This volume contains the invited papers and a transcript of the final panel discussion in the First Scientific Conference of the International Global Atmospheric Chemistry (lGAC) Project, held in Eilat, Israel from April 18-22, 1993. The conference was hosted by the Israeli Institute for Biological Research (IIBR) and was the 37th in the prestigious OHOLO Conference series in Israel. The conference was devoted to the subject of "Global Atmospheric-Biospheric Chemistry" and was a landmark event in this area. It provided the first comprehensive report of progress under IGAC toward improving our understanding of the chemical and biological processes that determine the changing composition of the earth's atmosphere. This work is an essential component of the comprehensive International Geosphere Biosphere Program (lGBP) devoted to measuring and understanding global changes in the past and present, and predicting the future evolution of our planet. I want to devote this brief foreword to thanking several people who worked especially hard to make the conference a success and who helped to produce this volume as a record of the event. Paul Crutzen, Amram Golombek, Pamela Matson and Henning Rodhe did sterling service on the conference organizing committee. Special thanks go to Amram Golombek and Dr. Cohen, the Director of IIBR, who hosted the event in Israel. Anne Slinn did an excellent job in producing the Abstract book and helping with administrative matters. Alex Pszenny helped capably to critically review the Abstracts.

Praise for Guy P. Brasseur's Atmospheric Chemistry in a Changing World American Meteorological Society "This volume summarizes and integrates more than a decade of atmospheric chemistry research. During the period under consideration, great progress has been made in computing, modeling, and observational techniques, and methods have also improved. Here, suggestions for the highest priority research for the next decade are made, and important information is related regarding impacts on the environment."

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.

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.

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.
