The concentration of fine aerosol particles measured at a specific site can be represented as the sum of the contributions from local emissions and those from transport processes active at increasing spatial scales (Lenschow et al., 2001).

Abstract
The concentration of fine aerosol particles measured at a specific site can be represented as the sum of the contributions from local emissions and those from transport processes active at increasing spatial scales (Lenschow et al., 2001). The discrimination of such components is probably the most important information that is required when implementing air policy measures at the local (urban) scale. To this aim, the permanent networks of stations for PM2.5 monitoring at urban and rural sites can be coupled to more sophisticated analyses performed on a field campaign basis, to gain a deeper understanding of the physical and chemical mechanisms responsible for the formation and evolution of background particles.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
