Mixing state, spatial distribution, sources and photochemical enhancement to sulfate formation of black carbon particles in the Arctic Ocean during summer Open
Black carbon heats the atmosphere by absorbing solar radiation and regulates the radiation balance of the Earth. Specifically in the Arctic region, black carbon accelerates Arctic warming by simultaneously altering surface albedo. Nonethel…

Stable Mercury Isotopes Revealing Photochemical Processes in the Marine Boundary Layer Open
The marine boundary layer (MBL) is an important transportation and reaction zone of atmospheric mercury on Earth. However, the transformation mechanisms of Hg in the MBL remain unclear. In this study, total suspended particle samples were …

Spatial and Temporal Distribution of Sea Salt Aerosol Mass Concentrations in the Marine Boundary Layer From the Arctic to the Antarctic Open
Global warming, increases in sea surface temperatures (SST), and reductions in sea ice may lead to changes in the distribution of global sea salt aerosol (SSA) concentrations, which may in turn affect the global climate. However, there are…

Atmospheric Δ <sup>17</sup> O(NO <sub>3</sub> <sup>−</sup> ) reveals nocturnal chemistry dominates nitrate production in Beijing haze Open
The rapid mass increase of atmospheric nitrate is a critical driving force for the occurrence of fine-particle pollution (referred to as haze hereafter) in Beijing. However, the exact mechanisms for this rapid increase of nitrate mass have…
