This book states that current developments in air pollution modeling are explored as a series of contributions from researchers at the forefront of their field. This newest contribution on air pollution modeling and its application is focused on local, urban, regional and intercontinental modeling; long-term modeling and trend analysis; data assimilation and air quality forecasting; model assessment and evaluation; aerosol transformation. Additionally, this work also examines the relationship between air quality and human health and the effects of climate change on air quality.

This work is a collection of selected papers presented at the 39th International Technical Meeting on Air Pollution Modeling and its Application, held in Chapel Hill, North Carolina, USA, May 22-26, 2023.

The book is intended as reference material for students and professors interested in air pollution modeling at the graduate level as well as researchers and professionals involved in developing and utilizing air pollution models.

Professor Clemens Mensink is research director of the Environmental Intelligence unit at VITO in Belgium. VITO is an independent Flemish research organization in the area of cleantech and sustainable development with the goal to accelerate the transition to a sustainable world. Clemens received his PhD (1992) and a post graduate degree (1988) in fluid dynamics from the Von Karman Institute in Belgium. He studied chemical engineering, fluid mechanics and numerical mathematics, and received his MSc (1987) in mechanical engineering from University of Twente in the Netherlands. In 1998 he received the ENERO prize. Clemens currently serves as president of the International Technical Meeting on Air Pollution Modeling and its Applications. He is an expert in air pollution modeling and author of more than 80 peer-reviewed publications in international journals. He is professor atmospheric modeling at Ghent University in Belgium.

Dr. Rohit Mathur is a Senior Scientist with the Office of Research and Development, U.S. Environmental Protection Agency. His research deals with the development of novel methods to understand and represent the physical and chemical behavior of atmospheric pollutants in comprehensive modeling frameworks. His work has contributed to the development and continued scientific evolution of several large-scale air pollution modeling systems widely used in research and regulatory applications. During his tenure both at EPA and in prior positions at research and academic institutions, he has served in numerous leadership and science management roles. He holds a B.E. (from the Birla Institute of Technology and Science, India) and M.S. and Ph.D. (from the University of Kentucky, USA) in Chemical Engineering. He serves on the scientific committee of the International Technical Meeting on Air Pollution Modeling and Its Applications and hosted the 2023 meeting at which the papers in this book, were presented.

Saravanan Arunachalam is Deputy Director and Research Professor with the UNC Institute for the Environment (UNC-IE) and Adjunct Professor at the UNC Gillings School of Public Health's Department of Environmental Sciences and Engineering. UNC-IE develops multidisciplinary collaborations to understand major environmental issues and engages myriad academic disciplines, public and private partners, and an informed and committed community. Within UNC-IE, he directs the Center for Environmental Modeling for Policy Development (CEMPD) which provides a resource for developing multi-scale applications and research on emissions and air quality modeling. Arunachalam also directs the U.S. EPA funded Center for Community Modeling and Analyses System (CMAS) and the U.S. DOT funded Aviation Sustainability Center (ASCENT) at UNC. The CMAS center supports a global user community of modelers who use air quality models for both scientific as well as regulatory applications. He also contributes to international policymaking under the United Nations ICAO's Committee on Aviation Environmental Protection (CAEP) through being an invited member of the Impacts and Sciences Group (ISG) focused on aviation air quality impacts and written policy papers. Dr. Arunachalam received his Ph.D. (1998) and M.S. (1993) in Chemical Engineering from Rutgers, the State University of New Jersey and B.Tech. (1989) in Chemical Engineering from Anna University, India. He is an expert on multi-scale modeling techniques for source apportionment and impact assessment. Dr. Arunachalam has published nearly 100 papers and given > 200 oral presentations, many of them invited.
