@Anabelle FYI, the link to this forum post on the CDS doesn’t work: if I open it on the homepage, it tries to send me to `https://cds.climate.copernicus.eu/[https:/status.ecmwf.int](https:/forum.ecmwf.int/t/cc-by-licence-to-replace-licence-to-use-copernicus-products-on-02-july-2025/13464)`; if I open it from a catalogue entry, e.g. `https://cds.climate.copernicus.eu/datasets/reanalysis-era5-single-levels`, it sends me to `https://cds.climate.copernicus.eu/datasets/[https:/status.ecmwf.int](https:/forum.ecmwf.int/t/cc-by-licence-to-replace-licence-to-use-copernicus-products-on-02-july-2025/13464)`, etc. ---

Hi @Olivier_Burggraaff Thank you for reporting this. Link should be fixed (works for me now) - you might need to refresh the page 🙂 ---

no wonder the downloading process for Multilevel product in ADS seems to be stuck when selecting the Model Level. The selections turned to grey color after the level 60. and the downloaded data did not come in dataset even after set for both downloading Pressure Level and Model Level. Do we have to change something in the .cdsapirc like last time migration?? ---

It’s great to see that the licensing has been unified under the Creative Commons Attribution (CC-BY) license. However, I noticed that the STAC metadata for some datasets still reflects the older licenses. For example: - [ERA5 Complete Reanalysis](https://cds.climate.copernicus.eu/datasets/reanalysis-era5-complete?tab=overview) — [STAC metadata](https://cds.climate.copernicus.eu/api/catalogue/v1/collections/reanalysis-era5-complete) - [Satellite Soil Moisture](https://cds.climate.copernicus.eu/datasets/satellite-soil-moisture?tab=overview) — [STAC metadata](https://cds.climate.copernicus.eu/api/catalogue/v1/collections/satellite-soil-moisture) It would be very helpful if the STAC metadata could be updated accordingly to reflect the current licensing. Thank you! ---

Hi Angelika, Thanks for your feedback 🙂 With respect to the STAC metadata, I’m not seeing what you are seeing for the 2 datasets you listed. Could you clarify, please. Many thanks!
