New datasets family published in CDS: Copernicus pan-Arctic regional reanalysis (CARRA2)

We are pleased to announce that the first batch of the second-generation Copernicus Arctic Regional Reanalysis called Copernicus pan-Arctic Regional Reanalysis (CARRA2) datasets have been published in the Climate Data Store (CDS) on 10-12-2025:

The CARRA2 datasets include:

  • All 4 level types (single, model, height and pressure level) in the same entry;
  • Spatial subsetting option to avoid the need to download large files;
  • Sub-daily and daily/monthly data available in separate entries.

This first data batch includes 24 years of intermittent data. The full 40 years (1986-2025) will be ready in mid-2026.

For any enquiries regarding this dataset or the application, please contact us.
