Annual layers of European Ecosystem land units (ELU) from 2000 to 2018 at 100 m are provided. Ecosystems, in this context are defined as intersections between macroclimatic conditions, landform, land cover and areal extent. The thematic legend of land cover is consistent with European Ecosystem Accounting, with the layers providing auxiliary information. Further, the underlying land cover time series is fully consistent with the Corine Accounting standard.
