AB: Height profiles of the electron density in the E-layer and upper D-region can be derived on a global scale using remote sensing of UV- and X-ray emissions by the UVI and PIXIE cameras onboard the Polar-satellite. The first step in the procedure is to use the UVI and PIXIE measurements to estimate the precipitating electron energy spectra from less than 1 keV to 100 keV. From the electron spectra, we then infer the height profiles of the electron density. In this study, we investigate the reliability of the derived electron density values by comparing with simultaneously measured height profiles of the electron density by the EISCAT radar located at Tromso, Norway.
