Title: Atmospheric aerosol mass concentration and scattering coefficient in a midlake region
Abstract: Abstract The relationship between aerosol mass concentration ( M ) and scattering coefficient ( B scat ) in urban and rural land-based environments has been well documented. In this study, comparison of M and B scat in the mid-Lake Michigan region has revealed a linear regression line B scat = (0.298 ± 0.036) + (0.0138 ± 0.0029) M with correlation coefficient 0.97. The slope of this regression is substantially less than the values reported previously in land-based settings. This difference is accounted for by the midlake aerosol size distribution, which exhibits a distinctly greater number concentration of secondary aerosols as measured by an active scattering aerosol spectrometer. The integrating nephelometer is confirmed to be a good instrument for in situ measurement of mass concentration. However, the slope of the linear regression line between M and B scat is dependent on the ambient aerosol size distribution and, therefore, on the sampling environment.
