During the one-year MOSAiC expedition the multiwavelength polarization Raman lidar Polly (POrtabLe Lidar sYstem) (Engelmann et al., 2016, 2021) was continuously operated aboard Polarstern. Automated measurements of aerosol and cloud profiles up to stratospheric heights were collected from 26 September 2019 to 2 October 2020. The Polly instrument is mounted inside the OCEANET-Atmosphere container of the Leibniz Institute for Tropospheric Research (TROPOS). Data are manually analyzed height profiles of particle backscatter coefficient, particle extinction coefficient, particle linear depolarization ratio, extinction-to-backscatter ratio, and Anstrom exponents at 355 nm, 532 nm, and 1064 nm wavelengths.
