JAIC: the Jupiter auroral ionosphere code

JAIC is an open-source code for modelling electron precipitation and related ionospheric / auroral processes in Jupiter’s upper atmosphere. The hybrid model follows the primary electron population using a Monte Carlo code that runs on an NVIDIA GPU, and computes the contribution of the secondaries using a two-stream approximation.  The model includes modules that compute high resolution far-ultraviolet H₂ spectra, the H₃⁺ density using simple ion chemistry, and the resulting Pedersen conductivity and H₃⁺ radiance.  This version uses a grid spaced logarithmically in pressure.
