ACTRIS facilitates cooperation across borders. A great example of this is SACA-ACTRIS: a joint project between ACTRIS-CH and ACTRIS-CZ funded by the Swiss-Czech Cooperation Programme. SACA-ACTRIS aims to upgrade aerosol and trace‑gas monitoring with new aerosol optics, source‑apportionment, and QA/QC tools, delivering high‑resolution black‑carbon maps and improved VOC measurements for…
Last week the ACTRIS community congregated in Oslo, Norway for the ACTRIS Science Conference 2026. This bienniel conference provides an opportunity to present and discuss the latest ACTRIS-related science. ACTRIS-Switzerland was very well-represented at the event.
Several ACTRIS Switzerland members attended this year’s ACTRIS Week meeting in Evora, Portugal. ACTRIS Week is an important chance for the ACTRIS community to come together and share updates about recent and ongoing ACTRIS progress, projects, and challenges. At this year’s meeting ACTRIS Switzerland member Dr. Cuiqi Zhang took on…
Following installation of the new fog monitor, the Jungfraujoch National Facility has been initially accepted for Cloud in situ measurements by the ACTRIS ERIC Director General on 6 October, 2025. From this date on, the instruments used and data provided by the facility are officially under the operation supported by…
The team at PMOD/WRC have had a busy month in Davos with the 6th Filter Radiometer Comparison campaign for Aerosol Optical Depth (AOD) measurements, which was held from 20 September to 10 October 2025. This campaign was organized by the PMOD/WRC and supported by the World Meteorological Organization. It was…
TOFWERK is a Swiss-based company that designs and manufacturers high-quality mass spectrometers for characterizing atmospheric composition. Recently, the company has developed a robust new instrument for monitoring VOCs (volatile organic compounds) in real time: the AirTox Monitor. Working in partnership with Dr. Stefan Reimann from Empa, TOFWERK is currently operating…
Researchers from Dr. Zamin Kanji’s research group at ETH Zürich including Dr. Cuiqi Zhang and Dr. Michael Rösch have successfully installed and operated a fog monitor (Droplet Measurement Technologies; model FM-100) at the high-altitude research station Jungfraujoch (JFJ; 3580 m a.s.l., 46°33’ N, 7°59’ E), marking a major milestone in Switzerland’s contribution to…
On July 2 and 3 the ACTRIS-Switzerland consortium met for its 2025 annual meeting at the MeteoSwiss Aerological station in Payerne. As well as updates from all ACTRIS-Switzerland partners, this year’s meeting had a special focus on remote sensing and bioaerosols given the extensive facilities dedicated to these topics at…
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 weekend and stayed around for a few days: wildfire emissions…
Switzerland has been proudly welcomed as the newest member of ACTRIS ERIC at the recent General Assembly. Switzerland has been actively engaged in ACTRIS as a Permanent Observer, contributing high-quality atmospheric observations through its national facilities and scientific expertise. With its transition to a Member, Switzerland now participates fully in…
