Air quality data (data stream E1a) - Validated individual values 2020 (data set)

Data stream E1a comprises measured (link to data stream D) individual values of gaseous pollutants (e.g. ozone, nitrogen dixide, 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) as well as total deposition (BULK), wet deposition and meteorological parameters (e.g. temperature, wind speed, air pressure), for which data provision is mandatory. The report also includes the data quality objectives (measurement uncertainty, time coverage meets yes/no, data capture meets yes/no) and information on concentration values attributable to natural sources and the spreading of sand and salt (concentration values without any correction deductions).
