Large contribution of fossil - fuel derived secondary organic 1 carbon to water - soluble organic aerosols in winter haze of China
19 Water-soluble organic carbon (WSOC) is a large fraction of organic aerosols (OA) globally and 20 has significant impacts on climate and human health. The sources of WSOC remain very 21 uncertain in polluted regions. Here we present a quantitative source apportionment of WSOC 22 isolated from aerosols in China using radiocarbon (C) and offline high-resolution time-of23 flight aerosol mass spe...
متن کاملSources and light absorption of water-soluble organic carbon aerosols in the outflow from northern China
High loadings of anthropogenic carbonaceous aerosols in Chinese air influence the air quality for over one billion people and impact the regional climate. A large fraction (17–80 %) of this aerosol carbon is water-soluble, promoting cloud formation and thus climate cooling. Recent findings, however, suggest that water-soluble carbonaceous aerosols also absorb sunlight, bringing additional direc...
متن کاملContribution of dissolved organic matter to submicron water- soluble organic aerosols in the marine boundary layer over the eastern equatorial Pacific
Stable carbon isotopic compositions of water-soluble organic carbon (WSOC) and organic molecular markers were measured to investigate the relative contributions of the sea-surface sources to the water-soluble 15 fraction of submicron organic aerosols collected over the eastern equatorial Pacific during the Tropical Ocean tRoposphere Exchange of Reactive halogens and Oxygenated VOCs (TORERO)/KA-...
متن کاملMolecular composition of the water-soluble fraction of atmospheric carbonaceous aerosols collected during ACE-Asia
[1] During the Asian Pacific Regional Aerosol Characterization Experiment (ACE-Asia), samples of carbonaceous aerosols were collected on board the Center for Interdisciplinary Remotely Piloted Aircraft Studies (CIRPAS) De Havilland DHC-6 Twin Otter aircraft. The samples were analyzed to determine their total carbon (TC) and water-soluble organic compound (WSOC) contents as well as to identify t...
متن کاملDistribution of dicarboxylic acids and carbon isotopic ratios in aerosols from 1997 Indonesian forest fires
Fine aerosol particles collected in Southeast Asia during 1997 Indonesian forest fires were studied for the concentrations of total carbon (TC), water-soluble organic carbon (WSOC) and low molecular weight dicarboxylic acids (C2-C12) as well as carbon isotopic ratios of TC (δCTC). TC and WSOC showed a large increase during the heavy forest fire event. At the same period, dicarboxylic acids, dom...
