Further to our previous announcement of 22 March 2021,we are pleased to confirm the operational deployment of the geometric refinement for Copernicus Sentinel-2 products on 30 March 2021.

As a consequence of maintenance activity executed on the Copernicus Sentinel-3A spacecraft on 17/03 from UTC time 07:01 to 07:37, reduced data quality for all the SRAL related user products should be expected for data sensed during this period. Reduced data quality for SLSTR user products can be moreover expected from approximately 06:51 to 11:06.

As of 23 February 2021, the processing of Copernicus Sentinel-1 L1 and L2 products, tagged as NRT-3h and Fast24h, have been aligned.

A ground segment production issue occurred on the evening of 19 March and was resolved on the morning of 20 March.

We are pleased to announce the upcoming start of the geometric refinement for Copernicus Sentinel-2 products. The goal of this evolution is to improve the multi-temporal co-registration and the absolute geolocation accuracy of the products, by using a Global Reference Image (GRI) as source of Ground Control Points (GCPs) to constrain the geometric model of the images.

Following the announcement on 8 March, please note that:

Due to an issue occurring at PDGS level, the Near Real Time Copernicus Sentinel-3 SRAL NRT and STC Level 1 and Level 2 products starting from approximate sensing time 18:28 UTC on 18 March 2021 will be missed or delayed.

As a consequence of a contingency held at ground network level, the nominal availability of Copernicus Sentinel-2 Level-2A products was prevented on 13 March.

The monitoring of frozen river break-ups at high latitudes is a daunting task, where hazards such as flooding and infrastructure damage can occur in mere days and are difficult to forecast— the monitoring from space of how river ice break-ups unfold and progress could help mitigation efforts, create data for reanalysis and aid hazard assessments.

Following popular demand from the Sentinel-3 user community, ESA are now providing Copernicus Sentinel-3 SLSTR Level 3 composite products for the Land Surface Temperature (LST) Level 2 products. Daily and monthly composites are provided.
