The Development of Radio Traffic Frequency Prediction Techniques for Use at High Latitudes

A brief historical review is presented of ionospheric work leading to the development of radio prediction techniques in order to provide a background and to emphasize the fact that all prediction methods are relatively quite "young." A bibliography of Canadian work is given. The merits and defects of some prediction techniques are discussed with particular attention to the Canadian problem in the far north. The results of recent research are shown to hold promise in the field of predictions. The paper concludes with some speculation on possible trends in both long- and short-term prediction methods.
