본 연구에서는 COMS (Communication, Oceanography and Meteorology Satellite) 위성의GOCI (Geostationary Ocean Color Imager) 센서와 Himawari-8 위성의 AHI (Advanced Himawari Imager) 센서에서 산출되는 에어로졸 광학두께 (Aerosol Optical Depth; AOD)를 활용하여 단일화된 AOD 합성장을 생산하였다. 위성 간의 공간해상도와 위치좌표계가 다르기 때문에 이를 맞춰주는 전처리 작업을 선행하였다. 이후 지상관측 기반인 AERONET (AErosol RObotic NETwork)의 레벨 1.5 AOD 자료를 사용하여 각 위성과 AERONET과의 상관관계 분석 및 추세를 보간하여 기존 위성 AOD 보다 정확한 위성 AOD 자료를 생산하였다. 이후 합성과정을 진행하며 최종적으로 시공간적으로 더 완벽하고 정확한 AOD 합성장을 생산하였다. 생산된 AOD 합성장의 제곱근 평균 오차(Root Mean Square Error; RMSE)는 0.13, 평균 편향(mean bias)는 0.05로, 기존의 GOCI AOD (RMSE: 0.15, Mean bias: 0.11)와 AHI AOD (RMSE: 0.15, Mean bias: 0.05) 보다 나은 성능을 보였다. 또한 합성된 AOD는 단일위성에서 구름으로 인하여 관측되지 못한 지역에서 시공간적으로 보다 완벽하게 생산되었음을 확인하였다.

In this study, fused Aerosol Optical Depth (AOD) data were produced using AOD products from the Geostationary Ocean Color Imager (GOCI) onboard Communication, Oceanography and Meteorology Satellite (COMS) satellite and the Advanced Himawari Imager (AHI) onboard Himawari-8. Since the spatial resolution and the coordinate system between the satellite sensors are different, a preprocessing was first preceded. After that, using the level 1.5 AOD dataset of AErosol RObotic NETwork (AERONET), which is ground-based observation, correlations and trends between each satellite AOD and AERONET AOD were utilized to produce more accurate satellite AOD data than the original satellite AODs. The fused AOD were found to be more accurate than the original satellite AODs. Root Mean Square Error (RMSE) and mean bias of the fused AODs were calculated to be 0.13 and 0.05, respectively. We also compared errors of the fused AODs against those of the original GOCI AOD (RMSE: 0.15, mean bias: 0.11) and the original AHI AOD (RMSE: 0.15, mean bias: 0.05). It was confirmed that the fused AODs have better spatial coverage than the original AODs in areas where there are no observations due to the presence of cloud from a single satellite.
