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…
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 from permanent observer to full member status at the next…
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 instrument of utmost importance will profile cloud structure with high…
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 by naneos particle solutions GmbH, a Swiss based company. Two…
The ACTRIS-Switzerland consortium met at PMOD/WRC this week for its annual meeting. The consortium was greeted at the institute in Davos with lovely weather, views, and hospitality. The day consisted of presentations detailing our latest scientific results as well as a discussion session for planning and coordinating our collaborative activities.…
