WRAP Regional Haze Air Quality and Visibility Modeling Results



Air quality and visibility modeling results are organized into 3 tables below. Table 1 includes CMAQ results for the 2002 model performance evaluation (MPE) case and results for the 2002 Planning Case and the 2018 Base Case. Table 2 includes results for the CAMx MPE case and the PSAT source apportionment simulations. Table 3 includes other model sensitivity studies. Older model results (e.g., preliminary evaluation and test cases) are listed below in the archive section.
