Abstract

The radiation observation data will be used importantly in research field such as climatology, weather, architecture, agro-livestock and marine science. The Ieodo Ocean Research Station (IORS) is regarded as an ideal observatory because its location can minimize the solar radiation reflection from the surrounding background and also the data produced here can serve as a reference data for radiation observation. This station has the potential to emerge as a significant observatory and join a global radiation observation group such as the Baseline Surface Radiation Network (BSRN), if the surrounding of observatory is improved and be equipped with the essential radiation measuring instruments (pyaranometer and pyrheliometer). IORS has observed the solar radiation using a pyranometer since November 2004 and the data from January 1, 2005 to December 31, 2015 were analyzed in this study. During the period of this study, the daily mean solar radiation observed from IORS decreased to $-3.80W/m^2/year$ due to the variation of the sensor response in addition to the natural environment. Since the yellow sand and fine dust from China are of great interest to scientists around the world, it is necessary to establish a basis of global joint response through the radiation data obtained at the Ieodo as well as at Sinan Gageocho and Ongjin Socheongcho Ocean Research Station. So it is an urgent need to improve the observatory surrounding and the accuracy of the observed data.

정확한 복사 관측자료는 기후 및 날씨뿐만 아니라 해양과 건축 및 농 축산 분야 등 중요하게 활용된다. 특히 이어도와 같은 종합 해양과학기지는 주변 환경에 의한 복사 반사 효과를 최소화할 수 있기 때문에 이상적인 관측소로 평가되며 여기서 생산되는 자료는 복사관측의 기준 자료가 될 수 있다. 또한 BSRN (Baseline Surface Radiation Network) 등 세계복사관측그룹 가입을 위한 필수 장비들(전천과 직달 및 산란 일사계 등)을 갖추고 관측소 환경을 개선할 경우 전 세계적인 중요 관측소로 부각될 수 있는 여건을 갖추고 있다. 이어도 종합해양과학기지는 2004년 11월부터 일사계 관측을 수행해 왔고 이 연구에서는 2005년 1월 1일부터 2015년 12월 31일까지의 자료를 분석하였다. 이 연구 기간에 이어도의 일평균 일사량은 $-3.80W/m^2/year$로 감소하였고 그 이유는 자연적 원인 이외에 관측장비의 센서 반응도 감소 효과가 포함되어 있기 때문이다. 즉 이어도 종합해양과학기지의 경우 정밀한 복사 관측 자료를 생산하기 위해서는 관측소 환경 개선뿐만 아니라 관측장비 및 자료 보정이 요구된다. 그리고 한반도의 대기 청정도와 국민 건강을 크게 위협하고 있는 중국발 황사와 미세 먼지는 전 세계 과학자들의 중요 관심 대상이기 때문에 이어도뿐만 아니라 신안 가거초 및 옹진 소청초 종합해양과학기지 복사 관측자료를 통한 공동 대응 근거 마련이 필요하며 그에 따라 이들 복사관측소 환경 및 장비 개선 그리고 관측자료 정확성 향상 계획 수립이 시급하다.
