英文摘要	We designed a numerical experiment to characterize the impact of a dynamic chlorophyll-specific absorption coefficient ((Formula presented.)) on the retrieved temporal pattern of chlorophyll concentration (Chl) from ocean color (Rrs). It is found that, even for oceanic waters, without consideration of the temporal variation of (Formula presented.), Chl derived from a synthesized annual Rrs using the “standard” ocean color algorithms will generate false dynamic patterns of Chl or questionable phytoplankton phenology. For instance, for an annual Chl with spring and fall blooms, the inverted Chl from Rrs could show a delay of spring bloom by ∼1–3 weeks, along with a perceived earlier appearance of fall bloom or a false bloom during summer. These results highlight the complex relationships between Rrs (an optical property) and Chl (a biological property) in aquatic environments, in particular, the importance and necessity to characterize and understand the temporal variations of (Formula presented.). © 2020.
