Abstract
The 2nd Geostationary Ocean Color Imager (GOCI-II) is a GOCI follow-on instrument designed by the Korea Ocean Satellite Center of KIOST. GOCI-II acquires ten daytime observations of the Northeast Asian Sea with 12 spectral bands and 300 m/pixel spatial resolution. Atmospheric correction is a fundamental process for ocean color imagery to remove the atmospheric effect from the top-of-atmosphere level. The GOCI-II atmospheric correction algorithm is essentially a revision of the previous GOCI algorithm and partially improved for the turbid water NIR correction. The turbid water NIR correction uses an iterative optimization between water and aerosol reflectance model at 620, 709, 745, and 865 nm wavelengths. This GOCI-II atmospheric correction system is vicariously calibrated by the previous GOCI data during the overlapped period. Initial atmospheric correction results are verified and validated by both the GOCI and in-situ remote-sensing reflectance datasets.
