| Abstract: | Some preliminary hourly values of total ionic velocity in the upper E-region (122–144 km) are presented and the magnetic meridian component of horizontal neutral wind, averaged from observations on 14 days spread over about two years, is studied. The semi-diurnal variation is found to be predominant at 122 km, almost exactly in phase with the same component at St. Santin (France). Knowledge of the complete ionic velocity allows the rigorous calculation of the meridian perpendicular component of the electric field, some preliminary values of which are presented. |
