| Summary: | Abstract. Polar stratospheric clouds (PSC) have been ob-served in early winter (December 2002) during the SOLVE II/Vintersol campaign, both from balloons carrying compre-hensive instrumentation for measurements of chemical com-position, size distributions, and optical properties of the par-ticles, as well as from individual backscatter soundings from Esrange and Sodankylä. The observations are unique in the sense that the PSC particles seem to have formed in the early winter under synoptic temperature conditions and not being influenced by mountain lee waves. A sequence of measure-ments during a 5-days period shows a gradual change be-tween liquid and solid type PSCs with the development of a well-known sandwich structure. It appears that all PSC observations show the presence of a background population of solid particles, occasionally mixed in with more optically |
