Electron density and temperature profiles in the mid latitude ionosphere are derived from the ''resonance cone'' in the radiation pattern of high-frequency point antennas aboard a sounding rocket. By comparing the shapes for reversed wave propagation direction it is possible to study electron drift motion and field-aligned beams. The data from the COREX-I (Cooperative Resonance Cone Experiment) experimeint show close agreement of electron density and temperature profiles from resonance cones with results from independent instruments. There was no indication of a substantial temperature anomaly at E region altitude during this flight. An unexpected electron drift can be interpreted as electron Hall current in the presheath of the negatively charged payload. Field-aligned beams, which have been suggested in connection with the temperature anomaly, were not detected. ¿ American Geophysical Union 1993
