EEA Air Quality Viewer

The European Environment Agency (EEA) published on 4 April an online viewer that tracks the weekly average concentrations of nitrogen dioxide (NO₂) and particulate matter (PM10 and PM2.5). This is in response to the COVID-19 pandemic and has been developed to assess how it has affected concentrations of air pollution.

The EEA viewer, along with information on the methodology used, can be found at:
