Sonla Hèzouwè is a PhD student in the chemistry department at the University of Lomé in Togo. He works on air quality with low cost sensors in the city of Lomé. 



YUANZHE LI (Patrick) is a Ph.D. student in the Graduate School of Science and Technology at
Sophia University. He participated in collaborative programs and received his bachelor's degrees at Nanjing Tech University in 2017 and at the University of Sheffield in 2018, respectively. He then participated in the SGU program in Japan and received his master's degree at Sophia University in 2021.



Bert Verreyken obtained his PhD in atmospheric physics and analytical chemistry in 2021. He is currently affiliated with the Royal Belgian Institute of Space Aeronomy (Brussels, BE) and the University of Liege – Gembloux Agro-Biotech (Gembloux, BE) where he aims to combine in situ measurements and modelling to study bi-directional exchange and of reactive trace gasses between ecosystems and the atmosphere. Before arriving in Belgium, Bert was an NRC fellow at Chemical Sciences Laboratory of the National Oceanic and Atmospheric Administration (Boulder, CO, USA).



Martin Otto Paul Ramacher is an early career scientist, working as junior group leader and postdoc in the chemistry transport modeling department of the environmental chemistry institute at the Helmholtz-
Zentrum hereon in Geesthacht, 



Worradorn Phairuang from Thailand is a faculty member of Atmospheric Environment and Pollution Control Engineering, Faculty of Geosciences and Civil Engineering, Kanazawa University, Japan. His  main research focuses on the chemical and physical characteristics of airborne nanoparticles (PM). His interests cover all the natural and anthropogenic sources, particularly biomass burning, including forest fire and agricultural residue burning. He is very interested in emission inventory from biomass burning in Thailand and Asian countries.



 Rachana is a highly respected independent air quality researcher with a strong focus on understanding the microphysical and chemical properties that influence air quality. She has made significant contributions to the field through her work on the Winter Fog Experiment (WiFEX) project at the IGI Airport in India, one of the busiest and most populated airports in the country. As part of the IGAC project, Rachana ensures that the team is meeting its goals and making meaningful contributions to the scientific community.



Dr. Tess Carter is a postdoctoral fellow at George Washington University, working on several projects, including characterizing the environmental justice impacts of PM2.5 and exploring the health ramifications of climate policies. She earned her PhD in atmospheric chemistry from MIT, where she worked on fires and how their smoke impacts air quality and climate, and a BS in chemistry from Brown University. Prior to graduate school, she worked on the National Climate Assessment for several years.



Sebastian Diez is currently a Research Associate at Wolfson Atmospheric Chemistry Laboratories (Uni of York, UK). His scientific interests focus on tools to support air quality decision-making processes and environmental justice issues and questions, especially in the Global South. During his PhD training, he has developed experience in field measurements/campaigns, modelling, and more recently in low-cost sensors. After his doctoral studies, he has been involved with regional NGOs and local governments in LatAm working on climate change and air quality projects.



Emily is a postdoctoral researcher at the University of Manchester and her research primarily focuses on the analysis of chemical ionisation mass spectrometer (CIMS) measurements made onboard the UK research aircraft. Her research interests lie in the marine sulphur and reduced nitrogen cycles. 



Sophie Szopa is an atmospheric chemist at the Laboratoire des Sciences du Climat et de l’Environnement. She uses numerical models to study how chemistry intervenes in the modification of the composition of the atmosphere and how this affects climate and air quality. She carried out work on these various current environmental issues, before becoming interested in the role of this chemistry in the distant past of the Earth.
