Download or read book On Water Cluster Ions in the Ionospheric D Region written by R. S. Narcisi and published by . This book was released on 1970 with total page 24 pages. 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 Positive Ion Composition Measurements in the Lower Ionosphere During the 12 November 1966 Solar Eclipse written by Rocco S. Narcisi and published by . 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 Model Studies of the Lower Ionosphere written by John N. Rowe and published by . This book was released on 1972 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: A summary of quiet D-region electron density measurements made by the wave interaction technique at The Pennsylvania State University for the period October 1969 - January 1971 is presented. Some estimate of the uncertainty in these measurements is given also. The mean electron density profile for July 1970 noon and the measured relative positive ion composition are used as constraints to develop a model of D-region ion chemistry between 60 and 80 kilometers. The neutral densities were taken from previous experimental and theoretical studies. Electron production rates due to Lyman-alpha, ultraviolet, x-rays, and galactic cosmic rays were considered. Some estimates are reported of the rate of conversion of NO+ ions into water cluster ions, the NO density and the detachment rate. It is concluded that the model developed for summer noon conditions will predict reasonably well the average seasonal and diurnal behavior of the D-region electron density, in spite of uncertainties in the neutral chemistry.

Book excerpt: This report presents an objective discussion of the importance of the atmospheric/solar-terrestrial system to national energy programs. A brief sketch is given of the solar-terrestrial environment, extending from the earth's surface to the sun. Processes in this natural system influence several energy activities directly or indirectly, and some present and potential energy activities can influence the natural system. It is not yet possible to assess the two-way interactions quantitatively or to evaluate the economic impact. An investment by the Department of Energy (DOE) in a long-range basic research program would be an important part of the department's mission. Existing programs by other agencies in this area of research are reviewed, and a compatible DOE program is outlined.
Download or read book Proceedings of COSPAR Symposium on Solar Particle Event of November 1969 written by James C. Ulwick and published by . This book was released on 1972 with total page 722 pages. Available in PDF, EPUB and Kindle. Book excerpt: A COSPAR-sponsored Symposium on Solar Particle Events was held at Boston College at Chestnut Hill, Massachusetts on 16, 17, and 18 June 1971. The purpose of the symposium was to present measurements and observations made during the November 1969 Solar Proton Event. This particular event was unique in that extensive solar, magnetospheric and aeronomic measurements by rocket, satellite and ground based techniques were made to provide a comprehensive picture of the phenomenology and morphology of this event. In addition, present knowledge of solar proton events and their effects on the polar ionosphere was reviewed and discussed. This included theoretical studies as well as results from investigations of other solar proton events. The symposium comprised invited as well as contributed papers. A total of 49 papers presented at the symposium are included in these proceedings.
Download or read book Physics and Chemistry of Upper Atmosphere written by Billy McCormac and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the lecmres presented at the Summer Advanced Study Institute, 'Physics and Chemistry of Upper Atmospheres' which was held at the University of Orleans, Orleans, France, during the period July 31 through August 11,1972. One hundred thirty nine persons from 14 different countries attended the Institute. The authors and the publisher have made a special effort for rapid publication of an up-to-date status of the particles, fields, and processes in the earth's magnetosphere, which is an ever changing area. Special thanks are due to the lecturers for their diligent preparation and excellent presentations. The individual lectures and the published papers were deliberately limited; the authors' cooperation in conforming to these specifications is greatly appreciated. The contents of the book are organized by sub ject area rather than in the order in which papers were presented during the Institute. Many thanks are due to Warren Berning, Donald M. Hunten, Edward Llewellyn, J. Ortner, Henry Rishbeth, Harold I Schiff, Lance Thomas, Alister Vallance Jones, and Gilbert Weill, who served as session chairmen during the Institute and contributed greatly to its success by skillfully directing the discussion period in a stimulating manner after each lecture.

Download or read book Literature 1977 Part 2 written by Siegfried Böhme and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 796 pages. Available in PDF, EPUB and Kindle. Book excerpt: Astronomy and Astrophysics Abstracts, which has appeared in semi-annual volumes since 1969, is de voted to the recording, summarizing and indexing of astronomical publications throughout the world. It is prepared under the auspices of the International Astronomical Union (according to a resolution adopted at the 14th General Assembly in 1970). Astronomy and Astrophysics Abstracts aims to present a comprehensive documentation of literature in all fields of astronomy and astrophysics. Every effort will be made to ensure that the average time interval between the date of receipt of the original literature and publication of the abstracts will not exceed eight months. This time interval is near to that achieved by monthly abstracting journals, com pared to which our system of accumulating abstracts for about six months offers the advantage of greater convenience for the user. Volume 20 contains literature published in 1977 and received before February 20, 1978; some older literature which was received late and which is not recorded in earlier volumes is also included. We acknowledge with thanks contributions to this volume by Dr. J. BouSka, Prague, who surveyed journals and publications in Czech and supplied us with abstracts in English, and by Prof. P. Brosche, Bonn, who supplied us with literature concerning some border fields of astronomy.
