From: The open-ocean missing backscattering is in the structural complexity of particles
Beam attenuation and backscattering coefficients detect particles of similar sizes. Cumulative percent contributions (units of %) for modelled particulate beam attenuation (a) and optical backscattering (b) coefficients at 532 nm, as a function of the particle diameter (D, units of µm). Black solid line indicates the median value and red areas represent the standard deviation obtained using the selected coated-sphere parameterisations. Vertical rectangles correspond to the median ± 1 standard deviation of the size thresholds of particle diameters causing 10%, 50%, and 90% of the signal, from left to right of each plot, respectively. This analysis is based on data collected during the AMT26 cruise at the ocean surface (5 m) and at the DCM level
