Description of the main research interests and activities of the team/lab:

The research activity of the group lies in the context of the study and mitigation of ionospheric effects on radio systems. It is in the position to pursue this aim by means of its infrastructure that facilitates continuous remote sensing of the state of the ionosphere, within various parts of the electromagnetic spectrum (VLF, HF, UHF). Detrimental ionospheric effects on radio systems usually have their origin on the disturbed state or natural variability of the Sun and therefore the group has a genuine research interest on Space Weather and its subsequent impact on the Upper Atmosphere. The ultimate goal of the group is to conduct studies on ionospheric variability and explore various techniques on monitoring and modeling of ionospheric characteristics in support of systems such as HF communication networks and GNSS.

Description of the main equipment/facilities available:
The ionospheric group has top-edge equipment for systematic near-real time high resolution ionospheric measurements primarily based on a modern digital ionosonde radar (DPS-4D). This is complemented by a HF spectral occupancy monitoring which provides information on HF spectral characteristics. Ionospheric related infrastructure is also extended by monitoring systems in the UHF and VLF bands. A scintillation monitor for monitoring scintillation parameters and Total Electron Content (TEC) in collaboration with Nottingham University, UK and an AWESOME (Atmospheric Weather Electromagnetic System of Observation, Modeling, and Education) VLF instrument in collaboration with Stanford, USA.

Research Projects Experience:
Over the last 7 years, the team has completed 4 projects and is currently implementing 2 projects as a coordinator that obtained funding from competitive calls of RPF. The team has participated in European research consortia for securing funding in the area of Ionospheric monitoring and modeling project proposals. Moreover, the team has participated in COST actions COST296 “Mitigation of Ionospheric Effects on Radio Systems” and ES0803 “Developing space weather services and products in Europe”.

Presently, the team is collaborating with several institutions, such as Stanford University (USA), Nottingham University (UK), Istituto Nazionale di Geofisica e Vulcanologia (ITALY) and the Center for Atmospheric Research of the University of Massachusetts – Lowell (USA).
