This book was released on 2019 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: The interactions between the biosphere and the atmosphere are an important controlling factor for regional to global atmospheric chemistry and composition. This ultimately has wide impacts on issues like air quality and climate change. However, there are still substantial uncertainties in the biosphere-atmosphere interaction processes that drive the global abundance and variability of many critically important atmospheric constituents, including ozone, aerosol, and Volatile Organic Compounds (VOCs). This thesis aims to address these uncertainties through a multifaceted approach, combining theory and data-driven models with observations. The scope of the research completed herein is introduced and described in Chapter 1. Chapter 2 is a case study of biosphere atmosphere interactions where the air quality impact of large-scale agricultural deforestation in Southeast Asia is investigating using global models. Chapters 3 and 4 focus on research toward improving model estimates of dry deposition, a process by which vegetation functions as a sink for atmospheric aerosol and reactive gas species. Chapter 3 constrains theoretical estimates of global dry deposition through comparison to a large suite of observations, in order to provide a detailed assessment of current theory. Chapter 4 develops a data-driven model for this process using "deep learning", an artificial intelligence-based regression method. This data-driven approach is nearly an order of magnitude more accurate than current theoretically based models. Chapter 5 focuses on assessing simulated impacts of biosphere-atmosphere interactions on atmospheric chemistry. Satellite observations of formaldehyde and glyoxal were used to constrain the chemical transformations relevant for VOC chemistry globally. In the final project, in Chapter 6, an improved representation of plant canopy processes for use in atmospheric chemistry simulations is developed, and its performance is assessed. Finally, Chapter 7 summarizes the work completed in this thesis.

This book was released on 2017-01-29 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our world is changing at an accelerating rate. The global human population has grown from 6.1 billion to 7.1 billion in the last 15 years and is projected to reach 11.2 billion by the end of the century. The distribution of humans across the globe has also shifted, with more than 50 percent of the global population now living in urban areas, compared to 29 percent in 1950. Along with these trends, increasing energy demands, expanding industrial activities, and intensification of agricultural activities worldwide have in turn led to changes in emissions that have altered the composition of the atmosphere. These changes have led to major challenges for society, including deleterious impacts on climate, human and ecosystem health. Climate change is one of the greatest environmental challenges facing society today. Air pollution is a major threat to human health, as one out of eight deaths globally is caused by air pollution. And, future food production and global food security are vulnerable to both global change and air pollution. Atmospheric chemistry research is a key part of understanding and responding to these challenges. The Future of Atmospheric Chemistry Research: Remembering Yesterday, Understanding Today, Anticipating Tomorrow summarizes the rationale and need for supporting a comprehensive U.S. research program in atmospheric chemistry; comments on the broad trends in laboratory, field, satellite, and modeling studies of atmospheric chemistry; determines the priority areas of research for advancing the basic science of atmospheric chemistry; and identifies the highest priority needs for improvements in the research infrastructure to address those priority research topics. This report describes the scientific advances over the past decade in six core areas of atmospheric chemistry: emissions, chemical transformation, oxidants, atmospheric dynamics and circulation, aerosol particles and clouds, and biogeochemical cycles and deposition. This material was developed for the NSF's Atmospheric Chemistry Program; however, the findings will be of interest to other agencies and programs that support atmospheric chemistry research.

This book was released on 1986-09-01 with total page 727 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers the proceedings of a study week held to bring together the most varied experiences in the many disciplines which form the background of ecology. The purpose of the meeting was to examine the present state of knowledge and the need for research in order to gather the information necessary for action to protect the environment and biosphere. Many aspects of the anthropogenic effects on the atmosphere have been studied. However more research is needed to quantify the impact of the various chemicals on the changes occurring in the atmosphere. Acid rain formation mechanisms, although investigated, are not yet fully understood. It is thus necessary to program carefully our future, after further interdisciplinary research, in order to avoid irreversible damage to our environment.The guidelines of this action, as a result of the presentations and discussions, are reported in the conclusions. The main points stressed are: tropospheric chemistry, the problem of the conservation of the ozone layer, the growth of carbon dioxide and climate changes, atmospheric acidity, the effects of changes on water, soils and biota as well as the particular problems of the tropical world. The book will be ideal for postgraduates studying atmospheric chemistry and for environmental protection agencies.

Available in PDF, EPUB and Kindle. Book excerpt: Climate change is one of the biggest challenges facing the modern world. The chemistry of the air within the framework of the climate system forms the main focus of this monograph. This problem-based approach to presenting global atmospheric processes begins with the chemical evolution of the climate system in order to evaluate the effects of changing air composition as well as possibilities for interference within these processes. Chemical interactions of the atmosphere with the biosphere and hydrosphere are treated in the sense of a multi-phase chemistry. From the perspective of a "chemical climatology" the book offers an approach to solving the problem of climate change through chemistry.

The overall objective of this project is to improve the understanding of coupling processes among atmospheric chemistry, aerosol and climate, all important for quantitative assessments of global change. Among our priority are changes in ozone and stratospheric sulfate aerosol, with emphasis on how ozone in the lower stratosphere would respond to natural or anthropogenic changes. The work emphasizes two important aspects: (1) AER's continued participation in preparation of, and providing scientific input for, various scientific reports connected with assessment of stratospheric ozone and climate. These include participation in various model intercomparison exercises as well as preparation of national and international reports. and (2) Continued development of the AER three-wave interactive model to address how the transport circulation will change as ozone and the thermal properties of the atmosphere change, and assess how these new findings will affect our confidence in the ozone assessment results.Ko, Malcolm K.

This book was released on 2017-02-22 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding the composition and chemistry of the Earth's atmosphere is essential to global ecological and environmental policy making and research. Atmospheric changes as a result of both natural and anthropogenic activity have affected many of the Earth's natural systems throughout history, some more seriously than others, and such changes are ever more evident with increases in both global warming and extreme weather events. Atmospheric Chemistry considers in detail the physics and chemistry of our atmosphere, that gives rise to our weather systems and climate, soaks up our pollutants and protects us from solar UV radiation.The development of the complex chemistry occurring on Earth can be explained through application of basic principles of physical chemistry, as is discussed in this book. It is therefore accessible to intermediate and advanced undergraduates of chemistry, with an interdisciplinary approach relevant to meteorologists, oceanographers, and climatologists. It also provides an ideal opportunity to bring together many different aspects of physical chemistry and demonstrate their relevance to the world we live in.This book was written in conjunction with Astrochemistry: From the Big Bang to the Present Day, Claire Vallance (2017) World Scientific Publishing.
