About the project
ACTRIS-Switzerland is the Swiss node of the ACTRIS European Research Infrastructure Consortium

The ACTRIS network aims to deepen our understanding of climate change and air pollution by producing high-quality observation data on short-lived atmospheric constituents such as atmospheric aerosols, reactive trace gases, and clouds.
ACTRIS-Switzerland makes an outstanding contribution to this network thanks to its combination of advanced research facilities and its exceptional geographical location covering the central Alps.

Hazy days in Switzerland
Despite the fine weather across Switzerland this week, many observers have noted the poor sky visibility and startling red sunsets. These are the effects of two atmospheric constituents that visited us from far away locations. Our first visitor arrived last…
Switzerland formally decides to become a full member of the ACTRIS ERIC
ACTRIS Switzerland reached a major milestone this week with the Swiss Federal Council formally deciding to join the ACTRIS ERIC on April 9, 2025. This decision solidifies Switzerland’s role in ACTRIS and paves the way for ACTRIS Switzerland to transition…
Payerne National Facility receives a major new upgrade in cloud remote sensing
Last week saw a major step forward in observation by ACTRIS-Switzerland: a radar dedicated to the remote sensing of clouds in the atmosphere was installed by the University of Bern at the National Facility in Payerne, hosted by MeteoSwiss. This…
Comparing ultrafine particle measurements on the Jungfraujoch
A variety of different methods are used to measure the size distributions of the smallest aerosol particles in the atmosphere — so called ultrafine particles, or UFPs. One promising new, lightweight and handheld device is the Partector 2 Pro manufactured…
