Book Description
An intensive study of nighttime electron density irregularities in the equatorial ionosphere was conducted in October 1976 by making simultaneous radar and scintillation measurements near the magnetic dip equator. The 50-MHz radar observations at Jicamarca, Peru, and scintillation measurements at nearby ground stations of Ancon and Huancayo, Peru, were made by receiving VHF transmissions from the geostationary satellites, LES-9 and Marisat, as well as the VHF transmissions from the orbiting Wideband satellite. The thick irregularity patches detected by the radar could be associated with intense scintillation events, signifying thereby that the patches containing 3-m irregularities also contain kilometer-sized irregularities, giving rise to the radar backscatter and scintillations, respectively. By comparison of the onset times of scintillation on different propagation paths separated in the east-west direction, as well as by performance of spaced receiver scintillation measurements at Ancon, the drift speed of irregularities was determined. The irregularities were observed to drift eastwards at a speed ranging between 90 and 140 m per sec during 1900 and 2400 local time. From a knowledge of the derived value of drift speed and the duration of scintillation events, the irregularity patches were found to have eastward dimensions between 100 and 800 kilometers. On a statistical basis, the irregularity patches detected in the scintillation experiment were noted to be preponderant to those giving rise to thick radar backscatter structures. This indicates the possiblity of having equatorial irregularity patches with spectral powers concentrated at large scale sizes only. (Author).

Book Description
Low Latitude Aeronomical Processes contains the papers presented at the symposium on Low Latitude Aeronomical Processes, held in Bangalore, India in May and June 1979. The conference focuses on the discussion and exchange of scientific studies on low latitude aeronomy, of which India is one of the main practitioners. The presentations contained in the book cover areas of study in equatorial electrojet, electric field, and electric current; low latitude middle atmosphere; and low latitude ionosphere above 100 km. Trans-ionospheric propagation in the equatorial regions and stratospheric chemistry and sun-weather relationships for low latitude regions, as well as a discussion on incoherent and coherent scatter observations at low latitude, are encompassed as well. Atmospheric physicists and researchers will find this book an interesting read.

Book Description
This is a compilation of seventeen (17) papers presented by the Space Physics Division at the 1978 Symposium on the Effect of the Ionosphere on Space and Terrestrial Systems. The symposium was jointly sponsored by the Naval Research Laboratory and the Office of Naval Research, January 24-26, 1978. The emphasis is on the occurrence of ionospheric irregularities and their effect on communication, radar and navigation systems.
