In view of the fact that optical remote sensing can not detect the distribution of green tide distribution under cloud cover. In this paper, we focused on the monitoring of temporal and spatial distribution of green tide, and obtained the GOCI data from the middle of May to the middle of August. Based on this data, the authors acquired the range of green tide, the analysis of green tide drift, the extraction of fine cloud and the coverage of statistical cloud, and analyzed the influence of cloud cover on the monitoring of green tide and the feasibility of using satellites in geostationary orbit to carry out green tide operational monitoring from the two aspects of detecting capability and dynamic capability.
