From: The open-ocean missing backscattering is in the structural complexity of particles
Mie theory cannot simultaneously reproduce beam attenuation and backscattering coefficients. Modelled vs. measured particulate beam attenuation (a, c) and optical backscattering (b, d) coefficients at 532 nm. Comparisons are based on data collected at the ocean surface (5 m) and at the DCM level during the AMT26 cruise. a and b indicate model results with refractive index n equal to 1.06; c and d for n equal to 1.11. Systematic error (Bias), Pearson’s correlation coefficient (r) and number of observations (N) are shown. All r coefficients are statistically significant (p < 0.01). Error bars (black vertical lines within each point) represent the combined uncertainty (95% confidence intervals) as propagated from particle size distribution measurements (see Methods)
