Short summary

Several instruments can investigate properties of ice-nucleating particles (INPs), which are crucial to understanding ice cloud formation. We intercompare four online ice nucleation counters and reasonable agreement is found when the same ice nucleation mode is tested. A variable scaling factor was necessary to reconcile condensation freezing results with immersion freezing. Factors related to instrumental setup and aerosol generation are discussed to explain observed differences.
