Methodology
This analysis is based on the European Air Quality data from EEA database (AIRBASE pre-2012 and Air Quality e-reporting post 2013) using validated data only. Monitoring stations are categorized by location (urban/suburban/rural) and type, with background stations analysed by area and traffic/industrial stations grouped separately. There is no outlier filtering applied but a completeness requirement of at least 75% data availability per year and more than 75% of years over the 19-year period is requested. Trend is calculated based on the Mann-Kendall test (p<0.05) with Sen-Teil slope estimation. Relative changes are estimated using 2005 baseline to minimize interannual variability effects.
