Haarig, Moritz; Althausen, Dietrich; Ansmann, Albert; Klepel, Andre; Baars, Holger; Engelmann, Ronny; Groß, Silke; Freudenthaler, Volker (2016): Measurement of the linear depolarization ratio of aged dust of three wavelengths (355, 532 and 1064 nm) simultaneously over Barbados. In: EPJ Web of Conferences, Vol. 119, 18009


A ground-based polarization Raman lidar is presented, that is able to measure the depolarization ratio at three wavelengths (355, 532 and 1064 nm) simultaneously. This new feature is implemented for the first time in a Raman lidar. It provides a full dataset of 3 backscatter coefficients, two extinction coefficients and 3 depolarization ratios (3+2+3 lidar system). To ensure the data quality, it has been compared to the well characterized two wavelength polarization lidar POLIS. Measurements of long-range transported dust have been performed in the framework of the Saharan Aerosol Long-Range Transport and Aerosol-Cloud-Interaction Experiment (SALTRACE) in the Caribbean.
