We are pleased to announce the release of the full mission reprocessing campaign for the Sentinel-3 OLCI Level-1 products, covering the following datasets:
· OL_1_EFR
· OL_1_ERR
Sensing Period Coverage
The reprocessed data will cover the following periods:
· Sentinel-3A: 6 April 2016 to 6 May 2024
· Sentinel-3B: 9 May 2018 to 6 May 2024
Processing Baseline
This reprocessing campaign applies the Level-1 processing baseline deployed in May 2024 (Copernicus Sentinel-3 L1 Processing Baseline 3.28 released).
This same dataset is the basis for the on-going OLCI L2 re-processing announced earlier this month at https://dataspace.copernicus.eu/news/2025-3-6-launch-full-mission-reprocessing-sentinel-3-olci-level-2-land-products-baseline
Publication Timeline
The reprocessed Level-1 products will gradually become available on the Copernicus Data Space Ecosystem starting from 26 March 2025.
The entire reprocessing campaign will be published starting from 2019 to 2024 and finally covering the 2016-18. The publication is expected to be completed by Q2 2025.
Transition from Previous Collection
The deletion of products belonging to the previous baseline collection (002 and 003) will take place after the complete publication of the new baseline collection 004.
For a transitional period of a few months, both versions of the Level-1 products will remain available online to ensure a smooth transition for data users.
Stay tuned for further updates as we progress with the publication.
