Aerosol particles can strongly affect both air quality and the radiation budget of the atmosphere. Above Beijing, the capital city of China, large amounts of aerosols within the atmospheric column have caused the deterioration of local air quality and have influenced radiative forcings at both the top and the bottom of the atmosphere (BOA and TOA). Observations of aerosol radiative forcing and ...
a computer program was developed to predict the dispersion of gas pollutant in the atmosphere. this program relies on puff method, and in order to consider the wind shear effects, the program has the ability to consider the complete dynamic and unsteady atmospheric conditions. plume rise of hot pollutants due to buoyancy effects was also considered. the program has the capacity to perform the r...

*Adamowicz RF. 1979. A model for the reversible washout of sulfur dioxide, ammonia and carbon dioxide from a polluted atmosphere and the production of sulfates in raindrops. Atmos Environ 13:105-121.
Urban landscape plants are an important component of the urban ecosystem, playing a significant role in the adsorption of airborne particulates and air purification. In this study, six common landscape plants in Beijing were chosen as research subjects, and the adsorption capacities for each different plant leaf and the effects of the leaf structures for the adsorption capacities for particulat...
Particle nucleation continues to be a major topic of research. Although nucleation in polluted atmospheres may play a less important role in atmospheric and climate science than it plays in the remote atmosphere, it can still have an important influence on particle size distributions and a major impact upon airborne concentrations of nanoparticles. This paper makes an interesting contribution b...

The introduction of cloud condensation nuclei and radiative heating by sunlight-absorbing aerosols can modify the thickness and coverage of low clouds, yielding significant radiative forcing of climate. The magnitude and sign of changes in cloud coverage and depth in response to changing aerosols are impacted by turbulent dynamics of the cloudy atmosphere, but integrated measurements of aerosol...
