This article presents a method for real- time mapping of algal blooms in turbid coastal waters using the remote sensing reflectance of red band (Channel 1, 580-680 nm) and near-infrared band (Channel 2, 720-1100 nm) of the AVHRR sensor on the NOAA series satellites. A turbidity-free function for near-infrared and red signals, α0 = (bb(1)/bb(2))(a(2)/ a(1)) based on the first order bb/(a+bb) model deducing equation Rrs(2)-1 =α0 Rrs(1)-1+ g-1 (1-α0), were selected as a chlorophyll-a related index for detecting algal blooms, and the algal blooms with chlorophyll-a concentration of 64-256 mg/L could be defined by window of 1.6
