The HF radar at Goose Bay Labrador, was originally built and used to study processes relating to electron density irregularities in the E and F region high latitude ionospheres, and to study the high latitude convection. It has recently become apparent that the radar can also be used to study problems relating to HF transmission which arrive reflected obliquely from the ground at large distances. These include traveling ionospheric disturbances (TID's) which are excited by propagation gravity waves. This proposal plans to study the excitation and propagation of these high latitude gravity waves in order to understand one form of energy coupling between the solar wind/magnetosphere and thermosphere. They also propose to develop and achieve a data base of observed gravity wave events.

鹅湾拉布拉多（Goose Bay Labrador）的HF雷达最初是为了研究与电子和F区域高纬度电离层中电子密度不规则性有关的过程，并研究高纬度对流的过程。 最近显然，雷达也可以用于研究与HF传播有关的问题，与HF传播有关，后者在大距离上倾斜地反射。 其中包括通过传播重力波激发的旅行电离层干扰（TID）。 该建议计划研究这些高纬度重力波的激发和传播，以了解太阳风/磁层和热层之间的一种能量耦合。 他们还建议开发并实现观察到的重力波事件的数据库。
