Natural and anthropogenic particles over East Asia

Both natural and anthropogenic aerosols are emitted to the atmosphere. The increase in anthropogenic aerosol emissions in East Asia associated with rapid economic growth combined with the complex behavior of natural dusts makes predicting aerosol distribution in this region extremely difficult. Therefore, detailed investigation of atmospheric particles is important. In this study, the characteristics of aerosols over East Asia were investigated using a combination of ground measurements and model simulations. Ground measurement data was collected using a sunphotometer supported by NASA/AERONET (aerosol robotics network) and a suspended particulate matter (SPM) sampler. In addition to altering the radiation budget, aerosols may also affect cloud cover and precipitation, which, in turn, influence the emission of natural aerosols. Thus, model simulations were utilized to investigate the influence of these changes on natural dust loading.
