Initial Study of Inversion Method for Estimating Energy Spectra of Auroral Precipitating Particles from Ground‐Based is Radar Observations
Abstract The principles and methods to estimate auroral precipitating particles' energy flux spectra from electron density from ground‐based incoherent scatter (IS) radar have been investigated in this paper. Fieldaligned measurements from EISCAT radar at Tromsø are used to estimate related res...
