And there will be a second webinar!
Join us for the second session of the ESA EOPF Sentinel Zarr Samples webinar series on 24 April 2025 at 2:00 PM (CEST). This series is designed to support a wide range of users in adopting the new EOPF Zarr data format.
In this edition, @annefou will take a deep dive into the Sentinel-2 L2A Zarr format, demonstrating how it enables faster and more scalable Earth observation data workflows.

The S3 we use at work has a quota on the number of files, which makes zipped Zarr attractive to us. However reading from a Zarr-Python’s ZipStore that uses a local or S3 zipped Zarr takes about 3x time compared to Zarr in the same storage. I implemented an async read-only fsspec file system to read from a given zip file and reading from a FsspecStore using the file system made local/S3 zipped Zarr as fast as Zarr.
