|Multi-Scale Variations in Auroral Electron Precipitation|
AbstractThe goal of this project is to study auroral precipitation using a unique setup of satellite-based in-situ measurements and ground-based observations, with the application of state-of-the-art generalised tomography-like methods. We aim to build a full three-dimensional picture of the energy spectra of precipitating particles. The particle energy distribution and its variations control the auroral excitations, and have an important impact on various ionospheric processes as well as affecting the composition and chemistry of the high latitude upper-atmosphere. Variations in the electron precipitation energies are ultimately driven by solar wind and magnetospheric activity and therefore are a convenient way to gain new information on several processes taking place in the near-Earth plasma environment.
The project will include two meetings of all team members at ISSI, with an expected outcome of one concluding paper and additional scientific and technical publications. The new analysis tools resulting from the proposed project will improve the capability of ground-based support for current and future spacecraft missions and complement the upcoming next generation European incoherent scatter radar system (EISCAT_3D). The project will also deliver recommendations for the deployment of supporting instrumentation for EISCAT_3D and future spacecraft missions.
Team meetingsThe first meeting took place at ISSI in Bern, 4-8 Jan 2016.
