Lidar Measurements for Aerosol Remote Sensing — •Matthias Wiegner, Volker Freudenthaler, Birgit Heese, and Meinhard Seefeldner — Meteorologisches Institut München, Theresienstr. 37, 80333 München

Aerosol particles scatter and absorb radiation, influence air chemistry and the hydrological cycle. To understand these processes and their feedbacks with climate, measurements with high spatial and temporal resolution are required. The only means to obtain range resolved aerosol information is lidar remote sensing.

The Meteorological Institute Munich operates two very flexible lidarsystems: The first system (MULIS) is a mobile, scanning, three wavelength backscatter lidar, presently upgraded with two Raman and one depolarization channel. MULIS was part of several field campaigns for the determination of vertical profiles of the extinction coefficient, and member of the European Aerosol Lidar Network EARLINET where it was used as reference system for quality assurance. The second system (POLIS) is a portable two channel lidar, which can be used either in a Raman, depolarization or dual wavelength configuration. POLIS can be operated from a van as well as from an aircraft as demonstrated during the field campaign BBC2.

During the conference a demonstration of the capabilities of the lidars is planned.
