Ionospheric Radiowave Absorption Processes in the Dayside Polar Cap Boundary Regions

  • Chapter
Polar Cap Boundary Phenomena

Part of the book series: NATO ASI Series ((ASIC,volume 509))

Abstract

Radio wave absorption processes in the upper, partly ionized atmosphere, the ionosphere, hold a unique source of information on the physics of these regions. The detection of absorption processes has been greatly augmented by the advance of the imaging riometer technique and the deployment of a number of imaging riometer installations in the polar regions. The present report discusses the theoretical foundation for the use of absorption observations for the diagnostics of the ionospheric plasma conditions and for the examination of the precipitation of high-energy charged particles into the upper atmosphere. A survey of absorption event types of relevance for the polar cap boundary regions is given. Example cases of some of these absorption event types are presented to illustrate the physics involved in such events and to describe the observing systems, the data handling techniques, and the analysis and display tools available.
