After correction of the sonic orientations using the sonic boom angles measured with the Data Scope, there were still systematic differences in the sonic wind directions across the arrays that were broadly correlated with the post-project sonic zero wind offsets measured in the wind tunnel. Therefore we subtracted offset corrections from the sonic horizontal wind components u and v.
