| Zusammenfassung |
| Surface measurements of aerosol and ice nuclei (IN) at a Central European
mountain site during an episode of dust transport from the Sahara are
presented. Ice nuclei were sampled by electrostatic precipitation on
silicon wafers and were analyzed in an isothermal static vapor diffusion
chamber. The transport of mineral dust is simulated by the Eulerian
regional dust model DREAM. Ice nuclei and mineral dust are significantly
correlated, in particular IN number concentration and aerosol surface
area. The ice nucleating characteristics of the aerosol as analyzed with
respect to temperature and supersaturation are similar during the dust
episode than during the course of the year. This suggests that dust may be
a main constituent of ice nucleating aerosols in Central Europe. |
