The occurrence frequency of auroral potential structures and electric fields as a function of altitude using Polar/EFI data [PDF]

open access: yesAnnales Geophysicae, 2004
The aim of the paper is to study how auroral potential structures close at high altitude. We analyse all electric field data collected by Polar on auroral field lines in 1996–2001 by integrating the electric field along the spacecraft orbit to obtain
