Urban Atmospheric Science

Programme overview

The Urban Atmospheric Science programme aimed to generate new knowledge and predictive capacity of key environmental processes governing the distribution, transport, and transformation of atmospheric pollutants in urban areas, informed by, and informing, research in pollutant exposure and risk to human health.

Background & objectives

Assessing the risk of air pollution to people in urban areas, developing policies to protect them, and monitoring the effects of these policies is difficult because it is hard to understand and predict how pollutants behave in the urban environment. Some reasons for this include lack of understanding of basic processes governing pollutant concentration and distribution in the urban atmosphere, how the urban atmosphere interacts with the overlying boundary layer, how this might be altered by changes in climate and the built environment itself, and how all this impacts on human health.

The programme aimed to:

  • Improve measurements and monitoring of the distribution of pollutants and pathogens at required time and space scales.
  • Improve knowledge of processes and models of the dynamics of transport and transformation of pollutants and pathogens in the environment.
  • Improve assessments of pollutant and pathogen exposure and risk to humans.
