Abstract

The chlorophyll-a concentration is one of important index for the water environment. Based on the measured chlorophyll-a concentration, water spectral data and FY-3A moderate resolution imaging spectrometer data, the feasibility of using FY-3A to monitor the chlorophyll-a concentration in Zhanjiang Bay and its adjacent waters was researched. The results show that the waters of the Zhanjiang Bay is close to case one water, and case two water is mainly distributed in the narrow and enclosed area near the Zhanjiang Harbour; and the OC4 algorithm can be used to monitor the remote sensing of the chlorophyll-a concentration in the Zhanjiang Bay. The measured chlorophyll-a concentration has good correlation with the retrieved one, and the correlation coefficient R is better than 0.7. FY-3A medium resolution imaging spectrometer data can reflect the distribution of chlorophyll-a concentration in Zhanjiang Bay.
