ASCOS was an interdisciplinary expedition to the central Arctic on the icebreaker Oden from 1 August to 9 September 2008. The expedition focused on processes relating to cloud formation in the summer Arctic and included observations of marine biology and chemistry, atmospheric chemistry, physical oceanography, aerosol chemistry and physics, and meteorology. This zip_file contains the half-hour ... consensus profile data from the 449 MHz wind profiler on the Oden during ASCOS. Version 1 contains netcdf files of the consensus half-hourly wind profile/signal-to-noise. It only contains data from the drift portion of the cruise (YD228-245; Aug. 15 ? Sep. 1). Data from the return cruise is available but have not yet been corrected for ship motion. The radar altitude was estimated at 10 m mean sea level, which should be added to the height data, which is given as above ground level (radar level).
