This book was released on 1970 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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).

Download or read book Structure and Composition Measurements in Equatorial Ionospheric Bubbles written by R. Narcisi and published by . This book was released on 1980 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two multi-instrumented Terrier Malemute rockets including ion mass spectrometers were launched from Kwajalein on the nights of 17 and 23 July 1979 during equatorial Spread F events. Detailed ionospheric structure and composition measurements were made between about 100 and 590 km. The first flight penetrated six areas of 'bite-outs' spread over the range 265 to 560 km on upleg as well as several more depletions on downleg. The strongest irregularities, up to 90 percent depletion, occurred at the altitudes of 265 to 285 km just above the F region ledge at 250 km. There was no evidence of enhanced bottomside tracer ions (NO(+), O2(+) or meteoric ions) in any of the holes, which were composed mostly of O(+) and smaller amounts of N(+). From the composition signatures, the source of the bubbles appeared to be near the F region ledge. Within the higher altitude holes, the N(+)/O(+) ratios were smaller than the adjacent ionosphere ratios, indicating not only that the source regions were near the ledge, but also that the bubbles had initiated earlier when the ledge was at higher altitudes. While O(+) and N(+) exhibited strong fluctuations, NO(+) and O2(+) had fairly smooth profiles with scale heights similar to N2 and O2 respectively, demonstrating steady-state conditions and a stable neutral atmosphere with an exospheric temperature of about 1100K. This suggests that neutral atmospheric turbulence is not a major source of the ionospheric irregularities. Time periods for ion-chemical processes to achieve the observed composition are discussed in terms of bubble formation times and rise velocities.

Available in PDF, EPUB and Kindle. Book excerpt: Positive ion composition measurements obtained with rocket-borne mass spectrometers in the lower ionosphere are presented. The current situation regarding the water cluster ions in the D region is considered. Evidence is given in favor of an ambient instead of a contamination origin for the water cluster ions, although the exact processes for the formation of these ions in the atmosphere are still not definitely established. A theory is discussed whereby water cluster ions may be created through the ionization of small water conglomerates, which are assumed both to be present in the mesosphere and to have very low ionization thresholds.

Download or read book Aeronomy written by P. M. Banks and published by Elsevier. This book was released on 2013-09-03 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aeronomy, Part B discusses the scientific discipline devoted to the study of the composition, movement, and thermal balance of planetary atmospheres. The book presents the comprehensive exposition of the basic processes involved in the aeronomy of the earth’s upper atmosphere. It demonstrates the chemical, ionic reactions, and the different collisional interactions involving particles and radiation. The text describes the molecular diffusion and its effects in producing the transition from homogeneous molecular gases of lower atmosphere to the heterogeneous atomic and molecular gases of the upper atmosphere. It also discusses the simple models of the ionospheres. Another topic of interest is the calculations of atmospheric photoionization. The section that follows describes the satellite and external hyperbolic particles. The book will provide valuable insights for engineers, scientists, students, and researchers in the field of space science.
