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 GEO and optically more complex waters of GOCI swath area, we developed new BRDF, atmospheric correction and bio-optical algorithms for GOCI. The GOCI calibration and validation effort includes spacecraft, atmospheric, sea surface, subsurface plus laboratory and data analysis components which require pre- and post-launch activities. 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 and Central Yellow Sea buoys and in situ measurements. Although this presentation is centered on GOCI , the approach is applicable to any ocean color mission.
