New dataset published in CDS: Arctic regional reanalysis daily and monthly data from 1991 to present

We are pleased to announce that a new dataset of the Copernicus Arctic Regional Reanalysis (CARRA) family has been published on 02 October 2025, in the Climate Data Store (CDS):

Arctic regional reanalysis daily and monthly data from 1991 to present

This new entry includes daily and monthly data of CARRA including means, extremes and some totals. The new data will complement the existing four CARRA catalogue entries in a new single entry, which includes all level types.

Please be aware that very soon the first batch of the brand new Copernicus pan-Arctic Regional Reanalysis (CARRA2), which will have extended spatial and temporal coverage compared to the present CARRA data, will be also published on the CDS. Follow the C3S announcement section for the release news on this new data.
