Which Copernicus datasets are currently available in the WEkEO catalogue?
WEkEO provides access to data from multiple Sentinel satellites (Sentinel-1, Sentinel-2, Sentinel-3, Sentinel-5P), as well as Copernicus services: CMEMS (marine), CAMS (atmosphere), C3S (climate change) and CLMS (land). The WEkEO catalogue can be browsed through the web portal.
Data can be downloaded manually from the web portal or programmatically through the Harmonised Data Access (HDA) API. This API allows you to use WEkEO datasets from any of the following services:
- Jupyter Notebooks. A guide on how to access the API using Jupyter Notebooks can be found under the public folder of the Jupyter Notebook environment
- Virtual Machines. A guide on how to use virtual machines can be found at in WEkEO knowledge base

I am trying to download data from the web portal and I obtain the following message: “The dataset cannot be queried”.
Make sure that your are logged in. Further, you might not be able to download data due to a server problem (either at WEkEO or at the data provider). We recommend you try again later. Finally, if the issue persists, please contact WEkEO Support.
