Abstract:
Wind lidar measurements of the atmospheric boundary layer (ABL) were performed during the Multidisciplinary drifting Observatory for Study of Arctic Climate (MOSAiC) from September 2019 to October 2020. A "Halo-Photonics Streamline" (HPS) scanning wind lidar was used, which operates at a wavelength of 1.5 μm. The lidar can operate with a maximum range of 10km and is a programmable scanner, which enables vertical scans in all hemispheric directions. Vertical azimuth display (VAD) scan patterns were used for the determination of wind profiles above the lidar. The Doppler velocities were corrected for lidar orientation (pitch/roll/heading) and the ship speed, and different quality checks were performed (see Zentek et al. 2018). VAD scans were performed for the months of September and October 2019 and for March to September 2020 with major data gaps for 14 Feb. 2020 - 17 March 2020 and for 25 March 2020 - 28 March 2020. Wind profiles were measured also during the transfer periods of Polarstern between different drift phases. The profiles have a temporal resolution of about 10 min and a spatial resolution of 30m in the vertical. Heights are above sea level.
