Model predictions of ambient PM₁₀ against the measured data in 2005. Comparison of model daily predictions of ambient PM₁₀ (μg/m³) using visibility with measured data withheld from modeling for use as validation dataset: A) superimposed to show day-to-day variation and B) as a scatter plot to show correlation (r² of 0.68, slope = 0.90). Observed PM₁₀ is included for comparison purposes only, the study used predicted PM₁₀ values only.
