In Great River Bluffs, the average PM2.5 mass
concentration during 6/2002-8/2003 is 9 µg/m3, and the average total light
extinction coefficient (Bext) is 82 Mm-1 (Visual Range ~ 48 Km; Deciview ~
21). Sulfate and nitrate are two of the largest contributors to haze, with
an average contribution of 40% and 28%, respectively. Figure 2 indicates
sulfate is the biggest contributor to haze in the warm season, and nitrate
is the biggest in the cool season. |
