dc.description.abstract | Accurate models of trans-ionospheric propagation are needed to assess the role of Earth-originating very low frequency (VLF) electromagnetic waves in radiation belt dynamics. Recent studies have called the relatively crude early trans-ionospheric models into question, finding that they underestimate the attenuation by 20–100 dB. A full wave model that includes all of the relevant physics has recently become available and experimentally verifed to within a few decibels via comparison to more extensive satellite data. Using this model, we discuss the importance of wave polarization, incidence angle, bearing, ground conductivity, horizontal distance from the source, and the ionospheric pro?le, all of which are demonstrated to play a signifcant role in the trans-ionospheric propagation. Trans-ionospheric attenuation estimates are provided both for the case of vertical incidence of a whistler-mode wave and for the case of magnetospheric injection from a dipolar terrestrial VLF source.
