Comparison observations between the MU radar and the Kyoto meteor radar

We have performed a comparison between the MU radar and the Kyoto meteor radar on August 14-15, 1984. The MU radar provided vertical, zonal and meridional wind components in the 65- to 85-km region during daylight hours when echoes from the turbulent scattering were intense. Meteor echoes were also received by the MU radar, and utilized to measure winds at meteor heights. Comparisons among these MU radar measurements and Kyoto meteor radar observations have shown fairly consistent wind profiles at 65- to 105-km altitudes. To interpret differences in the wind fields observed in 2 successive days, it was necessary to consider the behavior of quasi 2-day oscillation deduced from long-duration Kyoto meteor radar observations.
