Facility
The Center for Cloud Ice Nucleation (CCIce) is situated at the Karlsruhe Institute of Technology (KIT) and is hosted by the Institute of Meteorology and Climate Research - Department Atmospheric Aerosol Research (IMK-AAF). Here, the large atmospheric simulation chamber AIDA (Aerosol Interaction and Dynamics in the Atmosphere) is employed for cloud studies, instrument inter-comparison or calibration. Atmospheric online-measurements are realized via PM10 inlets installed at the institute’s roof top. The department’s building also houses a chemical laboratory, a workshop and generous lab-space.
For calibration and inter-comparisons of ice nucleating particle (INP) online-instrumentation, CCIce uses a dedicated mobile cloud chamber, the Portable Ice Nucleation Chamber PINE. Offline-derived INP immersion freezing spectra are measured using the Ice Nucleation Spectrometer of the Karlsruhe Insitute of Technology INSEKT freezing assay. A dedicated cloud chamber for INP instrument calibration and inter-comparison will be available soon.
CCIce is currently being set-up and will be fully operational in 2026. The infrastructure implementation is funded by the German Federal Ministry of Education and Research (BMBF) within the ACTRIS-D project in the course of the strategy „Forschung für Nachhaltigkeit" (FONA).
