Service update: Oceanographic wave analysis with Sentinel-2 Zarr data
This new Jupyter notebook showcases an improved workflow for wave spectral analysis in oceanography by moving from the traditional Sentinel-2 SAFE format to the cloud-optimised EOPF Zarr format. The transition streamlines data access, boosts computational efficiency and enables scalable analyses. Through practical steps, the notebook demonstrates how to:
- Access Sentinel-2 data in Zarr format via STAC and xarray
- Ensure detector consistency and apply image normalisation and filtering
- Perform 2D Fourier and cross-spectral analysis for wave characterisation
- Compute viewing geometry metrics and interpret results with spectrum plots, coherence maps and phase differences
By simplifying preprocessing and enhancing analysis capabilities, this workflow makes Sentinel-2 data more accessible for advanced oceanographic applications.
Each notebook can now be started instantly using the launch button included in all rendered notebooks.
EOPF open source plugins: GDAL EOPF-Zarr Plugin v2.0.0
This release brings a powerful GDAL driver for accessing EOPF Sentinel Zarr Samples, with seamless QGIS integration, automatic CRS and geotransform detection, and improved metadata handling.
It’s cloud-native (HTTP/HTTPS, VSI support), cross-platform (Linux, macOS, Windows), and comes with a ready-to-use Docker image including GDAL 3.10.2, Rasterio and JupyterLab.
Webinars
We’ve now reached the seventh session in our webinar series on adopting the new EOPF Zarr data format. Each edition builds on previous insights, providing practical guidance and expert perspectives tailored to diverse user needs.
Webinar #7: EOPF Zarr data access with openEO and STAC
Join us for a practical introduction to accessing and processing EOPF Zarr products through the openEO API, a unified interface that makes Earth observation workflows more standardised, portable and reproducible. This 45-minute session will guide participants through:
- Accessing EOPF Zarr data with openEO
- Creating customised virtual data cubes
- Running simple processing workflows
Designed for beginner to intermediate users, the webinar will also share the latest updates on the Sentinels EOPF Sample Service and support the growing community of early adopters.

EOPF Zarr Hackathon: from exploration to optimisation in cloud-native Earth observation
As a side event of BiDS25, in collaboration with the EOPF Toolkit project, the EOPF Zarr hackathon invites participants, from newcomers to experts, to dive into the Earth Observation Processing Framework using cloud-native formats like Zarr, STAC, Dask and Julia.
The event tackles real-world challenges across the Copernicus Sentinel missions, fostering collaboration and innovation around topics such as chunking strategies, DGGS, GeoZarr, CF conventions and more. A full-day tutorial on EOPF tools and technologies will be held in advance.
