Since the operation of the King Sejong Station (KSS) started in Antarctic Peninsula in 1989, there have been continuous efforts to perform the observation for the upper atmosphere. The observations during the initial period of the station include Fabry-Perot Interferometer (FPI) and Michelson Interferometer for the mesosphere and thermosphere, which are no longer in operation. In 2002, in collaboration with York University, Canada, the Spectral Airglow Temperature Imager (SATI) was installed to observe the temperature in the mesosphere and lower thermosphere (MLT) region and it has still been producing the mesopause temperature data until present. The observation was extended by installing the meteor radar in 2007 to observe the neutral winds and temperature in the MLT region during the day and night in collaboration with Chungnam National University. We also installed the all sky camera in 2008 to observe the wave structures in the MLT region. All these observations are utilized to study on the physical characteristics of the MLT region and also on the wave phenomena such as the tide and gravity wave in the upper atmosphere over KSS that is well known for the strong gravity wave activity. In this article, brief introductions for the currently operating instruments at KSS will be presented with their applications for the study of the upper atmosphere.

국내 재배 당근 품종은 대부분 수입에 의존하고 있어 국내 당근산업의 기반을 유지하고 경쟁력 확보를 위하여 우수한 품종을 개발 보급하고자 본 ‘그라운드 킹’을 육성하였다. 근형은 원추형이고, 근피색, 근육색 및 심색은 주황색으로 근피가 매끈하다. 숙기는 중만생종이고, 육질이 연하고 수분이 많다. 병해 저항성은 검은잎마름병 및 흰가루병이 중간 정도로 대비품종인 ‘양면’과 비슷하고, 추대에 다소 약하므로 조기 파종 할 때 추대 위험이 있다. 수량은 3,228 kg/10a이고, 근장은 16.3 cm, 근중은 171.0 g으로 대비품종 ‘양면’ 166.5 g과 비슷하다. 추대율은 3.9%로 양면 5촌의 2.4%보다 다소 높아 조기 파종시 추대의 위험이 있으므로 적기에 파종하여야 한다.
