Fig. 3. Parameters of the Red Sea two-component bio-optical model: (a) chlorophyll-specific particulate absorption coefficients (ap) as a function of wavelength, (b) chlorophyll-specific
particulate backscattering coefficients (bbp) as a function of wavelength and the background backscattering component (bbp
k ), and (c) chlorophyll-specific CDOM absorption coefficients
(ag) as a function of wavelength for the two assemblages (A1 and A2). Figures d–f show the relationship between ap(443) and C, bbp(443) and C, and ag(443) and C respectively, for the Tara
data and the fitted model.
