🌿 Webinar: Computing Leaf Area Index with Sentinel-2 in EOPF Zarr format

Esther Millet — Mon, 09 Mar 2026 10:35:27 +0000

Join our upcoming 45-minute webinar exploring how Leaf Area Index (LAI) can be retrieved from Sentinel-2 data in the EOPF Zarr format. The session will demonstrate how cloud-native EO data structures enable efficient and scalable analysis of vegetation dynamics across large time series.

Using a real use case over South Tyrol (2023), the webinar will showcase a practical workflow for analysing vegetation indicators using Sentinel-2 data stored in EOPF Zarr format.

During the session you will:
🔹 Learn how LAI can be retrieved from Sentinel-2 observations
🔹 Discover scalable cloud-native processing workflows with EOPF Zarr data
🔹 Follow a hands-on demonstration analysing vegetation dynamics over time
🔹 Explore applications for environmental monitoring and vegetation analysis

This webinar is part of the EOPF webinar series, supporting early adopters working with the new EOPF Zarr data products.
