The Reno Aerosol Optics Study: An evaluation of aerosol absorption measurement methods [PDF]

, 2005
The Reno Aerosol Optics Study (RAOS) was designed and conducted to compare the performance of many existing and new instruments for the in situ measurement of aerosol optical properties with a focus on the determination of aerosol light absorption. For

Size-resolved particle number emissions in Beijing determined from measured particle size distributions [PDF]

Atmospheric Chemistry and Physics, 2020
The climate and air quality effects of aerosol particles depend on the number and size of the particles. In urban environments, a large fraction of aerosol particles originates from anthropogenic emissions.

Aerosol modeling over Europe: 2. Interannual variability of aerosol shortwave direct radiative forcing [PDF]

, 2007
Aerosol distribution over Europe and its direct radiative forcing have been simulated with a regional atmosphere-chemistry model and an off-line radiation transfer model. Primary and secondary organic and inorganic aerosols have been considered.

Dust emission reduction enhanced gas-to-particle conversion of ammonia in the North China Plain

Nature Communications, 2022
Liu et al. found that the formation rate of particulate ammonium is slower in the atmosphere than that observed in the laboratory, while it is sped up due to an increase in aerosol acidity driven by an emission reduction of dust in North China Plain.
