Abstract

Wind profiles and acoustic backscatter from a Scintec Flat Array Sodar (MFAS) Sodar deployed on the sea ice during for the international Multidisciplinary drifting Observatory for the Study of Arctic Climate
(MOSAiC). Variables include vertical backscatter, intensity, mean wind speed and direction, wind components, and standard deviations of the wind variables - in the instrument reference frame - along with wind speed and direction in the earth frame, and quality control variables at 10 minute intervals. Also vertical backscatter only at 5 minute intervals.

The University of Leeds participation in the project- MOSAiC Boundary Layer -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). This was a year-long project on the German icebreaker Polarstern to study Arctic climate focused on measurements of atmospheric boundary layer dynamics and turbulent structure.
