On 05-3-2020 we announced that due to a technical issue on the CORDEX, access to download CORDEX regional climate model data on single levels for Europe from the Climate Data Store was temporally disabled.
Now the the download is reopened. Most of the requests are currently being completed successfully but some of them may unpredictability fail. In this case, we ask users to try again later. The CDS team continues to investigate the issue until full access is restored.
Thank you for your patience.
