Source-resolved variability of fine particulate matter and human exposure in an urban area

Source Code for PMCAMx-v2.0: High-resolution modeling of fine particulate matter in an urban area using PMCAMx-v2.0 Brian T. Dinkelacker, Pablo Garcia Rivera, Ioannis Kioutsioukis, Peter Adams, and Spyros N. Pandis

Short summary
The contribution of various pollution sources to the variability of fine PM in an urban area was examined using as an example the city of Pittsburgh. Biomass burning aerosol shows the largest variability during the winter with local maxima within the city and in the suburbs. During both periods the largest contributing source to the average PM2.5 is particles from outside the modeling domain. The average population-weighted PM2.5 concentration does not change significantly with resolution.
