AURIC airglow modules: phase 1 development and application

R. Link, D. J. Strickland, and R. E. Daniell, Jr.

Computational Physics Inc. is developing numerical codes for the Atmospheric Ultraviolet Radiance Integrated Code (AURIC) development effort of the Phillips Laboratory Geophysics Directorate in the area of Ionospheric Impact on Air Force Systems - Ultraviolet Remote Sensing. The modules will calculate thermospheric emission spectra and radiances in the 1000 - 6500 Å wavelength region for dayglow, nightglow, twilight, and electron aurora, and will account for solar, photoelectron, auroral electron, and chemical excitation processes, pure and self absorption, and multiple scattering effects. The modules will provide the capability to calculate emission spectra as a function of wavelength and look angle, or provide radiances integrated over specified wavelength intervals for user-selected viewing geometries. The integrated codes will provide a powerful tool for computing UV optical backgrounds, analyzing optical data, and designing sensors. This paper presents the overall architecture of the codes. The design and implementation of the photoionization and electron flux modules is discussed, and examples of the input data and generated output is shown.
