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.

拉布拉多鹅湾的高频雷达最初是用来研究E和F区高纬度电离层电子密度不规则过程和高纬度对流的。最近很明显，雷达也可以用来研究与高频传输有关的问题，高频传输是在远距离从地面斜反射到达的。其中包括由传播重力波激发的电离层扰动（TID）。本研究计划研究这些高纬度重力波的激发和传播，以了解太阳风/磁层和热层之间能量耦合的一种形式。他们还建议开发和实现观测到的重力波事件的数据库。
