## 6. Stacked Bar Charts

The following section provides stacked bar charts comparing observed fine particulate matter composition and modeled fine particulate matter composition. Stacked bar charts have been developed for each of the STN monitoring sites in and near the Kentucky PM 2.5 

### nonattainment areas (APCD/Barret, Southwick, Covington, and Ashland).

The stacked bar chart allows a side-by-side comparison of each day’s observed and modeled compositional and total light extinction. Within each bar, the yellow portion of the bar represents the mass due to sulfates (SO4), the red portion of the bar represents the mass due to nitrates (NO3), the green portion of the bar repr esents the mass due to organic carbon (OC), the black the bar represents the portion of mass due to elemental (EC), and finally the grey portion of the bar represents the mass due to ammonium (NH4 ). The components are presented in the same order for both the observed (left hand bar) and mode led bar (right hand bar), so it is easy to identify days when the predicted mass for the co mponent differs from the observed. The total height of the bar provides th e total reconstructed mass of fine particulate matter.

Just glancing through the stacked ba rs charts reiterates that sulfates are a large contributor to

total PM 2.5 

### mass in both nonattainment areas. The bar ch arts also suggest that organic carbon is also a large contributor to PM 2.5 

### mass in the nonattainment areas. The bar charts reiterate the general under-prediction s een in previous sections . The bar charts show that the sulfate mass is generally well captured, with inst ances of both over and under pred iction. Nitrates tend to be over predicted in the early spring and late winter , when the mass is the highest. The bars also suggest that organic carb on is generally under predicted at both sites. Looking across the bars, it appears as though this under prediction of organic carbon and the slight su lfates is the largest contributor to general PM 2.5 

### under prediction.
