Available in PDF, EPUB and Kindle. Book excerpt: An aeronomic analysis is made of effective bremsstrahlung effects which are due to electrons penetrating into the upper atmosphere in the auroral zone. The electron attenuation in the atmosphere is determined from a Monte Carlo model which includes electron energy loss and scattering processes. A comparison is made between experimental results and the calculated energy deposition rates. Typical electron energy and angular distributions as a function of depth of penetration are given. Bremsstrahlung production rate profiles are obtained using the Bethe-Heitler cross sections which include the angular as well as the energy dependence. Numerical calculations are made of the ion production rates for a number of electron precipitation events which were observed. Electron energy distributions are obtained by suitably weighting basic calculations for 5, 10, 15, 25, 35, 50, 70, 100, 150, and 500 kev mono-energetic electrons. The bremsstrahlung ion production rates in the D region are found to be significant primarily for intense fluxes of 1 - 20 kev electrons usually associated with visible auorora. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Existing formulae for bremsstrahlung cross-sections for charged particles precipitating into the lower ionosphere at high latitudes have been corrected to include the dependence on angle in the photo-ionization by bremsstrahlung photons. The study of polarization of bremsstrahlung X-rays in the lower ionosphere disclosed that the polarization parameters vary with height and are energy dependent so that precision measurement of X-ray polarization could be used for diagnostic purposes. It was found that the effect of an electric field along field lines on whistler-mode waves results in unducting of the wave. For processes in the equatorial electrojet it was concluded that the two-stream instability criteria is not satisfied during the westward current flow and magnetic-field depressions are correlated with the disappearance of equatorial sporadic-E traces on ionograms. A secondary peak in intensity distribution of synchrotron radiation from a weakly-relativistic electron plasma is interpreted as being due to scattering of radiation by plasma inhomogeneities.

This book was released on 2012-12-06 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: These proceedings are based upon the review lectures, the re search talks and the accompanying discussion from the NATO Advanced Study Institute on "The Dynamical and Chemical Coupling of the Neutral and Ionized Atmosphere" held at Spatind, Norway April 12-22, 1977. In recent years, in spite of the many subdivisions of atmospher ic physics it has become clear that a complete understanding of the subject matter requires an interdisciplinary effort of the scien tists working on a variety of atmospheric phenomena. This Advanced Study Institute was organized in order to meet this demand. A number of eminent scientists were invited to review the major subfields in atmospheric physics and expose the areas where the coupling between the neutral and ionized atmosphere is evident. These review papers were supported by current research results. However, the material covered here is by no means complete con sidering the range of subject matter covered by the title. The re sponsibility for this inadequacy lies with the editors and the pro gram committee, rather than with the individual contributors. Oslo, June 1977. B. Grandal J.A. Holtet.
