Retrieval of Chlorophyll-a in Lower Reaches of the Minjiang River Via Three-Band Bio-Optical Model
Chlorophyll-a (Chla) can intuitively reflect the degree of eutrophication of water, Chla concentration can be accurately estimated via the three-band bio-optical model because it can weaken the influence of factors such as suspended and yellow matter in case-II waters. Therefore, the approximate position of the three-band factor was determined by analyzing the spectral characteristics of the measured water body. Further, three characteristic bands and a retrieval model were established using the exhaustive method and correlation analysis. Results show that when λ1=661.63 nm, λ2=693.54 nm, and λ3=757.35 nm, the three-band factor [
