Aerosol backscatter and along-beam Doppler velocities from a HALO Doppler lidar on board the German icebreaker Polarstern ship for the Multidisciplinary drifting Observatory for Study of Arctic Climate (MOSAIC) project.

The University of Leeds participation in MOSAiC was funded by the Natural Environment Research Council (NERC, grant: NE/S002472/1) and involved instrumentation from the Atmospheric Measurement and Observations Facility of the UK's National Centre for Atmospheric Science (NCAS AMOF).
