Book Description
The ionospheric propagation of high-frequency radio waves is profoundly influenced by the variations of sunspot numbers and of geomagnetic activity. Thus, details of these variations, and of the relationship between them, has practical application. The variation of the geomagnetic activity index Ap over the 38-year interval January, 1932 through January, 1970 differs in several important characteristics from the variation of sunspot numbers over the same interval. A spectral analysis approach was used d to investigate this variation of AP, as well as its relation to the variation of sunspot numbers. The data analyzedconsisted of the 457 monthly average AP indices (AP) for the interval and the corresponding observed monthly sunspot numbers. Several large samples of the original daily Ap indices were also analyzed. Two of the latter samples covered 11-year intervals (April 1, 1944 - June 2, 1955; and June 1, 1956 - July 31, 1967) and the third covered a 23-year interval (April 1, 1944 - December, 1967).

Book Description
The latest attempt to summarize the wealth of knowledge now available on geomagnetic phenomena has resulted in this comprehensive multi-volume treatise, with original up-to-date review articles from many distinguished experts. The third volume of this series covers two broad topics--the relevance of the Eatrh's magnetic field for geological studies and the physics of the upper atmosphere.
