TL;DR: Global estimates of annual PM2.5 concentrations and trends for 1998-2018 are developed using advances in satellite observations, chemical transport modeling, and ground-based monitoring, identifying significant trends for eastern North America, Europe, and globally.

TL;DR: In this paper, the authors provide a comprehensive evaluation of sector and fuel-specific contributions to this disease burden across 21 regions, 204 countries, and 200 sub-national areas by integrating 24 global atmospheric chemistry-transport model sensitivity simulations, high-resolution satellite-derived PM2.5 exposure estimates, and disease-specific concentration response relationships.

TL;DR: In this paper, the authors developed and applied a methodology for monthly estimates and uncertainties during the period 1998-2019, which combines satellite retrievals of aerosol optical depth, chemical transport modeling, and ground-based measurements to allow for the characterization of seasonal and episodic exposure, as well as aid air-quality management.

TL;DR: Exposures to oxidant air pollutants but not PM2.5 were associated with an increased risk of incident asthma and eczema in children, suggesting that improving air quality may contribute to the prevention of asthma and other allergic disease in childhood and adolescence.

TL;DR: This review article surveys publicly available exposure datasets for surface PM2.5 mass concentrations over the contiguous U.S., summarizes their applications and limitations, and provides suggestions on future research needs.
