Abstract:

This work presents observations of the aerosol mixed layer in the planetary boundary layer and aerosol layers in the lower troposphere during a case of winter Bise wind. The Bise wind event occurred from December 5 till December 18, 2001. The observations were performed above Neuchâtel, Switzerland, 47.00°N, 6.95°E, 488 m asl, using a ground-based backscatter lidar, operating at a wavelength of 532 nm. The height of the aerosol mixed layer was found to extend up to 0.6–0.8 km agl. Another aerosol layer centred around 1.5 km and 2.5 km agl was also observed. The combination of the lidar-observed profiles with radiosonde measurements from Payerne station shows a coincidence of the altitudes of the observed aerosol layers with the altitudes of the Bise wind layer. Back trajectories were used to trace the incoming Bise air masses showing a likely origin from North America.

Diese Studie präsentiert Beobachtungen von Aerosolen in der planetaren Grenzschicht und in der freien Troposphäre während Bise-Bedingungen. Das diskutierte Bise-Ereignis fand in der Periode vom 5.–18. Dezember 2001 statt. Die Aerosol-Beobachtungen wurden mit einem bodengestützten Rückstreulidar bei einer Wellenlänge von 532 nm in Neuchâtel, Schweiz (47,00°N, 6,95°E, 488 m über NN), gemacht. Die Höhe der Mischungsschicht, abgeleitet aus den Aerosolbeobachtungen, betrug etwa 0,6–0,8 km über NN. Eine weitere Aerosolschicht wurde zwischen 1,5 und 2,5 km über Grund beobachtet. Der Vergleich der Lidar-Profile mit Radiosondenmessungen aus Payerne belegt, dass die Höhe der Aerosolschichten mit der Höhe der Bise-Winde übereinstimmt. Rückwärtstrajektorien zeigen, dass die Aerosole in den Bise-Luftmassen ihren Ursprung vermutlich in Nordamerika gehabt haben.
