Ice nucleating particle concentrations measured by the KIT-PINE during the AGINSGP field experiment

Overview:

Real-time, immersion mode ambient ice nucleating particle (INP) concentrations were measured at ARM’s Southern Great Plains (SGP) site during the AGINSGP field experiment using a Portable Ice Nucleation Experiment (PINE) from Karlsruhe Institute of Technology (KIT). The KIT-PINE is a cloud expansion chamber that counts the number of INPs using an optical particle counter (Möhler et al. 2021). The instrument was located in the guest instrument facility (GIF) and measured INP concentrations from April 8th to April 29th.

Air was drawn into the GIF through custom aluminum stack inlets (6” inner diameter) attached vertically to the outer GIF wall and the GIF outside platform. A blower pulled air through the stacks at a velocity of 1 m/s. Aerosol instruments subsampled via wall ports, through either 3/8” or 1/4" copper lines, depending on sample flow of the instrument.
