Caeli featured in De Telegraaf: Air Quality Monitor and new satellites
On August 7, 2025, Caeli was featured on the science page of Dutch newspaper De Telegraaf in an article about how we make air quality visible at street level.
Air Quality Monitor: combining satellite and ground data
With our Air Quality Monitor (AQM), we combine satellite observations, ground-based measurements and our own machine learning models. This provides municipalities, provinces and other organisations with real-time and historical data on NO₂ and particulate matter, down to neighbourhood and street level.
This enables policymakers to make better-informed decisions and monitor the impact of air pollution on public health more effectively.
A new generation of monitoring
The article also highlights the launch of new satellites, such as Sentinel-4, which will further improve the resolution and reliability of air quality data.
Together with the European Space Agency (ESA), we are helping build the next generation of air quality monitoring: more accurate, more accessible and increasingly valuable for policymakers and researchers.
More and more cities are joining
Cities such as Almere, Deventer, Kampen, Hilversum and Tallinn are already using our insights. An increasing number of municipalities are joining to help create healthier and more liveable environments.
