polar stratospheric clouds
Abstract. An anomalous red glow due to scattered sunlight was observed at Longyearbyen (78 ◦ N, 15 ◦ E) on 6 December 2002 from 07:30 UT to 13:30 UT when the solar zenith angle varied between 100.7 ◦ and 104 ◦. A model for this red sky event using sunlight scattered in a two stage process by Polar S...

A model for this red sky event using sunlight scattered in a two stage process by Polar Stratospheric Clouds (PSC) at 25 km is presented and demonstrated to be feasible. The model requires a significant fraction of the polar vortex, which is cold enough for the formation of ice PSC, to be occupied with PSC with an integrated vertical extinction of approximately 0.037 at 845 nm. Given these conditions, the model is able to predict, within an order of magnitude, the spatial distribution of intensities measured by meridional scanning photometers located at Longyearbyen across the visible and near infra-red spectrum.
