Book Description
An electron density model, which permits a three-dimensional specification of the ionospheric structure, has been developed. The model generates realistic electron density profiles in the altitude range from 100 to 800 km by making use of selected ionospheric parameters that are routinely observed. The model also allows for the calculation of the electron distribution over the entire path of propagation of a radio signal by employing a synoptic mapping technique. The mapping technique enagles ionospheric parameters observed at specific locations to be extended and extrapolated to regions where data are not normally accessible. The electron densities that are computed are done in a manner that is totally consistent with the observed parameters needed to generate the profiles. (Author).

Book Description
An automated objective analysis procedure was developed to represent the global distribution of selected ionospheric parameters on a daily basis. The analysis scheme enables the incorporation of observations or predictions of ionospheric parameters from random locations on the globle into a synoptic mapping technique that yields updated values of the parameters at specific grid points. In this report, the steps taken in the development of the analysis procedure and the accuracy of the results of global mapping of the F2 region critical frequency are described. (Author).

Book Description
Using the method of Rush and Gibbs (1973), weighted means of observed values have been used to update the global prediction of f(o)F2, which are based on monthly median values derived from the Institute of Telecommunications Sciences model (1969). This procedure improved the predictions for magnetically quiet periods, for times near minimum of the solar cycle phase, and for the equinoctial months. Furthermore, a closer grid of ionosonde stations resulted in reducing the error in the f(o)F2 prediction. For the method of Rush and Gibbs (1973) to be operationally successful in global predictions of f(o)F2 however, a closer grid of ionosondes than is presently available is needed. (Author).

Book Description
Authored by leading international researchers, this monograph introduces and reviews developed tomograhic methods for discovering 2D and 3D structures of the ionosphere, and discusses the experimental implementation of these methods. The detailed derivations and explanations make this book an excellent starting point for non-specialists.

Book Description
An instrument to remotely determine neutral density profiles in the lower thermosphere has been developed. The instrument observes ultraviolet airglow profiles in two bands: the 3371 A band for nitrogen and the 1356 A band for atomic oxygen to infer atmospheric density. Calculations of the intensities of these emissions have been made using the recent computations of energy dependent photoelectron fluxes and experimental determinations of the excitation cross section.
