Mineral dust particles suspended in the atmosphere span more than three orders of magnitude in diameter, from <0.1 µm to more than 100 µm. This wide size range makes dust a unique aerosol species with the ability to interact with many aspects of the Earth system, including radiation, clouds, hydrology, atmospheric chemistry, and biogeochemistry. Th...

Air pollution is exacerbated in cities, where pollution sources are numerous and located in a restrained area. Paved surfaces represent more than 40% of urban areas [Akbari et al., 2003], but the impact of asphalt surfaces on urban air quality has been overlooked. Although road abrasion particulate matter (PM) emissions have been well documented, a...
