The Copernicus Atmosphere Monitoring Service (CAMS) is continually monitoring air quality in Europe and around the world using satellite and ground-based observations and advanced numerical models. The page provides access to graphical products and animations, as well as some answers to questions related to CAMS products and their relevance in the context of the COVID-19 crisis. The maps of daily average surface polluants (N02, PM10) featured on the page are complemented by time series starting 1 February 2020 and by animations of hourly variations of the polluants over the last month. The page also explains why N02 and PM10 are especially relevant in the context of COVID-19, and what the differences between CAMS analyses and satellite images are, for instance from the Sentinel-5P.
