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).

Mission

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.

LAC Mission
LAC's mission

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.

Research above – and about – the clouds

Environment Energy and Climate

At the Jungfraujoch research station, PSI scientists study particulate matter in the atmosphere. And have to deal with the fact that the human body is not made for life at 3,500 metres above sea level.

Environment Energy and Climate

PSI researchers drill through millennia-old glacier ice in the high mountains and analyse the world's highest particulate concentrations in Delhi, India. They are helping to address questions regarding climate change and to reduce air pollution.
