The optical contribution of submicron particles after 1 µm filtration. a Ratio of particle size distributions measured after and before filtration of 5-m water samples through a 1-µm filter as a function of the particle diameter (D, units of µm). Each point is the median of all ratios for samples collected during the AMT26 cruise (N = 22; Supplementary Fig. 1) for a given particle diameter. Red dashed lines represent the first and third quartiles. b Boxplot for the corresponding 1µm-to-bulk ratios of cp and bbp coefficients at 532 nm. The thick black line indicates the median value. Upper and lower side of each box are the third and first quartiles, respectively. Vertical bars represent minimum and maximum values. Open circles are outliers
