ECO-MOSAIC will provide harmonised climate–biodiversity datasets and derived indicators designed for reuse by scientists, conservation practitioners, and policy users. Core inputs include ESA Climate Change Initiative (CCI) Essential Climate Variable products (e.g. land cover, biomass, soil moisture, fire, land surface temperature, permafrost), multi-mission Earth Observation data (Sentinel-1/2/3, Landsat archive, Earth Observation campaign data, AIRS), and climate reanalyses and projections (Copernicus ERA5 and CMIP6).
Biodiversity and ecosystem data will comprise species occurrence records (e.g., GBIF), vegetation plot information (European Vegetation Archive), and other monitoring datasets, such as LUCAS and EVA, complemented by field plots and citizen science data in the case studies.
Products will span scales from 10–60 m (Sentinel-2 derived variables and high-resolution maps) up to km-scale CCI climate and land products, with temporal coverage from the 1980s (Landsat) to present, and revisit intervals of days to months depending on the sensor. All inputs will be regrided, rescaled, and quality-filtered to a common spatial and temporal reference grid suitable for pan-European analyses.
Data will be delivered in open, analysis-ready formats (e.g. NetCDF, GeoTIFF/Cloud-Optimised GeoTIFF and STAC/ARCO-compliant collections), with rich metadata, versioning and persistent identifiers to support traceability and FAIR use via a cloud-based repository. A “Technical Note on Data Tailoring” and a “How-to-use” user guide will document processing chains, uncertainty treatment and recommended use cases.
Validation is a core component of ECO-MOSAIC. Dedicated product-validation activities will include uncertainty analysis for each dataset, propagation of errors through rescaling and modelling steps, and cross-comparison with independent reference products and field data for the three case studies.
