Abstract : Our understanding of the solar-terrestrial environment has advanced enormously with the development of satellite technology. Satellites not only provide in-situ measurements of the atmosphere, ionosphere and magnetosphere, they are also able to monitor the incoming radiations and particles, and even provide, at the same time, much broader and denser geographical coverage of parameters that can be measured from the ground. Now that satellites have provided data of various kinds over a complete 22-year solar cycle, the Electromagnetic Wave Propagation Panel deemed it appropriate to hold a symposium on 'The Physical Basis of the Ionosphere in the Solar-Terrestrial System'. The meeting took place in Pozzuoli, Italy, 28-31 October 1980, and was basically dedicated to reviewing our current understanding of the processes that produce and control the distribution of ionization in the ionosphere as a component of the solar-terrestrial system, with some examples of modelling and prediction techniques that can be applied by terrestrial users of the electromagnetic spectrum.
