본 연구는 정지궤도 해색 위성 천리안-2B의 해색 센서 GOCI-II 분광지수와 기상 요인 간의 정량적 연계성을 내륙 수체인 안동호 사례를 통해 분석한다. L2 AC(Atmospheric Correction) 산출물 중 Rayleigh 보정 반사도(Rho_C)를 기반으로 FLH(Fluorescence Line Height), NDVI(Normalized Difference Vegetation Index), NDCI(Normalized Difference Chlorophyll Index), NDTI(Normalized Difference Turbidity Index), MCI(Maximum Chlorophyll Index)를 산출하고, 시간 단위 기상자료(강수량, 기온, 풍향, 풍속) 시계열 데이터와 결합하여 분석한다. 피어슨 상관계수(r)와 p-value를 이용해 통계적 유의성을 평가한 결과, 대부분의 조합에서 p < 0.05의 통계적 유의성이 나타났으나, 상관계수는 대체로 |r| < 0.3 범위에 분포하였다. 통계적 유의성만으로 기상 요인과 분광지수 간의 직접적 관련성을 판단하기 어려우며, 내륙 수체에서는 보다 정교한 분석 접근이 요구된다.
