Laboratory of atmospheric processes and their impacts LAPI
Our lab studies atmospheric processes and their impacts on climate, health and ecosystems through a combination of theory, measurement and modelling. A central focus in our research program is atmospheric particulate matter (aerosols), and studies often combine observations, theory and modelling. We are involved in the development of aerosol instrumentation, and measurement techniques required to study processes and constrain parameters for models. Our group develops open-source modules routinely used in air quality and climate models, as well as tools for advanced sensitivity analysis of large codes and model reduction/data discovery through emulation and network analysis. We are also heavily involved in field measurement programs on understanding the climate and health impacts of ambient aerosol.
LAPI is very closely affiliated with the Center of Studies on Air quality and Climate Change (C-STACC) of the Institute of Chemical Engineering of the Foundation for Research and Technology Hellas at Patras (Greece) and the School of Earth and Atmospheric Sciences at the Georgia Institute of Technology (US), where the LAPI director maintains affiliations and active research groups and lab facilities. LAPI also maintains a large number of active collaborations with leading groups worldwide.

Towards a more affordable analysis of air pollution
EPFL scientists have developed a new method for chemical analysis of fine particles that they plan to extend on a large scale – including in developing countries – through an Innosuisse innovation grant award and a new startup.
Planting oats to study the effects of air pollution
A team of EPFL scientists turned Bois-Chamblard park in Buchillon, on Lake Geneva, into a temporary research station for collecting experimental data. Their goal is to better understand how anthropogenic air pollution affects plant growth.
LAPI contributed to an important paper on biomass burning pollution
Research by the teams of Prof. Athanasios Nenes (LAPI, EPFL and FORTH Greece) and Spyros Pandis of the Center for Studies on Air Quality and Climate Change (C-STACC; http://cstacc.iceht.forth.gr) of the Institute of Chemical Engineering Sciences at the Foundation for Research and Technology-Hellas (ICE-HT/FORTH; http://www.iceht.forth.gr) led to the discovery of a chemical mechanism that rapidly produces air pollution from biomass burning, during the night. This finding radically changes our view of pollution production from biomass combustion and may explain the paradoxically high levels of oxidized organic particles in urban areas during the winter. The results of the research, conducted under the European ERC program PyroTRACH (https://twitter.com/pyrotrach), can be found in Kodros et al. (here), published in the journal Proceedings of the National Academy of Sciences, USA.
