Journal ArticleDOI
Markedly enhanced absorption and direct radiative forcing of black carbon under polluted urban environments
Jianfei Peng,Min Hu,Song Guo,Zhuofei Du,Jing Zheng,Dongjie Shang,Misti L. Zamora,Limin Zeng,Min Shao,Yusheng Wu,Jun Zheng,Yuan Wang,Crystal R. Glen,Don R. Collins,Mario J. Molina,Renyi Zhang,Renyi Zhang +16 more
TL;DR: The results indicate that BC under polluted urban environments could contribute significantly to both pollution development and large positive radiative forcing, implying that reduction of BC emissions under polluted environments achieves a cobenefit in simultaneously controlling air pollution and protecting climate, especially for developing countries.
Journal ArticleDOI

TL;DR: Investigation of new particle formation in Shanghai found that the observed concentration of sulfuric acid was high enough to explain the particle growth to ~3 nanometers under the very high condensation sink, whereas the subsequent higher growth rate beyond this size is believed to result from the added contribution of condensing organic species.
Journal ArticleDOI
Atmospheric nanoparticles formed from heterogeneous reactions of organics
TL;DR: In this article, exposure of nanoparticles to organic vapours shows that various organic species can enhance the growth of the nanoparticles, which is a key component of atmospheric aerosols, growing rapidly under ambient conditions.
Journal ArticleDOI
Formation of nanoparticles of blue haze enhanced by anthropogenic pollution
TL;DR: The results suggest that initial growth from the critical nucleus to the detectable size of 2–3 nm most likely occurs by condensation of sulfuric acid and water, implying that anthropogenic sulfur emissions strongly influence formation of terrestrial biogenic particles and exert larger direct and indirect climate forcing than previously recognized.

TL;DR: In this paper, the MI-LAGRO field campaign in Mexico City used a high resolution AMS spectra to identify a biomass burning organic aerosol component, which includes several large plumes that appear to be from forest fires within the region.
