| Abstract: | The models of retrieving chlorophyll (Chl) concentrations, together with the basic process of SeaWiFS imagery, are introduced. A simple solution was proposed to retrieve SeaWiF invalid data in highly turbid waters in Pearl River estuary (case 2 waters). Finally, chlorophyll (Chl) concentrations in Pearl River estuary are extracted by using corrected SeaWiFS data. The results show the mean standard error is 29.6% between the retrieved values and in situ data. |
