Sentinel-4 will monitor Europe's air hourly

The Copernicus Sentinel-4 mission will provide hourly air quality data over Europe, a breakthrough for forecasting and public health. The mission, using a geostationary orbit, will monitor pollutants like nitrogen dioxide and ozone, offering unprecedented detail. This data will improve pollution tracking and enable more accurate health warnings. Sentinel-4 is part of a global effort, collaborating with other sensors to monitor air quality across continents. The data will be freely available for use in forecasting and environmental policy.
