Abstract

This chapter introduces the importance of air pollution on regional and global scales and explores how changes on these larger scales influence local air quality. It starts by considering the concept of global air quality, which reflects the relatively well-mixed contributions of long-lived pollutants present in the global atmosphere, and then explores the differing characteristics of regional scale pollution in different parts of the world. Long-range transport of pollutants in the atmosphere provides a mechanism that links air quality in different regions, such that they are not independent of each other. The chapter then explores the historical and likely future changes in air quality at regional and global scales and highlights the implications that this may have for local air quality.
