| Zusammenfassung |
Polar stratospheric clouds (PSCs) are often
observed in the Kiruna region in northern Sweden, east of the Scandinavian
mountain range, during wintertime. PSC occurrence can be detected by
ground-based optical instruments. Most of these require clear tropospheric
weather. By applying the zenith-sky colour index technique, which works under
most weather conditions, the data availability can be extended. The observations
suggest that PSC events, especially of type II (water PSCs) may indeed more
common than predicted by synoptic models, which is expected because of the
frequent presence of mountain-induced leewaves. However, it will be of
importance to increase the density of independent observations.
