atmospheric-rivers research, the current state of scientific knowledge, tools, and policy-relevant (science-informed) problems that lend themselves to real-world application of the research—and how the topic fits into larger national and global contexts. This book is written by a global team of authors who have conducted and published the majority of critical research on atmospheric rivers over the past years. The book is intended to benefit practitioners in the fields of meteorology, hydrology and related disciplines, including students as well as senior researchers.

Book Description
This volume presents a state-of-the-art assessment of the Earth's climate system in Siberia and relationships between climate, ecosystems and people in that region. Changes in climatic variables and land cover in Siberia are among the earliest indicators of the Earth’s response to climate warming. The volume is a compilation of results from studies on climate, land-cover and land-use changes and their interactions with biogeochemical and water cycles, atmospheric aerosol, and human and wildlife populations in Siberia. Regional changes in Siberia are predicted to affect climate and people on a global scale. NASA, the Russian Academy of Sciences, and several European institutions have supported these studies. The primary supporter of the projects that produced the results compiled in this volume is the NASA Land-Cover/Land-Use Change Program, hence most studies use remote sensing in their research. The chapters in this volume were written by an international team of scientists from the USA, Europe and Russia under the auspices of the Northern Eurasia Earth Science Partnership Initiative (NEESPI). This book will be of interest to those involved in studying recent and ongoing changes in Siberia, be they senior scientists, early career scientists or students.

Book Description
This Intergovernmental Panel on Climate Change Special Report is the most comprehensive assessment available on the effects of aviation on the global atmosphere. The report considers all the gases and particles emitted by aircraft that modify the chemical properties of the atmosphere, leading to changes in radiative properties and climate change, and modification of the ozone layer, leading to changes in ultraviolet radiation reaching the Earth. This volume provides accurate, unbiased, policy-relevant information and is designed to serve the aviation industry and the expert and policymaking communities.
