한국 연안수의 시간적 동역학을 위한 GOCI

Abstract

Geostationary Ocean Color Imager (GOCI), the world’s first geostationary ocean color observation satellite, can be effectively used to monitor the temporal dynamics of the turbidity of coastal waters because it can obtain satellite image every hour during the daytime. we estimated real movements of ocean surface currents using the high temporal resolution of GOCI in the Korean coastal water. Ocean surface currents were deduced from multiple ocean color scenes derived from GOCI images of two types, total suspended matter (TSM) and chlorophyll concentration (CHL). TSM scenes were exploited to estimate fast currents in highly turbid coastal waters, and CHL scenes were employed for relatively clear waters. The results showed that the ocean surface currents estimated by the proposed algorithm well represent the dynamic movements of surface water around the Korean Peninsula.very hour during the daytime. we estimated real movements of ocean surface currents using the high temporal resolution of GOCI in the Korean coastal water.
