Positive Ion Composition Measurements in the Lower Ionosphere During the 12 November 1966 Solar Eclipse
Author: Rocco S. Narcisi
Publisher:
ISBN:
Category : Cations
Languages : en
Pages : 22
Book Description
Positive ion composition measurements in the D and E regions were performed on three rocket flights during the 1966 solar eclipse program conducted at Cassino, Brazil. The E region results showed that, at totality, NO+ and O2+ decreased in density while the ratio NO+/O2 increased. Long-lived meteoric ions appeared to be unaffected during the short period of the eclipse. A submerged layer of meteoric ions became prominent at totality when the molecular ion densities were smallest and produced a sporadic E layer. The D region results indicated that the decay in the water cluster ions at totality was probably less than a factor of four in the vicinity of 80 km. This work represents part of a continuing Air Force program to study lower ionospheric processes which affect communications. (Author).

Low Frequency Waves and Turbulence in Magnetized Laboratory Plasmas and in the Ionosphere
Author: Hans Pécseli
Publisher:
ISBN: 9780750312530
Category : SCIENCE
Languages : en
Pages : 0
Book Description
"Low Frequency Waves and Turbulence in Magnetized Laboratory Plasmas and in the Ionosphere was developed from courses taught by the author at the universities of Oslo and Tromso in Norway. Suitable for undergraduates, graduate students and researchers, the first part of the book is devoted to discussing some relevant plasma instabilities and the free energy that drives them. In the second part, the more advanced topics of nonlinear models and the interactions of many modes are discussed. Theoretical tools available for turbulence modelling are also outlined. The book summarizes a number of studies of low-frequency plasma waves, drift waves in particular, from laboratory and space experiments."--Prové de l'editor.

VLF/LF Reflection Properties of the Low Latitude Ionosphere
Author: Wayne I. Klemetti
Publisher:
ISBN:
Category : Ionospheric electron density
Languages : en
Pages : 106
Book Description
Low latitude observations of VLF/LF pulse reflections from the lower ionosphere obtained at nine locations to the east and west of a transmitter in southeastern Brazil are described. The data provide a variety of information on the reflection properties of the ionosphere below about 90 km altitude. Aspects of the data are presented in quasi-dimensional formats useful for identifying ionosphere structure and variability, and detailed analyses of portions of the data provided, which characterize the effective heights of the reflection coefficients of the ionosphere at noon and midnight, over a frequency range from 15 to 65 kHz. Electron density models of the ionosphere, derived from VLF/LF reflection data are also discussed. Keywords: VLF propagation; LF Propagation; Ionosphere reflectivity d region.
