Problems with ERA5 ancillary data

[nicola.ghirardi]

Hi everyone,

I’ve encountered an issue with requesting ERA5 ancillary data.
Until August 2024, the procedure described in the GitHub README worked fine but has since stopped functioning. The following link is now inactive: "https://cds.climate.copernicus.eu/api-how-to".

I discovered that ECMWF data has migrated to a new portal, so I updated the CDS API key with the new required information (https://forum.ecmwf.int/t/step-by-step- ... -beta/3743).
However, after updating the credentials, I tried running POLYMER again (using two different accounts and credentials), but it still doesn’t seem to work.

The error message is:
"requests.exceptions.HTTPError: 403 Client Error: Forbidden for url: https://api.ecmwf.int/v1/retrieve/v1/pr ... gle-levels"

Does anyone know how to resolve this issue?
Thanks in advance!
