The relationship between the numerical of Sauter mean diameter (SMD) and aerosol distribution parameters, as well as its physical significance are lacking in detailed research. Meanwhile, existing method is not widely used for SMD accurate measurement due to many restrictions on the incident light wavelengths. In this study, we analyzed the relationship between SMDs and the mean and median values of the lognormal, normal, and Weibull distributions with different parameters. It is found that SMD can be directly used to substitute the mean particle size in lognormal distributions with slight deviations. A new method for aerosol SMD measurement with no wavelength limitation based on the light scattering response of the combined volume-surface area of particles is proposed. SMD inversion results show that this method reduces the error caused by inconsistent integration of the wavelength of incident light and particle size in existing measurements, because has no limitation on the wavelength of incident light. SMDs of N-Heptane combustion smokes measured using the developed sensor indicates that our proposed SMD measurement method effectively compensates the shortcomings of the existing method and improves the measurement accuracy, with the minimum and average errors of 8.9% and 14.78%, respectively.
