Abstract
Phytoplankton carbon in marine environment is one of the important factors for ecosystem and climate change. Using satellite-based primary production, which is mainly influenced by the sun light energy, especially photosynthetically available radiation (PAR), phytoplankton carbon at the ocean surface can be estimated. In this study, daily PAR is induced by GOCI, the world first geostationary ocean color observation satellite and validated. 6 months of validation dataset has been collected at two ocean research stations,Socheong-cho and Ieodo. Socheng-cho station is located at Yellow sea nearby Socheong Island and Ieodo station is located 149 kilometers southwest of Mara Island. On the clear sky condition, GOCI daily PARs showed relatively high accuracies, while they showed lower accuracies on the cloudy sky condition than on the clear sky condition.The future study will be dealing with modification of GOCI-derived daily PAR model using two station’s in-situ data.le radiation (PAR), phytoplankton carbon at the ocean surface can be estimated.
