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. ***

自1983年以来，国家科学基金会一直资助拉布拉多鹅湾相控阵高频雷达的研究。这台雷达是由约翰霍普金斯大学应用物理实验室建造的，目的是研究高纬等离子体电离层E区和F区的形成电子密度不规则性，并研究高纬对流的滞后尺度结构和动力学。这笔赠款为研究日侧电离层和夜间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助。有待研究的其他项目包括磁层边界振荡或瞬变扰动引起的对流结构以及高纬度电离层不规则的形成。赠款的一部分将用于继续维持高纬度电离层高频雷达连续观测的数据库，供其他科学家使用。***
