We are pleased to announce that the new version (v2) of the Copernicus Interactive Climate Atlas (C3S Atlas) dataset and viewer has been published on 07-05-2025.
- Gridded dataset underpinning the Copernicus Interactive Climate Atlas
- Copernicus Interactive Climate Atlas Viewer
The new version of the dataset includes many new data sources and variables such as:
- Additional observation-based data sources; Berkeley Earth Foundation dataset (BERKEARTH) for temperature, NOAA Climate Prediction Center dataset (CPC) for precipitation and the European Space Agency (ESA) SST Climate Change Initiative (CCI) dataset (SSTSAT) for sea surface temperature.
- Regional reanalysis for Europe (CERRA: Copernicus European Regional Reanalysis).
- SSP1-1.9 scenario for the CMIP6 models.
- New bias adjusted variables for temperature and precipitation threshold indices.
- Updated and improved drought indices.
- Several new extreme climate indices.
For more details, please check the relevant documentation.
The new version of the viewer includes some new features such as:
- New selector for bias adjusted variables
- Ensemble granularity information for climate projections in regional products (ability to distinguish and subselect climate models)
- New regional selection of mega cities
- Summary table, monitoring and urban heat island information in the regional plots
For more details, please check the relevant documentation.
Finally, please also note that new C3S Atlas User Tools are also available:
These tools provide Jupyter Notebook examples about the computation of some of the C3S Atlas climate indices and also how some of the visual products are prepared.
