Mapping the Wind in the Polar Thermosphere: A Case Study within the CEDAR (Coupling, Energetics and Dynamics of Atmospheric Regions) Program

摘要

The purpose of this paper is to present one part of the CEDAR program which illustrates the power of the combination of full vector wind data from several data sites in the northern arctic. A special, internationally coordinated campaign was organized for the 4-day period January 14-17, 1986. This campaign had a global distribution of 22 possible optical stations and six possible radars specially organized to participate covering both hemispheres. Ionosonde stations were also alerted to the existence of the special period. This paper concentrates on the dynamics of the high-latitude regions using the optical wind data and the radar ion drifts to study the situation.
