Estimation of phytoplankton primary productivity in qinghai lake using ocean color satellite data: seasonal and interannual variations

HIGHLIGHTS

• What: This approach has the advantages of high temporal resolution (revisit period of 1 day), numerous effective data points, and wider coverage than other satellite data . This study attempts to develop an improved VGPM model applicable to Qinghai Lake using OC products and in situ observational data, and applies this model to estimate chlorophyll-a and PP levels during the non-freezing period of Qinghai Lake over 20 years. In this study, the survey data from 2018 to 2023 (mainly including chlorophyll-a concentration (Copt ) and surface water temperature (T)) were compared with the spatiotemporal synchronized data . . .
