Following the transition of Sentinel-3A into routine operations and following the news published on 19 October 2017, the production of the SAR Radar Altimeter (SRAL) instrument will no longer be published on the Sentinel-3 Pre-Operations Data Hub starting Monday, 15 January 2018.

Infrastructure maintenance activities on the data hubs are scheduled to take place on 10 and 11 January.
Due to a Sentinel-3A ground segment anomaly on 03 January 2018, data related to orbit #9785 to orbit #9789 are delayed.

Due to a Sentinel-3A antenna anomaly on 01 January 2018, data related to orbit #9760 are missing.

Monitoring large, remote bodies of water is logistically challenging, time consuming and expensive. Responding quickly to events that pose a risk to human health has been almost impossible, given the size of some lakes and seas. An innovative satellite data service is now able to change things around.

The anomaly that affected the OLCI instrument aboard Sentinel-3A has now been resolved.
Due to an OLCI Instrument anomaly on 19 December 2017 at 01:44 UTC, data is either degraded or unavailable until further notice.
At an event held on 13 December at ESA's Headquarters in Paris, France, an Understanding for the Sentinel Collaborative Ground Segment Cooperation was signed to facilitate Sentinel data exploitation in Romania.
A new version of the Sentinel-2A spectral response functions has been released.
Following the announcement earlier today, the anomaly affecting the Sentinel-3A ground segment has now been resolved.
