GEM: Determination of Response Time of Polar Ionospheric Convection Pattern to Changes in IMF During GEM Campaign Periods Using Ground-Based Radar and DMSP Satellite Data

PIS将结合四个月期间收集的地面雷达数据和DMSP卫星数据，研究全球反应时间。四颗在轨运行的DMSP卫星使卫星数据测量的反应时间分辨率高达几分钟。这项提议将分析雷达和卫星数据中看到的电离层响应，以确定响应时间作为MLT和位置的函数。结果应能更好地了解极地电离层对流模式在国际货币基金组织发生符号逆转后的演变。

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.***
