Study finds wind concentrates pollutants with unexpected order in an urban environment

Green Car Congress

A new study has found that pollutant particles carried by these flows prefer to accumulate in specific regions of the urban environment and even form coherent structures, rather than scattering randomly. It was not known if such structures were robust enough to manifest in the environment.

Peking University team develops method for modeling historical global black carbon emissions from motor vehicles with reduced uncertainty

Green Car Congress

Researchers at Peking University have developed a new methodology to model black carbon (BC) emissions from diesel and gasoline motor vehicles. Black carbon is a key short-lived climate change forcer ( earlier post ) and motor vehicles are important sources of BC in the environment. Credit: ACS, Wang et al. Streets, D.
