Title: Ionospheric Modelling during the Past Decades
Authors: Rawer, K
Issue Date: Oct-1986
Publisher: NISCAIR-CSIR, India
Abstract: Starting with oversimplified models (e.g. reflecting mirror) geometrical optics in a parabolic layer achieved a satisfactory explanation of the most important phenomena in ionospheric hf-propagation. Later, more detailed descriptions of the electron-density profile were developed, e.g. the International Reference Ionosphere. These are based on ground and space observations. The C.C.I.R. 'numerical maps' describing the world-wide behaviour of the peak data are rediscussed now. Sophisticated theoretical models based on aeronomic theory have been developed during the last 15 years. These need an enormous computing effort.
