They will have at least three and a half more years, though, to gather good data on upperatmospheric dynamics.
不过，他们至少还有三年半的时间收集上层大气动力的有效数据。

The Sondrestrom UpperAtmospheric Research Facility has a 32-metre-wide radar dish. It measures conductivity from an altitude of 60km to600km and has helped define the cusp's circuitry.
桑德日斯多姆高层大气科学研究所（Sondrestrom Upper Atmospheric Research Facility）拥有一个32米宽的雷达抛物面天线反射镜（radar dish），它可以检测到从海拔60公里至600公里的传导性并有助于详细说明尖端的电路结构。
