Author Description

This volume contains thirty-three papers selected from the COSPAR Colloquium on Low-Latitude Ionospheric Physics in which many new results of ground based observations, satellite observations and numerical simulations were presented. The equatorial ionosphere is especially interesting as there, the Earth's magnetic field is horizontal and the Coriolis force vanishes at the geographic equator, resulting in the occurrence of many fascinating phenomena. A considerable proportion of the papers discuss either large scale or small scale irregularities of the equatorial ionosphere. Details are also included on the new technique of ionospheric tomography, which will have applications extendable beyond the ionosphere in the future.
