Access and explore Zarr sample products
Browse available S1, S2, and S3 datasets, access them via cloud tools, and extend your workflow with open-source plugins.
STAC catalogue browser
Search, filter, and preview all available EOPF products. Also available programmatically via pystac-client.
A robust framework for data analysis and computation
As part of the Sample Service, the EOPF Analytics Hub gives you a ready-made environment for working with EOPF Zarr data — no local setup required.
The notebook gallery is the starting point for putting it to use, with each notebook opening directly in JupyterHub, ready to run on Dask.
JupyterHub
Pre-configured JupyterLab environments with EOPF plugins already installed, plus a set of interactive notebooks to get started right away.
Dask
Parallel, data-proximate computing that runs next to the data itself, so you can process large Sentinel products without downloading them. Tightly integrated with JupyterHub.
Access to the Analytics Hub uses your Copernicus Data Space Ecosystem (CDSE) identity. It's also accessible through the STAC Browser or programmatically via Python, Julia, and more.

Work in the cloud via JupyterHub when possible. Since Zarr's chunked format is designed for lazy remote access, direct download is not recommended.
