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.


Contributing to ACTRIS with several exploratory platforms.
