    Description
    In March 2008, discrete stable auroral arcs were investigated during a coordinated observational campaign between the European Incoherent Scatter Radar (EISCAT) and the Auroral Large Imaging System (ALIS). The two sets of data are inverted to retrieve fluxes of precipitating electrons. Both results are matching in energy and shape with a typical average precipitation energy of a few keV. Finally, by using the average energy spectrum of electrons deduced from ALIS data as input for the TRANS4 kinetic/fluid electron transport 1D model, computed auroral emissions are compared to ALIS observations and electron density profiles are compared to EISCAT profiles. .
