Air quality and emissions monitoring data

Air quality affects health, compliance and reputation, and the data behind it is richer than ever. This guide covers air-quality and emissions monitoring data.

Available across the EU. DataSupplier sources and delivers this data in all 27 European Union countries — including Germany, France, Spain, Italy, the Netherlands and Poland — and across the EEA, in the format and cadence you need.

Why air-quality data matters

Pollution drives health outcomes, regulation and public concern. Air-quality and emissions data supports compliance, ESG, health analysis and operational decisions.

The data landscape

• Reference monitoring: official station networks.
• Satellite: regional pollutant observations (Copernicus).
• Low-cost sensors: dense local readings.
• Emissions: inventories and reporting.

Reference vs low-cost

Reference stations are accurate but sparse; low-cost sensors are dense but noisier; satellite gives broad coverage. Combining them, with calibration, gives the best picture, and understanding each accuracy is essential.

Common use cases

Health and exposure analysis, compliance and reporting, ESG and operations, and smart-city management.

Sourcing considerations

Much data is open (EEA, Copernicus, national networks), but harmonising sources and handling sensor quality is the work. Combining with location and population data adds value.

In a managed model

A managed partner can combine reference, satellite and sensor air-quality data, calibrated and documented.

Reference, satellite and low-cost sensors

Air-quality data spans accurate but sparse reference stations, broad satellite observations (Copernicus atmosphere services), and dense but noisier low-cost sensors. Each has a different accuracy and coverage profile, and the best picture combines them, with calibration, rather than relying on one. Understanding each source’s accuracy is essential before drawing health or compliance conclusions.

Harmonisation and use

Much air-quality data is open (EEA, Copernicus, national networks) but needs harmonising and combining with location and population data to support exposure, compliance, ESG and operational decisions. Provenance and method documentation matter where the data feeds regulated reporting.
