This paper presents results from a five and half-year study (2015-2020) at an ACTRIS station located in Măgurele, Romania focusing on lidar calibration and assessment of correction factors to improve data accuracy from a multiwavelength Raman polarization lidar operating since 2008. The lidar system was used to measure atmospheric aerosols. Regular quality assurance tests were performed, and all datasets were processed with the Single Calculus Chain software. The analysis revealed that the lower troposphere had more fine particles than the upper troposphere, and the highest Ångström exponent values were reached in autumn and summer. With a careful calibration, lidar technology can be used for determining the aerosol optical and microphysical parameters at the quality necessary for accurate radiation calculations and for the prediction of aerosol–climate effects..
