Abstract
GOCI, the first Geostationary Ocean Color Imager, shall be operated in a staring-frame capture mode onboard its Communication Ocean and Meteorological Satellite (COMS) and tentatively scheduled for launch in 2010. The mission concept includes eight visible-to-near-infrared bands, 0.5 km pixel resolution, and a coverage region of 2,500 × 2,500 km2 centered at Korea. The GOCI is expected to provide SeaWiFS quality observations for a single study area with imaging interval of 1 hour from 10 am to 5 pm. Due to optically more complex waters of GOCI swath area, we developed new atmospheric correction and bio-optical algorithms for GOCI. The 1st objective is to compare and validate the water-leaving radiance using the radiometric data from spectroradiometer installed in Ieodo and Gaegeocho ocean research station. The 2nd objective is to calibrate and validate the bio-optical product by GDPS using the Dokdo buoy and in situ measurements. As the result of comparison of spectrum shape using the remote reflectance normalized 555 nm, most of all data was well matched. Validation result of local bio-optical algorithms installed in GDPS showed the less than 20 %.
