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 file contains moment data from S-band cloud/precipitation radar on the Oden during ASCOS. Version 1 contains netcdf files of the ~ 2 minute moment data (equivalent radar reflectivity, Doppler vertical velocity, Doppler spectral width) for the vertically pointing radar beam. Version 1 contains data from the drift portion of the cruise (YD214-260; Aug. 1 ? Sep. 16), which includes the return portion of the cruise over the Norwegian Sea as well. When the signal was below the minimum detectable signal for the radar, the reflectivity data were assigned a flag of ?-99.99,? and the velocity data were assigned a flag of ?99.99.?
