摘要：
The direct measurements of size-segregated particle fluxes above a city are presented. The emission or deposition was measured directly with micrometeorological techniques, and the controlling parameters were derived by footprint analysis and by comparison with meteorological parameters. Particle fluxes were calculated from the fluctuations in the vertical wind component and number concentration, based on the eddy correlation approach.
