Description:
The auroral oval is the region receiving most magnetospheric particle precipitations and its boundaries can be highly dynamic and influenced by the solar wind and geomagnetic conditions. Polar orbiting Low Earth Orbit (LEO) satellites carrying high-precision magnetometers are suitable to derive Field-Aligned Currents (FACs) with tens of km-scale lengths flowing between the magnetosphere and ionosphere. Our previous work has used nearly 10 years FAC data from the CHAMP mission to construct an empirical model (called CH-Aurora-204) for estimating the location of the auroral oval boundaries. The model has been recently updated by taking nearly 5 years FAC data from the three Swarm satellites. Furthermore, magnetic data from other non-dedicated magnetic LEO missions, like Cryosat or e-PoP, are also used for improving the model predicts of the auroral oval boundaries.
