Intercomparison of Polar ionospheric behavior at Arctic and Antarctic region and analysis of polar ionospheric scintillation

In this paper, we investigated the symmetry and asymmetry of Total electron Content (TEC) values at northern and southern hemisphere region ionosphere and their dependence on interplanetary magnetic field (IMF). It also describes the TEC variation co-relation with the amplitude and phase scintillation on polar region. In view of this, the TEC data recorded with the help of Global Ionospheric Scintillation and TEC monitoring (GISTM) system installed at Indian permanent scientific base “Himadri station” [78˚55’N 11˚56’E] and “Maitri station” [70˚46’00”S 11˚43’56”E] has been utilized. The recorded %TEC variation is higher at Antarctic region (-40% to 60%) in comparison to Arctic region (-25% to 25%), it explained the role of sun with the photo ionization process. It is found that TEC variation is a function of magnetosphere–ionosphere coupling and it depends on IMF orientation and magnitude in X, Y, Z plane. It is illustrated that the TEC value at northern region shown an enhancement when Bx<0, By<-6nT or By>6nT and Bz>0 and at southern region when Bx>0,-6nt
