Context
Some Sentinel and Copernicus Monitoring Land Service (CLMS) datasets are affected by a change on their access method on provider's side. WEkEO is adjusting the Harmonised Data Access (HDA) to fetch them. Those changes can have an impact on your search queries.
⚠️ Action required starting from Tuesday, 24 February 2026, 18:00 CET: If you have existing HDA queries targeting the below-listed datasets, you may need to update them. Some query parameters have been renamed, some are no longer supported, and some new parameters are now available (see tables below).
Concerned datasets

Update queries
If your existing HDA query contains parameters that have been renamed, simply replace the old parameter name with the new one.
For example, for a Sentinel-1 query:
Before:
{
"dataset_id": "EO:ESA:DAT:SENTINEL-1",
"platform": "S1A",
"polarisation": "VV",
"startdate": "2024-01-01T00:00:00.000Z",
"enddate": "2024-01-31T23:59:59.999Z"
}
After:
{
"dataset_id": "EO:ESA:DAT:SENTINEL-1",
"platformSerialIdentifier": "S1A",
"polarisationChannels": "VV",
"startdate": "2024-01-01T00:00:00.000Z",
"enddate": "2024-01-31T23:59:59.999Z"
}
If your query uses a parameter that is no longer supported, simply remove it from your query. If that parameter was critical to your workflow, please contact the WEkEO User Support for guidance.
💡WEkEO Pro Tip: in any case, we highly recommend to use the Expert Data Viewer to build the query to use directly the correct parameters.
