T1 BACKGROUND VARIATIONS IN THE TOTAL ELECTRON CONTENT OF THE IONOSPHERE OVER THE ANTARCTIC PENINSULA JF Radio Physics and Radio Astronomy JO RPRA YR 2012 FD 2012-08-13 VO 3 IS 3 SP 233 OP 240 K1 ionospheric inhomogeneities K1 Total Electron Content K1 GNSS AB Results are presented of investigated variations in the Total Electron Content (TEC) of the ionosphere over the Antarctic Peninsula using data from a local network of permanent GNSS stations for 450 days in 2009 and 2010. Diurnal dependences of the velocities and motion directions of ionospheric inhomogeneities are analyzed for different seasons. In the daytime, the inhomogeneities move predominantly north-eastward at velocities 300 to 500 m/s for all seasons. During the evening hours in autumn and winter the north-western motion direction is prevailing, while in spring and summer the south-western direction dominates. The nighttime ionospheric inhomogeneities are characterized by wider ranges of motion velocities and directions.
