Fundamental atmospheric chemistry research provides essential data used in all practical (laboratory, field measurements, remote sensing) and theoretical (climate modeling, pollution modeling, cloud microphysics) aspects of scientific endeavor.


SPARTAN was an IGAC sponsored activity from 2016-2018

Fine particulate matter (PM2.5) is a leading risk factor for premature mortality. Additional attention is needed to improve global estimates of PM2.5 exposure.


Under the guiding principle of providing equal opportunity for all scientists in the Americas, the IGAC Americas Working Group aims to build a cohesive network and foster the next generation of atmospheric scientists with the ultimate goal of contributing to development of a scientific community focused on building collective knowledge in/for the Americas. There is a priority on bringing together scientists from across the entirety of the Americas. To this end, the Americas Working Group seeks to:


The sheer magnitude of China's landmass coupled with its growing and economically advancing population makes it critical to understand its role in air quality and climate on both regional and global scales. Chinese atmospheric chemists have been conducting frontier research for forty years in areas such as urban and regional air pollution and the climate effects and health impacts of air pollution. IGAC intends to more fully integrate Chinese research experience by establishing its first national working group in China. The goals of the IGAC China Working Group are to:


Prof. Dr. Noureddine Yassaa is the Director of "Centre de Développement des Energies Renouvelables" in Algeria. He is also a Professor of Chemistry at the University of Science and Technology Houari Boumediene (USTHB) in Algiers, Algeria and leading a research group in Environmental Science. He received his doctorate in Chemistry in 2001 from the University USTHB. He conducted some of his doctoral research at the Institute for Atmospheric Pollution, National Research Council (IIA-CNR) in Rome, Italy.



Tao Wang is a professor at the Department of Civil and Environmental Engineering of the Hong Kong Polytechnic University (PolyU). He received his PhD in Atmospheric Chemistry at Georgia Institute of Technology in 1992 and then conducted postdoctoral research at University of Michigan-Ann Arbor. His earlier work was field investigation of reactive nitrogen and ground-level ozone, in association with the SOS, NARE, and PEM-West programs.



Spyros Pandis is Professor in the Chemical Engineering Department of the University of Patras in Greece and Research Professor of Chemical Engineering and Engineering and Public Policy in Carnegie Mellon University. He received his PhD from the California Institute of Technology in 1991 and joined the faculty of Carnegie Mellon University in 1993 and of the University of Patras in 2004. His research includes theoretical and experimental studies of atmospheric chemistry as it relates to urban and regional pollution and topics related to global climate change.



Kim Oanh is a professor at Environmental Engineering and Management (EEM), Asian Institute of Technology (AIT), Thailand. She got Dipl. Eng. in Meteorology (1978) from Odessa Hydrometeorology Institute, Ukraine; M. Eng. (1991) and Dr. Eng. (1994) in Environmental Technology and Management from AIT, Thailand. She has started her work as a faculty member at AIT since 1997, focusing on teaching and research in air pollution engineering and management.



Jennifer Murphy is an Associate Professor in the Department of Chemistry at the University of Toronto, where she has held a Canada Research Chair since 2007. Her doctoral studies at the University of California, Berkeley (2000-2005) focused on measurements and analyses of nitrogen oxides and ozone. As a postdoctoral fellow at the University of East Anglia (2005-2006), she made measurements of volatile organic compounds from the British research aircraft during the AMMA campaign in West Africa.



Alastair is currently professor of atmospheric science at University of York and Science Director at the UK National Centre for Atmospheric Science. He is a Fellow of the Royal Society of Chemistry and has held their John Jeyes lectureship in Environment, Energy and Sustainability. Alastair's research expertise is in reactive atmospheric chemistry, particularly that of organic compounds in the troposphere and their role in health, ozone and aerosols.
