Fig. 5. Comparison of measured dry PM_2.5 (particles with aerodynamic diameters less than 2.5 µm) particle scattering (bspg) based on uncorrected front-filter organic carbon (OC) with (a) particle scattering reconstructed from the Elastic Light Scattering Interactive Efficiencies (ELSIE) model and (b) particle scattering (bsp) based on Grand Canyon Visibility Transport Commission (GCVTC) scattering efficiencies (outlier excluded from regression).
