AURORA is a time-dependent multi-stream electron transport code, suitable for modeling ionospheric electron-fluxes during periods of rapidly varying electron-precipitation (sub-second).
This is a Julia implementation of the original AURORA code written in MATLAB and available at https://github.com/egavazzi/AURORA. This version is the one we recommend to use. It is in active development, is much faster (~ 1000x), and produces more accurate results (i.e. bugs have been fixed).
Below is an example of electron flux in the ionosphere produced by AURORA in response to Alfvénic precipitation.

Instructions are available in the documentation.
Descriptions of how the code works are available in Gustavsson (2022), in section 3 of Gavazzi (2022), and in this document.
