Project: Phenomena coupling the neutral and ionized atmosphere

An investigation of coupling between the neutral and ionized atmosphere with focus on ionospheric variability is proposed. Processes that influence the ionosphere from below and above will be studied. Main topics of the proposed research will be: A) Propagation of atmospheric waves in the low-latitude and mid-latitude ionosphere. B) Impact of convective systems and other extreme weather and seismic events on the ionosphere. C) Ionospheric irregularities like spread F and plasma bubbles, their occurrence and propagation. D) The influence of solar activity on the long-term and short-term variability of the ionosphere and related modeling. E) Comparison of experimental data from various ground based measurements (Continuous Doppler sounding, ionosonde, GPS network, optical observations,…), satellite observations (COSMIC, SWARM, C/NOFS) and outputs from atmospheric and ionospheric models. The project covers mostly basic geophysical research, the obtained results might however contribute to more sophisticated ionospheric corrections in GPS navigation systems.
