Additional information

The geographical coverage is the 38 EEA member countries, but only complete time series are included in the analysis. The selected time series are aggregated to European level by averaging across all sites for each year.

Two time series are shown – a longer time series representing fewer water bodies and a shorter time series representing more water bodies.
