He has the distinction of developing and commissioning the first air quality Forecasting system for Indian Mega cities which is recognised as a pilot project of the World Meteorological Organisation (WMO-GURME). He is the recipient of several awards, viz. the coveted Shanti Swarup Bhatnagar Award, Norbert Gerbier-Mumm International Award of WMO, etc. He has been a committee member of the scientific steering /advisory committee member of the International Global Atmospheric Chemistry (IGAC) project; SPARC of World Climate research; and Global Atmospheric Watch’s GURME-WMO project.
Paul Beukes (JP Beukes) is full professor in Chemistry at the North-West University (NWU), Potchefstroom, South Africa. He received his PhD (Chemistry) in 1999 from the then Pothefstroom University for CHE. Paul worked in the metallurgical industry for almost a decade after completing his PhD, holding various senior positions such a production manager and operations manager at large ferrochromium smelters. In late 2007 he returned to academia and is currently co-managing the Atmospheric Chemistry Research Group (ACRG) and Chromium Technology Groups (CTG) at the NWU. The ACRG focuses mostly on in situ ambient atmospheric measurements, but research related to laboratory investigations, satellite observations and modelling is also conducted, while the CTG concentrate on metallurgical process improvements with associated atmospheric and/or other environmental co-benefits, e.g. reduced energy consumption, smaller carbon footprint and reduced water pollution. Paul is a South African National Research Foundation (NRF) rated scientist and serves on many advisory boards for industry, government and academia. Probably the most noteworthy panel that he is currently serving on is the International Global Atmospheric Chemistry (IGAC) scientific steering committee (SSC).
Full Professor of Environmental Chemistry at the University of Perugia. Coordinator of the Environmental Chemistry and Technology (ECT) research group. Member of the Italian Glaciological Committee (CGI) and Italian Aerosol Society (IAS). He participated in several Italian Arctic Expeditions (2011-2019). Italian delegate at the Arctic Science Forum Ministerial (Berlin, 2018).
Co-author of more than 150 scientific ISI publications, including well-renowned international journals of high impact factor (such as Nature, Angewandte Chemie, Journal of the American Chemical Society, Physical Review Letters, Atmospheric Chemistry and Physics). He has contributed to important review papers (Accounts of Chemical Research, International Reviews in Physical Chemistry, Progress in Surface Science, Advances in Quantum Chemistry).
Lead Editor of the Special Issues "Environmental Changes in the Arctic: an Italian Perspective" appeared on Rendiconti Lincei (2016, Springer) and "Mineral Dust: Sources, Atmospheric Processing and Impacts" appeared on Atmosphere (2018, MDPI).
Research in the ECT group is based on the chemical and morphological characterization of atmospheric aerosols in the urban, remote and indoor environments, vertical profile measurements of aerosol properties by tethered balloon experiments and aerosol source apportionment methodologies, implementation and optimization of chemical transport models (Lagrangian and Eulerian).
My work involves numerical modelling of air pollution chemistry, mainly in the indoor environment, and to a lesser extent, outdoors. My indoor air chemistry work involves investigating the chemical processes that cause high concentrations of air pollutants indoors, particularly those pollutants that are likely to be harmful to health. Topics of interest are the impacts of human activities on indoor air quality, such as cooking, cleaning and DIY activities such as painting. We also investigate the impact of emissions from common indoor materials such as carpet and wooden furnishings on indoor air quality.
Tianfeng Chai is an Associate Research Scientist at CICS-MD and the Department of Atmospheric & Oceanic Science, University of Maryland, College Park, Maryland, USA. He got his master and bachelor degrees from Tsinghua University in Beijing, majoring in Fluid Mechanics, Engineering Mechanics, and Environmental Engineering. He earned his Ph.D. at the University of Iowa, with his dissertation of "Four-Dimensional Variational Data Assimilation Using Lidar Data" focusing on atmospheric boundary flow. He then worked with Dr. Greg Carmichael to develop chemical transport model adjoints and computational framework for data assimilation applications before moving to working on the NOAA National Air Quality Forecast Capability (NAQFC) project in 2007. He currently works on the inverse modeling problems using HYSPLIT (Hybrid Single Particle Lagrangian Integrated Trajectory Model) to support several projects at NOAA Air Resources Laboratory.
Professor of Atmospheric Chemistry and Head of the Atmospheric Science Department at Colorado State University. Chair, American Meteorological Society Atmospheric Chemistry Committee. Member, USDA Agricultural Air Quality Task Force. Board Member, International Fog and Dew Association. Chair, American Association for Aerosol Research Awards Committee.
Associate Professor Ross Edwards is a researcher with Curtin University Physics and Astronomy investigating the present and glacial time-scale deposition history of smoke and other aerosols from the global atmosphere. These particles alter the properties of the atmosphere influencing climate, atmospheric chemistry, and the productivity of the biosphere. His expertise ranges from the ultra-trace chemical and isotopic analysis of polar ice and snow, and terrestrial and marine waters to conducting field campaigns in the Earth’s most extreme environments. As an inventor, he has pioneered new analytical methods and created equipment that has allowed the continuous analysis of ice cores at the parts per quadrillion level and the ultra-trace analysis of black carbon in water.
Professor of Environmental Science and Engineering, specialized in atmospheric chemistry (in particular aerosol characterization and air pollution), environmental chemistry, chemical thermodynamics, solid waste ultilization etc. He has published more than 100 SCI paper in the field of environmental science, with >50 of them being the first or corresponding authors, with a total ISI citation over 2000 times.
Associate Professor, Department of Civil, Construction and Environmental Engineering, North Carolina State University.
Research interests include the sources and evolution of atmospheric aerosols, characterization of in-use emissions from mobile and stationary combustion sources, linkages between air pollution emissions and climate change, air pollution exposure assessment, technical policy analysis of the environmental impacts of energy systems, and energy and environment in developing countries.
NCAS-Climate researcher in atmospheric composition. Since 2009 I have been working on numerical simulation of the atmosphere, focussing on the chemistry of the troposphere. My main interests are in halogens, NOx and heterogeneous chemistry. I am also interested in model-measurement comparisons and ways to quantify and improve model treatments of atmospheric composition.
