Abstract Project: AWIPEV_0009

Christoph Ritter (AWI)

A Raman-lidar, operating at 3 different wavelengths is used to analyse tropospheric and stratospheric aerosol occurrences, particle properties, as well as water vapour in the lower troposphere and thin cirrus clouds. Using the wavelengths dependence of scattering the size distribution and refractive index of aerosol should be determined. For cirrus clouds their occurrence, lidar ratio and depolarisation as function of temperature, altitude and humidity (comparison with radiosonde) shall be analysed. The measurements shall take place continuously during all seasons. This is a long-term project to monitor trends.
