Foreword

For me as an early participant in space research it was mandatory to study the ionosphere, since it was in this environment that our experiments with plasma clouds were performed. The textbooks available at that time emphasized production and loss of ions and electrons by photoionization and particle collisions, i.e. local processes. Rocket experiments with neutral gas releases and plasma cloud injections showed, however, that coupling between regions was essential for understanding our results. The same applied to the rising research with incoherent scatter radar. On the one hand, there was besides particle precipitation the downflow of momentum and electromagnetic energy and the closure of electric currents from the magnetosphere. On the other hand, a feedback from the ionosphere was recognized as controlling magnetospheric dynamics and structuring. While ionospheric physics was greatly enriched
