# Focus on cities

These applications provide air quality information specifically for European cities, including pollutant concentrations, population exposure and comparative assessments of urban air quality.

## Air quality in cities

* - ### Population exposed to air pollution

    Analyse the proportion of the urban population exposed to NO₂, O₃, PM₂.₅ and PM₁₀ concentrations above selected European air quality standards.

## European city air quality viewer

```{list-table}
:widths: 60 40
:class: viewer-list-table

* - ### European city air quality viewer

    Compare more than 700 European cities according to long-term exposure to PM₂.₅, NO₂ and O₃. The ranking is based on population-weighted concentrations derived from high-resolution air quality maps together with concentration-response functions recommended by the World Health Organization.

    This application was previously known as the **City Ranking Viewer**.
