The pan-European eLTER network connects around 250 long-term sites that monitor changes in climate, biodiversity and land use. Until now, this data has often been collected using different methods, with different time periods and spatial resolutions. This made comparisons difficult and slowed down the analysis of long-term trends. The new concept now defines key ecosystem variables and standardised protocols that enable reliable analysis. At the centre is a holistic approach that considers the atmosphere, water, soil and biological systems together. This systemic view is a prerequisite for better understanding complex interactions and developing reliable forecasts. Experience from almost two decades of operating the TERENO research infrastructure has been incorporated into the development and gives the model operational depth. This means a qualitative leap for research. Data becomes more consistent, usable over decades and across locations. At the same time, the concept strengthens co-operation between institutions and creates a basis for evidence-based environmental policy. This turns many individual measuring points into a coherent picture that can significantly advance Europe's environmental research.
