In WARI1, the average PM2.5 mass
concentration during 7/2003-12/2003 is 5.7
mg/m3, and the average total light extinction coefficient
(Bext) is 24 Mm-1 (Visual Range ~ 163 Km; Deciview ~
9). OMC and CM are the largest contributors to haze, with an average
contribution of 23% and 18%, respectively. Figure 2 indicates that OMC
contributes 20-30% to haze all-around the year. CM contributes ~20% to haze
from July to October, and nitrate contributes ~15% in November and December.
