A number of problems have been addressed in this work. They have been accompanied by extensive code development which has led to new capabilities such as the modeling of O diffusion and to some significant reductions in code running times and disk allocation requirements. The given problems, either directly or indirectly, have dealt with the issue of using satellite optical systems to monitor ionospheric conditions. The central question of interest is How accurately can the E and F region electron density profiles ne be determined from satellite optical data on a global scale. We have addressed this question as it pertains to the auroral E region and low to mid-latitude daytime E and F regions. Most of the reported work is on the first of these regions. The approach has been from first principles in which we start with either an incident auroral electron spectrum or a solar EUVX-ray spectrum and proceed to determine the associated electron distribution function followed by its associated excitation and ionization rates, optical intensities, and electron and ion densities.
