Recent aspects of ionospheric scintillation observations
Abstract
Scintillation occurrence and scintillation intensity depend upon frequency, location, propagation path geometry, geophysical conditions, receiving equipment characteristics, - such like the receiving antenna beamwidth, the receiver resolution and stability, and the data acquisition facilities - and the measure used to describe scintillation. This causes many problems by comparing data from different sources. After fifty years of ionosphere research and more than twenty years of intensive scintillation measurements future experimental trends might be as much determined by some already visible limitations as by the application of the very recent advanced technologies. Both aspects are mentioned here. There are two principally different methods to investigate the scintillation producing irregularities in the ionosphere: 1. In situ measurements, 2. Remote sensing methods. It is shown that three different experimental possibilities to improve our knowledge about the scintillation producing irregularities in the ionosphere. The first one, possibly the most important at present is based upon a new experimental technique (VIGODOS) which possibly will allow a better, faster and easier understandable and more efficient combination of preedited data that stem from radar experiments, satellite radio beacon experiments, aurora and airglow measurements, as well as from in situ experiments.
