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.
