Summary

While there is a considerable amount of experience with short-wave radio communication via the ionosphere from the many Antarctic expeditions beginning in 1911–12, quantitative determinations of ionospheric parameters exist for only a few places and for relatively short periods of time. From sweep-frequency vertical sounding observations at these few points on the Antarctic Continent and on surrounding islands, there is evidence of at least a rough north–south correspondence of F-region critical frequencies. The operation of a rather dense network of stations during IGY will be needed for any real description or understanding of these phenomena. The objectives of a number of analyses with data from the IGY period are mentioned.
