A seven-year-based characterization of aerosol light scattering properties at a rural central European site
Result description
Our study investigates the temporal variability of aerosol light scattering properties measured at three wave- lengths (total scattering coefficient, backscattering coefficient, Ångstr¨om scattering exponent, hemispheric backscattering ratio and asymmetry parameter) at the rural background site of the National Atmospheric Ob- servatory Koˇsetice over a period of over seven years (2012–2019). The influence of fog and cloudiness on aerosol light scattering properties (ASP), together with their comparison to particle number size distribution was also investigated. The overall medians of total scattering (σsp) and backscattering coefficient (σbsp), hemispheric backscattering ratio (b) and asymmetry parameter (g) measured at 550 nm and Ångstr¨om scattering exponent (SAE_450/700) were 35.20 Mm 1, 5.07 Mm 1, 0.14 and 0.57 and 1.82, respectively. σsp and g decreased by 2.05 Mm 1/year, and 0.009/year, respectively, whereas b increased by 0.004/year. The selected aerosol properties were strongly correlated with particle number, mass, area and volume concentrations in the 200–800 nm mode.
