Available in PDF, EPUB and Kindle. Book excerpt: Annals of the International Geophysical Year, Volume 37: Whistlers and Audio-Frequency Emissions presents the principal results obtained in Whistlers-East synoptic program publications. Although whistlers can be observed at any time of day, it is found that they occur primarily at night. The greatest incidence of whistlers during the International Geophysical Year (IGY) period occurred in both hemispheres in the geomagnetic latitude range 50-60°. The day-to-day correlation of whistler activity at geomagnetically conjugate stations was sometimes very low and sometimes remarkably high. This book specifically provides data of monthly summaries of whistlers and audiofrequency emissions observed and recorded on magnetic tape at the given stations during the IGY (1957 Jul - 1958 Dec). The summaries have been compiled from daily tabulations obtained by aural reduction of the recordings. The IGY agreements required only that monthly summaries be sent to the World Data Centers but for some stations, daily tabulations were sent instead. For most stations the daily tabulations and the magnetic tape recordings themselves have been preserved and are held by the persons having supervision of each station and the aural reduction of data there from. This book will be of value to geophysicists and space scientists and researchers.

Download or read book Whistlers and Related Ionospheric Phenomena written by Robert A. Helliwell and published by Courier Corporation. This book was released on 2014-06-10 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: The investigation of whistlers and related phenomena is a key element in studies of very-low-frequency propagation, satellite communication, the outer ionosphere, and solar-terrestrial relationships. This comprehensive text presents a history of the study of the phenomena and includes all the elements necessary for the calculation of the characteristics of whistlers and whistler-mode signals. An introduction and brief history are followed by a summary of the theory of whistlers and a detailed explanation of the calculation of their characteristics. Succeeding chapters offer a complete atlas of a variety of whistlers, including those observed in satellites and those generated by nuclear explosions; the results of satellite observation of whistler-mode propagation; the method of reducing whistler data and obtaining electron density information; a full atlas of the various kinds of emissions; and an outline and comparison of the theories of generation of emissions.

Book excerpt: Amplitude analysis of discrete VLF emissions using the Rayspan spectrum analyzer showed characteristics that are not readily detected using the conventional 'frequency' spectrograms. From a small sampling of discrete VLF emissions recorded at various ground stations, the following observations were made: Rise and fall times may be as small as 15 - 20 msec; Emissions that appear 'single' on a frequency spectrogram may consist of closely-linked shorter emissions, each having a duration of the order of 100 msec; Frequency modulation, previously suspected in some frequency spectrograms, is confirmed. In the samples studied the frequency of modulation ranged from 35 Hz to 70 Hz, while the frequency deviation lay mainly in the range 25 Hz to 50 Hz. (Author).

Download or read book The Radio Noise Spectrum written by Donald Howard Menzel and published by Harvard University Press. This book was released on 1960 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: This modern era has had many names: the golden age, the machine age, the atomic age, the electronic age, and so on. One further title, hitherto unpublicized, it eminently deserves: the age of noise. Man has compounded the natural noise that preceded his existence on the earth until no point on this globe is free from it. Even in the desert's hush, radio waves pervade the air and provide a source of potential noise. The shorter waves escape from the earth and fill interplanetary space with the mingled clamor of FM, TV, radar, and other insistent voices. This book deals with the important problem of radio noise, its sources, whether manmade or natural, over the known range of frequencies. Certain of these contributions will interest the communicator, enabling him to estimate the potential interference from various types of sources. Other contributions deal mainly with scientific problems, such as the origins and significance of certain characteristic noise radiations. The contributors to this book are experts on the various phases of radio noise. The individual chapters derive from papers presented at a Conference on Radio Noise, held at Harvard College Observatory, April 22, 1958.
