The backscatter lidar at the Esrange (68N, 21E) in northern Sweden measures altitude profiles of the aerosol load and depolarization in the stratosphere on a wavelength of 532 nm since winter 1996/97. During this winter 2000/2001 the lidar was upgraded to operate on three wavelengths, namely 355 nm, 532 nm, and 1064 nm. It is now possible to estimate in addition the size and shape distributions of the aerosols. During the last winter-campaign at the Esrange this new feature was tested: three-colour data could be obtained on six measurement days. On January 15, 2001, we observed an unusual, geometrically thick PSC extending from 21 km to 27 km altitude. This PSC showed at times very strong backscatter ratios of up to R = 3200 in the perpendicular polarized channel. During a 13.5 h long measurement run three colour measurements of PSC could be obtained. During the observation the opptical properties of the PSC changed dramatically: The backscatter ratios decreased by a factor of ten and the depolarization value by a factor of six. This can be attributed to a dynamical change in the atmosphere during the measurement time, recognizable in the wave-structure in the temperature-profile.
