Assessment of Polar Ionospheric Observations by VIPIR/Dynasonde at Jang Bogo Station, Antarctica: Part 1—Ionospheric Densities

Vertical incidence pulsed ionospheric radar (VIPIR) has been operated to observe the polar ionosphere with Dynasonde analysis software at Jang Bogo Station (JBS), Antarctica, since 2017. The JBS-VIPIR-Dynasonde (JVD) provides parameters such as height profile of electron density NmF2 and hmF2, ion drift, tilt in bottomside ionosphere. JBS (74.6°S, 164.2°E) is located cap, cusp, or auroral region depending on geomagnetic activity local time. In present study, an initial assessment JVD densities attempted by comparison GPS TEC measurements which are simultaneously obtained from receiver during solar minimum period 2017 2019. It found that (bTEC) show a generally good correlation for geomagnetically quiet conditions. However, bTEC seems be less correlated slightly larger spreads especially daytime summer, associated characteristics energetic particle precipitations large irregularities. also some limitations handle these needs improved produce more accurate profiles disturbed
