First ACTRIS intercomparison campaign of ice nucleating particle instruments conducted at the Jungfraujoch

Forschungsstation Jungfraujoch

In July and August 2023, two online ice nucleating particle (INP) instruments were running in parallel at the Jungfraujoch Research Station. This intercomparison exercise was an important step towards Jungfraujoch becoming a National Facility of the ACTRIS Topical Center for Cloud In Situ (CIS) Measurements. CIS aims to establish a European network for long-term measurements of INPs, an important variable for the weather and climate systems.
