Aerosol retrieval over urban cities

摘要

In order to understand the atmospheric constituents over the urban area, the aerosol properties obtained from radiometry with AERONET are compared with the suspended particulate matter (SPM) simultaneously measured with a new instrument (SPM-613D). It is found that the SPM measurements classified as fine particles (PM2.5) and coarse particles (TSP/PM10) are very useful for determining the dominating of particle size and air quality. There was a strong correlation between the PM2.5 concentration and aerosol index (AI). It indicates that aerosol characteristics can be estimated from SPM data, and vice versa.
