Development of the new dynamic cloud chamber AIDA-2

The Centre for Cloud Ice Nucleation (CCIce) operated by the Karlsruhe Institute of Technology (KIT) collaborated with Bilfinger Noell GmbH.to develop  a new dynamic cloud chamber, AIDA-2.

The chamber has a unique and innovative engineering design in order to perform cloud simulation experiments at constant cooling rates of up to 10 K min-1 over a temperature range from 30°C to -55°C. The CCIce support has also been fundamental for the co-development of a new and innovative mobile instrument for atmospheric measurements of ice nucleating particle (INP) concentrations and laboratory studies of ice nucleation processes. This new instrument called PINE (Portable Ice Nucleation Experiment) is the first instrument of its kind for fully-automated long-term INP measurements at high sensitivity and time resolution. Prototype versions were successfully tested at CCIce, and a commercial version has been available on the market since 2019. .
