xcube-eopf v0.3.0 is out
We’re excited to announce the release of xcube-eopf v0.3.0. Install it via conda/mamba or pip and start exploring the new features today.
Sentinel-3 support
xcube-eopf now provides workflows for generating 3D analysis-ready data cubes from multiple Sentinel-3 tiles. The workflow includes:
- Query tiles using the EOPF Zarr Sample Service STAC API for a given time range and spatial extent
- Group items by solar day
- Rectify data from the native 2D irregular grid to a regular grid with xcube-resampling
- Mosaic adjacent tiles into seamless daily scenes
- Stack the daily mosaics along the temporal axis to build 3D data cubes for each variable (e.g. spectral bands)
Supported products:
sentinel-3-olci-l1-efr– Level-1 top-of-atmosphere radiance from OLCIsentinel-3-olci-l2-lfr– Level-2 land and atmospheric geophysical parameters derived from OLCIsentinel-3-slstr-l2-lst– Level-2 land surface temperature from SLSTR

New notebooks
Each notebook is available online for you to explore and experiment with – a great way to deepen your understanding of EOPF’s cloud-native Earth Observation workflows.
Webinar #8: Access and process Sentinel-1 SLC & GRD in EOPF Zarr
We’ve now reached the 8th 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. Resources from the latest session are on the Webinar 7 page.
Join us for a 45-minute practical webinar introducing how to access and process Sentinel-1 IW GRD and SLC products in EOPF Zarr format, with Michele Claus (EURAC) and Dimitrios Papadakis (Evenflow). The session showcases how cloud-native technologies and open standards are transforming the way Synthetic Aperture Radar (SAR) data is stored, accessed and analysed. Through live demonstrations, you’ll:
- Explore Sentinel-1 SLC and GRD products in EOPF Zarr
- Understand the structure and key differences from the traditional SAFE format
- Apply SAR pre-processing workflows interactively
- Discover sample datasets available through the EOPF Sentinel Zarr Samples project
A live Q&A follows to answer your technical questions.

EOPF at BiDS25: Advancing Cloud-Native Earth Observation
Co-organised with the EOPF Toolkit, two hands-on sessions at BiDS25 (29–30 September, Riga) showcased the latest cloud-native tools for scalable, user-friendly analysis of EOPF Zarr Sentinel data.
The EOPF Sample Service tutorial, led by experts from thriveGEO and Brockmann Consult, introduced participants to Zarr and STAC for efficient data access and demonstrated new plugins – including the xarray EOPF backend, xcube data store, and GDAL/Julia readers – through a wildfire monitoring exercise in Sardinia.
The following day’s hackathon invited participants to develop prototype workflows using the EOPF Sentinel Zarr Samples Service, exploring applications of DGGS/HEALPix, metadata harmonisation and performance optimisation.
All results and notebooks are publicly available in the EOPF-Zarr-BiDS25 repository, reflecting the community’s commitment to open science, reproducibility and interoperability in Earth Observation.
EOPF Zarr Community Notebook Competition: Introductory Webinar
thriveGEO recently hosted an introductory webinar for the EOPF Toolkit Community Notebook Competition. The challenge invites Sentinel data users and developers to create and submit innovative Jupyter Notebooks that demonstrate cloud-native workflows using the EOPF Zarr Sample Service.
Participants have the chance to enhance their skills, contribute to the Earth observation community, and win prizes. Helpful resources, including the EOPF 101 book, are available to guide you through the process.
Community Support Platform
To support users of the new data formats, we have launched a dedicated Community Support Forum, a space to ask questions, share knowledge and collaborate. Whether you are looking for help, exchanging tips, or uploading community notebooks, the platform is here to grow a strong network of users.
