    Aerosol partitioning in natural mixed‐phase clouds
    (Wiley, 16.03.2004) Henning, Silvia; Bojinski, Stephan; Diehl, Karoline; Ghan, Steven; Nyeki, Stephan; Weingartner, Ernest; Wurzler, Sabine; Baltensperger, Urs
    In situ aerosol and cloud drop microphysical measurements at a high-alpine site are used to investigate aerosol partitioning between cloud and interstitial phases in natural, mid-latitude, mixed-phase clouds. Measurements indicate a decrease in the activated aerosol fraction (FN) for particle diameters dP > 100 nm with cloud temperature from FN ~ 0.54 in summer liquid-phase clouds to FN ~ 0.08 in winter mixed-phase clouds. The latter may be attributed to the Bergeron-Findeisen mechanism whereby ice crystals grow at the expense of liquid water drops, releasing formerly activated aerosols back into the interstitial phase. This provides a means to distinguish the indirect effects of aerosols on drops and ice crystals.
