The interpretation of ionospheric radio drift measurements—VIII. Direct comparisons of meteor radar winds and Kinesonde measurements: mean and random motions

摘要: We present a detailed comparison between meteor wind measurements by the Garchy-Sens Beaujeu radar and ‘Kinesonde’ spaced-antenna drifts, jointly conducted during January–April 1970. Statistical conclusions result from total of 39 instances in each which sufficient sample (10–25 meteors) is centered height (± 2 km) time 60 min) on estimated location Kinesonde measurement. Each case yields estimates mean eastward Ux, standard deviation σx, error estimate Ux. Through correlation analysis spaced-antenna, spaced-frequency echo fading, yield velocity vector V(x, y, z) ‘velocity correloid’ Vc(x, z), latter measure scale random velocity. find significant agreement Ux Vx, (Vc)x, with coefficients 0.912 0.588. The scales motion probably responsible for this are examined.
