Source Sector and Fuel Contributions

Estimates of source sector and fuel contributions to ambient PM2.5 at SPARTAN sites are provided based on McDuffie et al. (2021). These estimates were produced from chemical transport model simulations (GEOS-Chem) and high-resolution satellite-derived PM2.5 concentration estimates, with SPARTAN data used for evaluation.
