Download or read book Global Morphology of Ionospheric Scintillations written by Jules Aarons and published by . This book was released on 1970 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Amplitude fluctuations produced by small irregularities in electron density in the F-layer of the ionosphere (at 300 to 400 km height) can be a problem to communication and navigation systems in the VHF-UHF range. Recent measurements, primarily by AFCRL, are shown with emphasis on results at high and equatorial latitudes. At high latitudes an irregularity region exists whose lower boundary reaches 57 degrees invariant latitude near midnight. During magnetic storms the boundary descends to lower latitudes and the fading becomes deeper. Over the polar cap scintillations are somewhat diminished. When observing synchronous satellites through the irregularity region, deep and fast fading is frequently seen, with fade rates to one per second. Irregularities produce deep scintillations in the VHF range plus or minus 15 degrees from the geomagnetic equator. In equatorial regions maximum occurrence of high level scintillations takes place between 2100 and 2400 local time during the equinoxes; a minimum occurrence is observed during the solstices. When the sunspot number decreases, the equatorial irregularity region spreads and becomes larger. The data for various latitudes has been placed in statistical form, that is, distribution of amplitudes for 15-min samples as well as for periods of 1 yr and longer. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The transition or boundary between high- and low-amplitude ionospheric fluctuations has been examined as a function of time. The boundary of the scintillation curtain reaches its lowest latitude (54 degrees geomagnetic north) between 1930 and 2230 local time. The most northerly boundary latitude of approximately 80 degrees Gn occurs during the 1030 to 1330 local standard time period. General agreement is demonstrated between observations of Transit IVA at 54 MHz at a subauroral site, Explorer 22 (S-66) at 40 MHz at three sites, and the main zone of discrete auroral events shown by other workers.
