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，国家科学基金会在拉布拉多的鹅湾进行了分阶段的阵列HF雷达资助。 该雷达由约翰·霍普金斯大学（Johns Hopkins University）应用物理实验室构建，以研究高纬度等离子体电离层的E和F区域中的形成电子密度不规则性，并研究高lage仪对流的落后尺度结构和动力学。 该赠款为研究时代和夜间电离层的对流响应的动力学提供了支持，以使星际磁场和太阳风变化。 要研究的其他项目包括振荡或瞬态磁层边界干扰产生的对流结构以及高纬度电离层不规则的形成。 该赠款的一部分将继续用于维持高纬度电离层的连续HF雷达观测值的数据库，该观察将为其他科学家使用。 ***
