Air quality data (data stream E1a) — Validated single values 2021 (dataset)

Data stream E1a includes measured (link to data stream D) individual values of gaseous pollutants (e.g. ozone, nitrogen dixoid, sulphur dioxide, carbon monoxide), particulate pollutants (e.g. particulate matter, soot, total dust) and dust constituents (e.g. heavy metals, PAHs in PM10, PM2.5, TSP) and the total deposition (BULK), wet deposition and meteorological measurements (e.g. temperature, wind speed, air pressure) for which a data provision obligation exists. The report also includes the data quality objectives (measurement uncertainty, minimum time coverage meets yes/no, minimum data capture meets yes/no) and information on concentration values is attributed to natural sources and application of stray sand and salt (concentration values without any correction deductions).
