Practical guide
Compare air-quality measurements
Compare the same pollutant, averaging period and verification status.
Choose the appropriate series
Select Romania and pollutant. Use E1a for annually verified series and explicitly label recent E2a data as unverified.
Air quality measurement time series ↗Retain station metadata
Record station, period, unit and averaging duration. Report coverage and missing values before calculating a mean.
Air quality measurement time series ↗Add geographical context
Land cover can provide context at the product’s scale. A 2018 product does not automatically describe the current surroundings of a station.
CORINE land cover 2018 ↗
A pitfall to avoid
A station reading does not describe every resident’s exposure. This path supports research, not medical recommendations or real-time alerts.
What you can produce
A comparison stating pollutant, stations, interval, observation coverage and verification status.
