The large scale, high latitude ionospheric convection pattern is driven by the interaction of the solar wind and the interplanetary magnetic field with the earths magnetosphere. Ground-based digital ionosondes, with spaced receiving antennas, have been developed and deployed at the high latitude stations of Thule, Greenland and Goose Bay, Labrador. Results from these stations demonstrate that the ionospheric convection can be measured for the bottomside ionosphere. Data from Thule consistently show the predominant antisunward convection. The data from Goose Bay indicate the sunward return flows of the polar plasma convection and the switch over when the station rotates from the dusk into the dawn cell. These data also illustrate the potential for systematic study of the convection patterns that is possible with a network of ground-based digital ionosondes. Author
