HF Radar Studies of the Geospace Plasma Environment

自1983年以来，美国国家科学基金会资助了在拉布拉多鹅湾的相控阵高频雷达的研究。该雷达由美国约翰霍普金斯大学应用物理实验室研制，用于研究高纬等离子体电离层E区和F区形成电子密度的不规则性以及高纬对流的大尺度结构和动力学。该基金为研究日、夜侧电离层对流对行星际磁场和太阳风变化的动态响应提供了支持。需要研究的其他项目包括振荡或瞬态磁层边界扰动引起的对流结构和高纬度电离层不规则结构的形成。这笔赠款的一部分将用于继续维持一个数据库，该数据库将向其他科学家提供高纬度电离层的连续高频雷达观测数据。＊＊＊

Since 1983, the National Science Foundation has funded research with a phased-array HF radar at Goose Bay, Labrador. This radar was constructed by The Johns Hopkins University Applied Physics Laboratory to study the formation electron density irregularities in the E and F regions of the high - latitude plasma ionosphere and to study the lagre-scale structure and dynamics of high-latitude convection. This grant provides support for studying the dynamics of the convection response in both the dayside and nightside ionosphere to changes in the interplanetary magnetic field and solar wind. Additional projects to be studied include convections structures resulting from oscillatory or transient magnetospheric boundary disturbances and the formation of high-latitude ionospheric irregularities. A portion of the grant will be used to continue to maintain a data base of continuous HF radar observations of the high-latitude ionosphere which will be available to other scientists. ***
