India – Air Pollution Knowledge Assessment (APnA) city program


Air Pollution knowledge AssessmentsInformation and data are prerequisites for an effective Air Quality Management (AQM) plan. This means having information on (a) what is the level of pollution (monitoring trends) (b) which areas are the most polluted (spatial trends) (c) who is contributing to this pollution (source trends) (d) when do pollution levels peak (temporal trends) and (e) what are the options we have to reduce pollution (control trends). This involves creating a detailed information database that includes pulling together data from disparate sources, surveys, mapping and atmospheric modeling. Deciding on policy options based on this information and implementing them effectively is the next step.

The APnA “Air Pollution Knowledge Assessment” city program is designed to provide a starting point for understanding air pollution and present a clear picture of the state of air pollution in Indian cities.
