From:Atmospheric Chemistry and Physics (Vol. 20, Issue 5) Peer-ReviewedDiurnal variation of surface PM.sub.2.5 concentration (diurnal PM.sub.2.5) could dramatically affect aerosol radiative and health impacts and can also well reflect the physical and chemical mechanisms of air pollution...

From:Atmospheric Chemistry and Physics (Vol. 21, Issue 11) Peer-ReviewedDifferent types of pollution boundary layer structures form via the coupling of different synoptic systems and local mesoscale circulation in the boundary layer; this coupling contributes toward the formation and...

From:Atmospheric Chemistry and Physics (Vol. 18, Issue 5) Peer-ReviewedOver the past decades, Beijing, the capital city of China, has encountered increasingly frequent persistent haze events (PHE). While the increased pollutant emissions are considered as the most important...

From:Atmospheric Chemistry and Physics (Vol. 19, Issue 10) Peer-Reviewed
We investigated the interactions between the air pollutants and the structure of the urban boundary layer (UBL) over Beijing by using the data mainly obtained from the 325 m meteorological tower and a Doppler...

From:Atmospheric Chemistry and Physics (Vol. 20, Issue 16) Peer-ReviewedAerosols cause cooling at the surface by reducing shortwave radiation, while urbanization causes warming by altering the surface albedo and releasing anthropogenic heat. The combined effect of the two phenomena needs to...
