Ice nucleating particle concentration measurements with the Portable Ice
Nucleation Experiment
https://data.eol.ucar.edu/dataset/646.003

Summary
Temperature-dependent INP (ice nuceating particle) concentration measurements
performed with the Karlsruhe Institute of Technology (KIT) Portable Ice
Nucleation Experiment (PINE), model PINE-1A, during the S2noCliME campaign.
PINE-1A was installed at the Storm Peak Laboratory in Steamboat Springs,
Colorado at one of the station's total aerosol inlets to measure the INP
concentration in the immersion freezing mode. Measurements were conducted
automated and continuously except periods when the Instrument needed
maintenance.
