Ice Nucleation Experiment No. 07 (IN07)
KIT (AIDA), October 2005
The ice formation rates on untreated mineral dust aerosol particles and on the same particles coated with sulphuric acid or secondary organic aerosol mass were compared to each other in subsequent cloud simulation experiment in the AIDA (Aerosol Interaction and Dynamics in the Atmosphere) cloud chamber of Forschungszentrum Karlsruhe (now KIT). Arizona test dust was used as a reference material for these studies. During these experiments the AIDA facility was equipped with a comprehensive instrumentation for aerosol, ice nuclei, and ice particle characterisation. We operated the Quadrupole Aerosol Mass Spectrometer (Q-AMS).
