Abstract
This paper presents an algorithm for calculating wind profiles from profiler Doppler spectra. Our algorithm produces hourly averaged winds by consensus averaging of the spectral peak power densities. The peak power method, applied separately on each height and on each antenna beam, can detect the atmospheric echo in each spectrum which results in the calculation of radial velocities in all antenna beams. The consensus algorithm is then applied to average over one-hour intervals using 12 radial velocities over each hour. A resultant 24-hour profile of horizontal winds is given to illustrate the effectiveness of the algorithm.
