Description:
The paper reviews the current state of GNSS-based detection, monitoring and forecasting of ionospheric perturbations in Europe in relation to the COST action ES0803 ‘‘Developing Space Weather Products and Services in Europe’’. Space weather research and related ionospheric studies require broad international collaboration in sharing databases, developing analysis software and models and providing services. Reviewed is the European GNSS data basis including ionospheric services providing derived data products such as the Total Electron Content (TEC) and radio scintillation indices. Fundamental ionospheric perturbation phenomena covering quite different scales in time and space are discussed in the light of recent achievements in GNSS-based ionospheric monitoring.
Thus, large-scale perturbation processes characterized by moving ionization fronts, wave-like travelling ionospheric
disturbances and finally small-scale irregularities causing radio scintillations are considered. Whereas ground and space-based GNSS monitoring techniques are well developed, forecasting of ionospheric perturbations needs much more work to become
attractive for users who might be interested in condensed information on the perturbation degree of the ionosphere by robust indices.
Finally, we have briefly presented a few samples illustrating the space weather impact on GNSS applications thus encouraging
the scientific community to enhance space weather research in upcoming years.
