Formation of solid particles in synoptic-scale Arctic PSCs in early winter 2002/2003
International audience Polar stratospheric clouds (PSC) have been observed in early winter (December 2002) during the SOLVE II/Vintresol campaign, both from balloons carrying comprehensive instrumentation for measurements of chemical composition, size distributions, and optical properties of the par...

International audience Polar stratospheric clouds (PSC) have been observed in early winter (December 2002) during the SOLVE II/Vintresol campaign, both from balloons carrying comprehensive instrumentation for measurements of chemical composition, size distributions, and optical properties of the particles, 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 measurements during a 5-days period shows a gradual change between liquid and solid type PSCs with the development of a well-known sandwich structure.
