Global modeling of thermospheric airglow in the far ultraviolet

It can be run using inputs from empirical models of the neutral atmosphere and ionosphere or from numerical general circulation models of the coupled ionosphere-thermosphere system.

It uses a solar flux module, photoelectron generation routine, and the Nagy-Banks two-stream electron transport algorithmto simultaneously handle energetic electron distributions from photon and auroral electron sources. It contains an ion-neutral chemistry module that calculates excited and ionized species densities and the resulting airglow volume emission rates. This paper describes the inputs, algorithms, and code structure of the model and demonstrates example outputs for daytime and auroral cases.
