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.
