Determining coefficients in a reconstructed aerosol concentrations model from observed visibility.
A model reconstructing aerosol loading from observed visibility was proposed by Rosenfeld et al. in 2007, and it has been adopted by many researchers. The validity of original coefficients of this model was examined by a correlation analysis between visibility and PM10 concentration. The results showed that the coefficients in this model are not applicable in the region studied and they needed to be adjusted. Optimized coefficients were determined using several approaches in this study. The authors suggest that the methodology put forward by this paper would be meaningful for not only the reconstruction of long-term aerosol concentration data but also the application of the model proposed by Rosenfeld et al.
