| Zusammenfassung |
| This paper reports on backscatter and depolarization measurements by
an airborne lidar in the Arctic during the ASTAR 2004 campaign. A
unique weather situation facilitated the observation of the aerosol
concentration under strongly forced atmospheric conditions. The
vigorous easterly winds distorted the flow past Svalbard in such
a way that mesoscale features were visible in the remote-sensing
observations: The formation of a well-mixed aerosol layer inside the
Adventdalen and the subsequent thinning of the aerosol plume were observed over
the Isfjorden. Additionally, mobilization of sea salt aerosols
due to a coastal low-level jet at the northern tip of Svalbard resulted in a
sloped boundary layer toward north. Mesoscale numerical modelling was
applied to identify the sources of the aerosol particles and to explain
the observed patterns. |
