Centre for Reactive Trace Gases In Situ Measurements, Switzerland

CiGAS-CH is the Swiss node of the Topical Centre for Reactive Trace Gases In Situ Measurements (CiGas). CiGas offers state-of-the art operational support to ACTRIS National Facilities (NFs) and exploratory platforms, which are operating instrumentation for continuous long-term measurements of volatile organic compounds (VOCs), condensable vapours and nitrogen oxides (NOx) in the atmosphere.


Centre for Aerosol Remote Sensing, Switzerland

ACTRIS-Switzerland contributes to CARS through the World Optical Depth Research and Calibration Center (WORCC), which is a section within the World Radiation Center at the Physikalisch-Meteorologisches Observatorium Davos (PMOD/WRC).


Jungfraujoch National Facility

Aerosol measurements at the Jungfraujoch Observatory were first initiated by the Paul Scherrer Institute in 1988, and continuous aerosol monitoring has been performed since 1995. These continuous measurements are part of the Swiss contribution to the Global Atmosphere Watch (GAW) programme of the World Meteorological Organization, which is tightly linked to ACTRIS.

Swiss Midlands

Swiss Midland National Facility

The joint stations of Payerne and Berom√ľnster form the ACTRIS-Switzerland Swiss Midland Observatory. The continuous aerosol and trace gas measurements performed at these stations complement the equivalent measurements performed at the high altitude Jungfraujoch Observatory, particularly during the summer when convective activity regularly transports air from the Swiss Midlands up to Jungfraujoch.


PSI Atmospheric Chemistry Simulation Chambers (PACS)

The Atmospheric Chemistry Simulation Chambers at PSI (PACS) are an ACTRIS-Switzerland exploratory platform. These simulation chambers are laboratory facilities that can be used to perform different types of atmospheric chemistry under controlled conditions and in the presence of a comprehensive suite of instruments.
