Abstract: Observations of upper mesospheric and lower thermospheric wind velocities obtained simultaneously over six days with MF Doppler and Spaced Antenna (SA) radars at Adelaide, Australia in November 1980 are presented. To obtain these measurements, the large (~ 1 km diameter) Buckland Park MF array was run in a dual beam Doppler radar configuration, and a portable SA radar was operated adjacent to the main array. Hourly mean values of wind velocity show considerable consistency, with cross correlation coefficients of about 0.6–0.8 for the entire observational period. However, agreement between the magnitudes of the wind velocities as measured by each technique is found to be significantly improved when the effect of the aspect sensitivity of the backscattering irregularities on the effective beam pointing angle of the Doppler radar beams is taken into account. This is also found to be true for SA and Doppler radar observations obtained in adjacent periods of 2–5 days over two years with the Buckland Park facility operating alternatively as a Doppler and SA radar. Some representative examples of these results are also presented and discussed. A preliminary comparison between MF Doppler and SA radar derived vertical wind velocities is also briefly considered.
