We are pleased to announce a new processing baseline ID for Copernicus Sentinel-3 concerning the following products:

· SLSTR L1 products SL_1_RBT

The new Processing Baseline includes:

• Inclusion of an Online Quality check parameter in SLSTR L1 product. To ease the distinction between nominal products and the ones affected by an operational anomaly, the definition of the Online Quality check parameter – included in the manifest file – has been reviewed. This parameter can now be associated with three different values: FAILED (in case of Manoeuvre, important percentage of missing data on all bands, …), DEGRADED (in case of pointing issue or inappropriate/missing VISCAL or NAVATT files) or PASSED (nominal conditions).
• Improvement of the SLSTR surface classification. This evolution is focusing on the coastline classification, considering the whole pixel field of view (FOV defined by 6 corners) acquired by SLSTR and no longer the center of the pixel. Following this modification, coastline is no longer discontinuous and is now defined as the interface between land and ocean areas but also as the interface between land and inland water pixels. Two additional parameters (count_water and count_water_orphan) have also been added in the flags_xx.nc file and are providing, for each coastline pixel, the number of FOV corners over water.

The land, ocean and inland waters classification are not impacted by this evolution. The tidal classification may be impacted over large discharges area:  some pixels inside the tidal area may be missed by the tidal classification.

The new processing baseline will be deployed on 23/04/2024 for Copernicus Sentinel-3A and Sentinel-3B.

An unexpected power outage occurred on Friday 22 March afternoon at the Svalbard ground station which significantly affected the nominal data reception capabilities for the Sentinel-1, -2, -3 and -5p satellites.

The power was restored relatively quickly, but a number of systems had been affected, requiring additional time for the stations operators to restore the nominal services.

The nominal availability of the products cascading from data acquisitions at Svalbard for these missions was critically affected in consequence, either irrecoverably, or subjected to long delays resulting due to the necessary reconfiguration work which had to be carried out at the station following the power loss.

The exhaustive list of the impacted datatakes is reported on the Copernicus Dashboard here, in association to the event reported on 22 March 2024.

It is further highlighted that the production associated to some of the delayed datatakes is still on-going and planned to be completed within the next couple of days.

We apologise for the inconvenience this may cause to your activities.

The Sentinle-3 Hydro-Cryo thematic masks, used to produce the Level-2 Thematic Data Products, are now available on SentiWiki.

The three Thematic Masks, that are Hydrology, Sea Ice and Land Ice, are used to define the coverage of the respective Thematic Products.

The Thematic Masks are available for download in tiff format.

More information is available in the dedicate sections on SentiWiki.
