The PIs will combine ground-based radar data with DMSP satellite data collected during a four-month period to study global response times. The four operational DMSP satellites in orbit allow resolution of the response time measured by the satellite data to be as good as a few minutes. This proposal will analyze the ionospheric response seen in the radar and satellite data to determine the response time as a function of MLT and location. Results should give a better understanding of the evolution of the convection pattern in the polar ionosphere after a sign reversal in the IMF.***

PI 将结合地面雷达数据与四个月期间收集的 DMSP 卫星数据来研究全球响应时间。 在轨运行的四颗 DMSP 卫星可以使卫星数据测量的响应时间分辨率达到几分钟。 该提案将分析雷达和卫星数据中的电离层响应，以确定响应时间作为 MLT 和位置的函数。 结果应该可以更好地理解 IMF 符号反转后极地电离层对流模式的演变。***
