A novel method for calibration and quantitative aerosol optical propertyretrieval from Doppler wind lidars (DWLs) is presented in this work. Due tothe strong wavelength dependence of the atmospheric molecular backscatterand the low sensitivity of the coherent DWLs to spectrally broad signals,calibration methods for aerosol lidars cannot be applied to coherent DWLsusually operating at wavelengths between 1.5 and 2 μm. Instead,concurrent measurements of an airborne DWL at 2 μm and the POLISground-based aerosol lidar at 532 nm are used in this work, in combinationwith sun photometer measurements, for the calibration and retrieval ofaerosol backscatter and extinction profiles at 532 nm.  The proposed method was applied to measurements from the SALTRACE experimentin June–July 2013, which aimed at quantifying the aerosol transport andchange in aerosol properties from the Sahara desert to the Caribbean. Theretrieved backscatter and extinction coefficient profiles from the airborneDWL are within 20 % of POLIS aerosol lidar and CALIPSO satellitemeasurements. Thus the proposed method extends the capabilities of coherentDWLs to measure profiles of the horizontal and vertical wind towards aerosolbackscatter and extinction profiles, which is of high benefit for aerosoltransport studies
