Title

Potential Role of Nuclei in Cloud Element Formation at High Altitudes

Abstract

The role of aerosols in providing a heterogeneous nucleation contribution to cirrus cloud ice crystal formation has long been an unresolved question. A mobile aerosol sampling facility was employed on the NCAR Sabreliner research aircraft to take aerosol samples from the vicinity of cirrus clouds over Colorado and Wyoming. Tandem electrostatic classifier and impactor technique were used to measure aerosol size distribution, hydration capability and composition information. The results suggest that aerosol related heterogeneous nucleation processes are active in cirrus cloud processes.
