dc.description.abstract | Geostationary Ocean Color Imager (GOCI) records the total radiance exiting the top-of-atmosphere (TOA) at 6 visible bands (centered at 412, 443, 490, 555, 660, and 680nm) and 2 near-infrared (NIR) bands (centered at 745 and 865nm) bands with a moderate spatial resolution and a high temporal frequency. The current GOCI standard atmospheric correction method that is included in the GDPS ver.1.3 is theoretically based on the SeaWiFS/MODIS standard approach (Gordon and Wang, 1994), however, its implementation is partially different (Ahn et al., 2012 Ahn et al., 2015).In this study, we describes the updated atmospheric correction schemes for GDPS ver.1.4 including 1) water vapor absorption correction, 2) sun-glint correction, 3) modified white-cap correction, 4) modified Rayleigh scattering correction, and 5) correlated adjustments of vicarious gains and turbid water NIR correction model coefficients. These scheme updates significantly impact on the oligotrophic region of GOCI observation.h a moderate spatial resolution and a high temporal frequency.
