eLTER provides researchers with access to over >200 eLTER Sites and >50 larger eLTSER Platforms in terrestrial, freshwater and transitional water ecosystems across biogeographical regions in Europe in a whole-system approach. It offers long-term time series over up to 100 years, harmonised and standardised data, services and training useful to citizens and experts in investigating ecosystem processes and finding sustainable solutions to the Grand Societal Challenges like climate change, unsustainable use of resources, pollution and eutrophication. eLTER catalyzes scientific discovery and insights through its state-of-the-art research infrastructure, collaborative working culture, and transdisciplinary expertise.
Start year of datasets: Measurements/data date back 2-3 decades in most cases (partly up to a century). The eLTER standardized protocols have started to be applied since about 5 years and will be quantitatively applied from 2027 onwards.
