Since the Sentinel-3 mission entered operations, the satellites have occasionally experienced anomalies or events that impact the quality and availability of the mission's data.
Download the anomalies and events report to see the details of each event affecting OLCI. A glossary of terms is also available.
The dates of the events are summarised in the following yearly calendars. For each calendar day, if an event occurred:
- Tagged with 'A' - events affecting only Sentinel-3A
- Tagged with 'B' - events affecting only Sentinel-3B
- Nothing is displayed when it affects Sentinel-3A and Sentinel-3B
- If two events occurred, the two colours are displayed in the cell
Please consult the Product Notices related to each instrument.
