Short summary
Stratospheric particles were collected in the polar stratosphere in winter 1999/2000. Besides the well-studied volatile particles from that region, the main findings of this study are stable carbonaceous particles in the sub-micrometer size range. In addition to carbon, many particles show the elements Si, Fe, Cr and Ni to a minor amount. Based on exclusion, carbonaceous material from IDPs and residues from meteoric ablation and fragmentation remain as the most probable sources.
