Sentinel-4 will monitor Europe's air quality hourly

The Copernicus Sentinel-4 mission will provide hourly air quality data over Europe, a significant advancement for forecasting and public health. This data will help track pollution patterns. Sentinel-4, positioned in geostationary orbit, will monitor pollutants like nitrogen dioxide and ozone. This allows for continuous observation and near real-time data distribution, unlike previous missions. The mission is a collaboration between ESA and Eumetsat, and is part of a global network of air quality sensors. The data will be used for forecasts, health warnings, and environmental policy.
