The definition of the fit deviation, the main processing of the lidar data and an evaluation of the measurements is described in Zentek et al. (2018; doi:10.5194/amt-11-5781-2018 ). For this data set winds were computed every 50 m up to 1000 m and the data is averaged over time. The averaging time is one hour (+-30min around each full hour) and missing values are removed. A weighted arithmetic mean was used for the u- and v-component as well as for the fit deviation with the weights "1/fit deviation". The backscatter coefficient was averaged without weights. As backscatter was always measured, hours were included even if no wind could be computed due to atmospheric conditions but hours with no reliable data were excluded (e.g. the lidar was turned off; the ship was rocking to hard; etc.). Further detailed information for this measurement campaign: number of rays per VAD [6-8], averaging time [3-8 sec], chosen SNR threshold [-19 dB].The measurements were performed during the Polarstern cruise PS109 funded by the Alfred Wegener Institute under Polarstern grants AWI_PS109_12. The research was funded by the Federal Ministry of Education and Research (Bundesministerium für Bildung und Forschung–BMBF) as part of the project CATS ("The Changing Arctic Transpolar System") under grant 03F0776D.-19.77924-5.8896876.1468980.46152Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research, Bremerhavenhttps://doi.org/10.13039/501100003207AWI_PS109_12Federal Ministry of Education and Researchhttps://doi.org/10.13039/50110000234703F0776DDas arktische transpolare System im Wandel; Vorhaben: Veränderungen der Atmosphäre-Meereis-Ozean Interaktionen und deren Einfluß auf das transpolare System (TP 2)
