초록

한국우주과학회 태양우주환경분과에서는 국내 우주환경 관측 자료 활용도를 높이고, 분야 간 융합 연구 기회를 모색하기 위해 국내 연구소와 대학에서 활용 중인 태양, 자기권, 전리권/고층대기 자료 현황을 조사하였다. 자료는 관측 방식에 따라 지상과 위성 자료로 분류하였고, 개발 또는 활용 중인 모델 정보도 포함한다. 이 논문에서는 조사 결과를 바탕으로 극지연구소와 한국천문연구원에서 운영하는 전리권/고층대기관측기 현황과 자료 설명 및 활용 방법 등을 소개한다. 극지연구소에서는 남극 장보고과학기지와 세종과학기지, 그리고 북극 다산과학기지에 전천 카메라, 페브리-페로 간섭계, 이오노존데 등을 설치해 운영 중이다. 한국천문연구원은 보현산천문대 전천카메라와 충남 계룡대 VHF(Very High Frequency)/유성 레이더를 운영하고 있으며, 국내 40여 개 GNSS(Global Navigation Satellite System) 관측소에서 수집한 자료를 사용해 전리권 전자밀도 정보(total electron content)를 산출하고 있다. 또한 보현산천문대와 탐라 KVN천문대에 GNSS 신틸레이션 수신기를 설치해 전리권 교란을 관측하고 있다. 현재 관측 자료들은 웹 페이지나 FTP, 또는 요청을 통해 이용할 수 있다. 이 밖에 논문에 담지 않은 기타 전리권/고층대기 분야 자료 현황은 한국우주과학회 홈페이지에서 다운로드할 수 있다(http://ksss.or.kr/). 이 논문을 통해 우주과학 연구자들이 우주과학 자료에 대한 장기적이고 연속적인 관리의 중요성을 인식하고, 국내에서 생산 중인 자료의 활용도와 신뢰도를 높이는 데 이바지할 수 있길 기대한다. 더불어 국내 관측 자료의 활용을 극대화하기 위한 새로운 데이터 공유 체계에 관한 논의를 시작하는 계기가 되길 바란다.

In 2020, the solar and space environment division at the Korea Space Science Society surveyed the status of data archives in solar physics, magnetosphere, and ionosphere/upper atmosphere in Korea to promote broader utilization of the data and research collaboration. The survey includes ground- and satellite-based instruments and developing models by research institutes and universities in Korea. Based on the survey results, this study reports the status of the ground-based instruments, data products in the ionosphere and upper atmosphere, and documentation of them. The ground-based instruments operated by the Korea Polar Research Institute and Korea Astronomy and Space Science Institute include ionosonde, Fabry-Perot interferometer in Arctic Dasan stations, Antarctic King Sejong/Jang Bogo stations, and an all-sky camera, VHF radar in Korea. We also provide information on total electron content and scintillation observations derived from the Global Navigation Satellite System (GNSS) station networks in Korea. All data are available via the webpage, FTP, or by request. Information on ionospheric data and models is available at http://ksss.or.kr. We hope that this report will increase data accessibility and encourage the research community to engage in the establishment of a new Space Science Data Ecosystem, which supports archiving, searching, analyzing, and sharing the data with diverse communities, including educators, industries, and the public as wells as the research scientist.
