Cover Story: Particle number size distributions have been measured in Rochester, NY since 2002, along with PM2.5, black carbon, and pollutant gases. Obvious features such as the morning rush hour and afternoon regional nucleation events can be identified. However, assessing the particle sources requires the applications positive matrix factorization to the seasonal data from winter, summer, and the transitional seasons. From 2002 to 2016, there were substantial changes in particle emissions and formation rates due to the implementation of multiple policies related to cleaner fuels, additional controls on vehicles, and reduced emissions from coal-fired power plants. Those coal combustion reductions came from reduced electricity demand during the 2008 recession and the change in the relative prices of coal and natural gas. View this paper.
