Abstract:

Work on aurora models by NRLs Plasma Dynamics Branch is reported. Correlations between auroral phenomena and high altitude nuclear explosion effects are discussed. An improved proton deposition code is described which includes cross sections for O2, O and N2 interactions with protons. The accuracy of the NRL electron deposition code for large angle scattering has been confirmed by a study of electron backscatter. An analysis of NO densities observed in auroral arcs is also presented. The report concludes with a presentation of recent improvements in the NRL auroral electrodynamic models.
