Details
Overview
The Copernicus Climate Change Service (C3S) is the European Union’s official climate intelligence service, operated by ECMWF. It provides free, open access to high-quality climate data, projections and indicators that cities can use to understand current and future climate risks.
Key Features
- ERA5 Reanalysis: Hourly estimates of climate variables from 1940 to present at ~31 km resolution globally
- Climate projections: CMIP6-based multi-model ensembles with RCP/SSP scenarios to 2100
- Climate indicators: Pre-computed urban-relevant metrics (cooling degree days, heat wave frequency, extreme precipitation)
- Climate Data Store (CDS): API access and an interactive toolbox for custom data exploration
Who Is It For?
Climate scientists, municipal planners and researchers who need reliable baseline and future climate data for vulnerability assessments, infrastructure design or policy analysis.
