|Abstract:||Electron drifts distributions obtained from ionosonde measurements at Ibadan (lat. 7.4oN, long. 3.9oE; magn lat. 3.0°S), Nigeria, have been used to estimate daytime F-region vertical drift velocities during periods of low and high solar activity. Values of the drift velocity near 300 km altitude at Ibadan are shown to be in good agreement with the results of experiments carried out at other equatorial stations. The proposed method may be relevant to the bottomside ionosphere for estimating vertical drift velocities, especially, at locations close to the magnetic equator where measurements are not carried out on a continuous basis. |
