Case Studies of Ionospheric Plasma Irregularities Over Queen Maud Land, Antarctica
We use the first data set from the ground-based TEC and scintillation receiver located at the Norwegian Research Station Troll in Queen Maud Land, Antarctica to analyze in detail the ionospheric response during geomagnetic disturbances on February 26-27 and March 18-19, 2018. By combining the Troll...
