Republic) “Magnetosphere - ionosphere-troposphere coupling and its impact on ionospheric variability” Czech Director: Dra. Dalia Buresova Arg. Director: Prof. Marta Mosert The main aim of this project is to examine the contribution of AGWs excited by meteorological processes to ionospheric variability and energy balance of the ionosphere. The experimental part of the project consists predominantly in collecting, manual checking and analysis of data obtained from ionosonde and Doppler network, microbarographs and GPS.
