Ground-based Observations of the Polar Region Space Environment
Jang Bogo Station (JBS), the second Korean Antarctic research station, was established in Terra Nova Bay, Antarctica (74.62°S
164.22°E) in February 2014 in order to expand the Korea Polar Research Institute (KOPRI) research capabilities. One of the
main research areas at JBS is space environmental research. The goal of the research is to better understand the general
characteristics of the polar region ionosphere and thermosphere and their responses to solar wind and the magnetosphere.
Ground-based observations at JBS for upper atmospheric wind and temperature measurements using the Fabry-Perot
Interferometer (FPI) began in March 2014. Ionospheric radar (VIPIR) measurements have been collected since 2015 to monitor
the state of the polar ionosphere for electron density height profiles, horizontal density gradients, and ion drifts. To investigate
the magnetosphere and geomagnetic field variations, a search-coil magnetometer and vector magnetometer were installed in
2017 and 2018, respectively. Since JBS is positioned in an ideal location for auroral observations, we installed an auroral all-sky
imager with a color sensor in January 2018 to study substorms as well as auroras. In addition to these observations, we are also
operating a proton auroral imager, airglow imager, global positioning system total electron content (GPS TEC)/scintillation
monitor, and neutron monitor in collaboration with other institutes. In this article, we briefly introduce the observational
activities performed at JBS and the preliminary results of these observations
