Context
The Copernicus Land Monitoring Service (CLMS) is migrating its data to the Copernicus Data Space Ecosystem (CDSE). As a result, the way CLMS products are structured and referenced on WEkEO is changing.
This transition is happening progressively. Different products are migrated at different times. Some are already available exclusively from the new source, others are still on both, and more will follow in the coming months.
The CLMS Global datasets, coordinated by JRC (NDVI, LST, SWI, Burnt Area, and more), are already fully migrated. The CLMS European datasets coordinated by EEA, such as the High Resolution Layers, Urban Atlas, and VLCC products, are currently being transitioned and will follow progressively until end of 2026.
User impact
The change is minimal. You only need to replace your old WEkEO dataset ID (e.g. EO:CLMS:DAT:CLMS_GLOBAL_NDVI_... or EO:EEA:DAT:HRL:GRA) with the new one: EO:JRC:DAT:CLMS, and replace the productType parameter with a datasetIdentifier value.
⚠️ For some products, once the data is available from the new source, it becomes unavailable from the old one immediately. Check the transition table to know the current status of your products.
Where to find your dataset identifier
Depending on your situation, use one of the two resources below.
Already using CLMS data on WEkEO?
Use the CLMS transition table on GitHub. It lists all CLMS products with their old and new identifiers side by side. The "Current" sheet shows old dataset IDs and their new equivalents where available. The "New" sheet lists all products already available from CDSE, and whether the old source is still active.
If your product isn't in the table yet, it hasn't been migrated, your existing queries will continue to work in the meantime.
Looking for a product to use?
Refer to the CDSE CLMS documentation for the full catalogue of available products and theirdatasetIdentifiervalues.
How to download data step by step
Step 1: Find your dataset identifier
Open the CDSE CLMS documentation
Locate your product in the table and copy the value from the Dataset column, this is your
datasetIdentifier(e.g.lc_global_100m_yearly_v3)You can check the additional details provided in the table, such as: Product Type, Time Coverage, Spatial Coverage, Resolution, Frequency
📌 Note: The "Product Type" column is shown for informational purposes, you don't need it for your query. The dataset identifier alone is sufficient.
Step 2: Download via the WEkEO Viewer
Open the WEkEO Viewer and search for
EO:JRC:DAT:CLMSClick on “Add to map”, then click on the download button in the layer window. If you are not already logged in, sign in to your WEkEO account.
Enter your dataset identifier in the "Dataset Identifier" field
Set your date range, time range, and spatial extent as needed
Click "Request data" to download
💡 WEkEO Pro Tip: Click "Show API Request" in the viewer to generate a ready-to-use query for Python, R, cURL, or any other HDA client.
