A 3D study on the amplification of regional haze and particle growth by local emissions

npj Climate and Atmospheric Science, 2021
The role of new particle formation (NPF) events and their contribution to haze formation through subsequent growth in polluted megacities is still controversial. To improve the understanding of the sources, meteorological conditions, and chemistry behind

Cloud‐Surface Coupling Alters the Morning Transition From Stable to Unstable Boundary Layer

Geophysical Research Letters, 2023
Due to surface heating, the morning boundary layer transits from stable to neutral or convective conditions, exerting critical influences on low tropospheric thermodynamics.

Sulfate formation is dominated by manganese-catalyzed oxidation of SO2 on aerosol surfaces during haze events

Nature Communications, 2021
Sulfate aerosols are an important component of wintertime haze events in China, but their production mechanisms are not well known. Here, the authors show that transition metal-catalyzed oxidation of SO2 on aerosol surfaces could be the dominant sulfate ...
