LAC - Laboratory of Atmospheric Chemistry
The Laboratory of Atmospheric Chemistry (LAC), established 1 January 2000, is a laboratory of the Energy and Environment Research Division (ENE) at the Paul Scherrer Institute (PSI).
Understanding the processes determining the gas and aerosol chemistry and aerosol physics in the atmosphere in order to determine (1) the impact of energy use on the atmosphere and (2) the impact of pollution on air quality, human health, local weather and climate change.
Our laboratory consists of four interacting groups that operates cutting-edge facilities and instrumentations in the lab and in the field. We run three National facilities, two ambient observatories and an atmospheric chamber facility, that are foreseen to be included in the ACTRIS European research infrastructure. We study the impact of anthropogenic air pollution across environments ranging from cities in Europe and developing countries (e.g. India and China) to pristine areas (e.g. in polar regions and in the free troposphere). We are continuously measuring key climate variables relevant for aerosol properties at the landmark high-alpine Jungfraujoch research site in Switzerland. We simulate the processes occurring in the atmosphere in our smog chamber facility and during experiments at the CLOUD chamber at CERN. Field and laboratory data are interpreted and air pollution sources are quantified with numerical and statistical models. We collaborate with toxicologists, epidemiologists and medical doctors to understand the impact of air pollution on health.

Successful Ambizione Grant Applicant
Kaspar Dällenbach, Scientist at the Laboratory of Atmospheric Chemistry (LAC) at the Paul Scherrer Institute (PSI) was granted the Ambizione Grant 2020 with his project “Particulate air pollution sources in low-income megacities (PRESSING)”.
Successful Ambizione Grant applicant
Patrik Winiger, Research Grant Advisor and Project Manager at ETH Zurich, successfully applied for the Ambizione Grant 2020 with the project “Macromolecular Aerosols in the Cryosphere from the Arctic to the Alps – MACrAA”. The idea was developed together with the Laboratory for Atmospheric Chemistry (LAC) at PSI. The LAC is a global leader in aerosol analytics and source identification. They own and operate a unique laboratory infrastructure with various instruments and multiple aerosol simulation chambers available for researchers.
