Aerosol samples were lognormally distributed with a mode diameter of 0.4(+/- 0.1) mu m and geometric standard deviation of similar to 1.7(+/- 0.2). At temperatures warmer than -40 degrees C droplets were formed before ice crystals formed and there was generally no deposition nucleation observed. At temperatures colder than -40 degrees C both dust samples exhibited dual nucleation events that were observed during the same expansion experiment. The primary nucleation event occurred at ice saturation ratios of 1.1 to 1.3 and is likely to be a deposition nucleation mode. The secondary nucleation event occurred at ice saturation ratios between 1.35 and 1.5. We cannot categorically determine whether this ice nucleation event is via a further deposition mode or a condensation mode, but the presence of some soluble material in the dust samples leads us to favour the latter process. The activated fractions of desert dust ranged from similar to 5-10% at -20 degrees C to 20-40% at temperatures colder than -40 degrees C. There was no obvious difference between the nucleation behaviour of the two dust samples. 000059801 536__ $$0G:(DE-Juel1)FUEK406$$2G:(DE-HGF)$$aAtmosphäre und Klima$$cP22$$x0 000059801 588__ $$aDataset connected to Web of Science 000059801 650_7 $$2WoSType$$aJ 000059801 7001_ $$0P:(DE-HGF)0$$aMöhler, O.$$b1 000059801 7001_ $$0P:(DE-HGF)0$$aConnolly, P.$$b2 000059801 7001_ $$0P:(DE-Juel1)129131$$aKrämer, M.$$b3$$uFZJ 000059801 7001_ $$0P:(DE-HGF)0$$aCotton, R.$$b4 000059801 7001_ $$0P:(DE-HGF)0$$aHeymsfield, A.
