GOSAT과 안면도 지상 관측소에서 측정된 이산화탄소의 상관성 분석

다국어 초록 (Multilingual Abstract)

GOSAT satellite CO₂ signal in years (June, 2009 December 2012) were compared with ground-based measurement at Anmyeon-do Korea Global Atmosphere Watch Center (KGAWC), located on the west coast of the Korean Peninsula. The result reveals that GOSAT signature is closely associated with ground-based measurement(R² = 0.49). Strong correlation occurred between summer and fall (R² = 0.62) while weak relationship between satellite and ground-based measurement were identified in winter and spring (R² = 0.37). Average CO₂ concentration of GOSAT were 6.31 ppm lower than the corresponding values obtained from ground-based measurements on the same date. It is anticipated that this research output could be used as a valuable reference in introducing GOSAT to confirm data quality assurance for area-wide carbon monitoring process in relation to Anmyeon-do KGAWC CO₂ Concentration data.
