Electron density distribution over the magnetic equator
Abstract
Study of the electron density distributions over Thumba for two solar epoch years - 1965, a year of low solar activity, and 1967, a year of high solar activity. Standard profiles were obtained for quiet days, and the effect of magnetic disturbance is studied by comparing various ionospheric parameters for quiet and disturbed days. Data suggest that ionization which is normally transported away around midday from the equator to the crest regions on quiet days remains at the equator itself on disturbed days. It is suggested that this may be due to the equatorial electric fields weakening during disturbed conditions, resulting in a reduction of the vertical E x B uplift of equatorial ionization.
