Products
To help you tackle air pollution and climate-related problems, we offer several products that deliver clear insights.
Air Quality Monitor
See how air quality changes per neighbourhood and back choices for a healthier living environment. Ground stations do not cover every neighbourhood. AQM fills that gap with satellite observations validated against ground measurements, so you see NO₂, particulate matter and other indicators across the whole area. Down to neighbourhood level, available as maps and time series in the dashboard and via the API.

Carbon Eye
See per location whether reported CO₂ emissions match what satellites measure. Emission inventories and internal estimates are often incomplete or delayed. Carbon Eye compares reported CO₂ with satellite observations so you can see where claim and measurement diverge per asset or location, including outside local monitoring networks.

Nitrogen module
Track how ammonia develops around your area and back measures with measurements. Measurements in the area show how the ammonia concentration develops, set against the background. A learning model combines those measurements with satellite data. Deposition in the area itself remains an estimate from that model, checked against measured concentrations.

Approach
Outside the monitoring network you often miss the places that matter. Caeli makes air quality and emissions visible with satellite data, AI and ground-station validation.
From satellite to district and neighbourhood, sharpened with AI and land use. Also outside the monitoring network.
Checked against more than 5,000 reference stations across Europe, so maps and time series stay traceable for policy and reporting.
In our dashboard and products we bring several pollutants together, so you have insight into air quality everywhere.

Martin Smit recently appeared on the DMI Doet podcast. In an engaging conversation with Jan-Willem Wesselink, he explains how Caeli uses artificial intelligence (AI) and satellite data to map air quality in cities in greater detail and with increased accuracy.
Caeli is joining the NWO (KIC)-funded EO-TRUST research project as a partner. Together with academic, government and industry partners, Caeli will help develop a secure, reliable and independent European Earth observation infrastructure, supported by a €1 million impact grant.
Municipalities that want a clear picture of local air quality often run into the limitations of the national monitoring network. For Helmond, the nearest representative monitoring stations for substances such as NO₂ and particulate matter are in Eindhoven or Vredepeel. Ultimately, these stations are too far from Helmond itself to provide meaningful local insights. Since 2023, the municipality has been addressing this gap with an additional data source: monthly satellite measurements of air quality, combined with ground-based measurements and a purpose-built AI model.
