2020년 2월 19일 천리안 2B호의 해양 탑재체 GOCI-II가 발사되었다. GOCI-II 기기는 이전의 GOCI 대비 여러 향상된 기능을 탑재함으로써, 에어로졸 산출 연구의 범위를 확장해주었다. 특히, 새롭게 추가된 380 nm 자외선 채널은 흡수성 에어로졸 관측의 민감도를 유의미하게 향상시키는 역할을 하였다. 본 연구에서는, GOCI-II의 380 및 412 nm 채널을 활용하여 2021년 1월부터 6월까지의 에어로졸 지수를 계산하고 이를 통해 흡수성 에어로졸을 탐지하였다. TROPOMI 에어로졸 지수와 비교한 결과 GOCI-II 에어로졸 지수는 양의 편차를 보였으나, 황사 화소에서의 에어로졸 지수는 구름 및 청천 화소와 뚜렷하게 구분할 수 있을 만큼 더 크게 나타났다. 또한 GOCI-II 에어로졸 지수가 크게 나타날 때, 지상 관측 장비에서도 흡수성 에어로졸이 우세하게 탐지되었음을 발견하였다. GOCI-II 에어로졸 지수 상위 25% 범위에 드는 자료들을 조사하자, 연구 기간 동안 지상에서 Dust 및 Moderately-absorbing fine 유형으로 확인된 자료들의 71.3%, 80.0%가 각각 여기에 속함을 확인할 수 있었다.

On 19 February 2020, the 2nd Geostationary Ocean Color Imager (GOCI-II), a maritime sensor of GEO-KOMPSAT-2B, was launched. The GOCI-II instrument expands the scope of aerosol retrieval research with its improved performance compared to the former instrument (GOCI). In particular, the newly included UV band at 380 nm plays a significant role in improving the sensitivity of GOCI-II observations to the absorbing aerosols. In this study, we calculated the aerosol index and detected absorbing aerosols from January to June 2021 using GOCI-II 380 and 412 nm channels. Compared to the TROPOMI aerosol index, the GOCI-II aerosol index showed a positive bias, but the dust pixels still could be clearly distinguished from the cloud and clear pixels. The high GOCI-II aerosol index coincided with ground-based observations indicating dust aerosols were detected. We found that 70.5% of dust and 80% of moderately-absorbing fine aerosols detected from the ground had GOCI-II aerosol indices larger than the 75th percentile through the whole study period.
