ABSTRACT:

The ionospheric F-iayer at sunrise is investigated by applying data obtained at Ibadan (Magnetic latitude 3°5) to the electron densi.ty continuity equation. Results obtained indicate that the rate of change of electron density increases with· time IA the neighbourhpod of ground sunrise. The movement term in the continuity equation is established as the major factor governing ionization density changes at sunrise.· The results are also comparable with earl.er works at the same station using horizontal drift measurements, for equinoctial and solsticial conditions
