This document summarizes the PM Source Apportionment Technology (PSAT) analysis performed to trace SOx and NOx emissions leading to particulate species at WRAP region IMPROVE monitoring sites. This analysis was performed by the Regional Modeling Center.

This document summarizes the method used by the Regional Modeling Center to model the contribution of primary and secondary, natural and anthropogenic organic carbon at WRAP region IMPROVE monitoring sites. (Document under development)

This document summarizes the Weighted Emissions Potential (WEP) analysis performed by the TSS team. The WEP analysis identifies the potential for emissions source regions to impact haze constituents at WRAP region IMPROVE monitoring sites.

Positive Matrix Factorization (PMF) modeling was conducted for WRAP’s Causes of Haze Assessment. Results and documentation on this method can be found on the Causes of Haze Assessment website.
