Users are informed of a ground segment anomaly occurred on 21st February evening and resolved on 22nd February morning impacting the generation of several Copernicus Sentinel-2A products from sensing orbit 29608 to 29619 and several Copernicus Sentinel-2B products from sensing orbit 20701 to 20710.

Due to a ground segment anomaly in processing, the Sentinel-5P SO2 Near Real Time (NRTI) data products from orbits 17345 up to including 17353 on 17th February 2021, have reduced quality.

Due to an issue that occurred at PDGS level, the Near Real Time Copernicus Sentinel-3 OLC, SLSTR and SRAL Level 1 and Level 2 products starting from around sensing time 22:30:00 UTC on 16 February to 06:00:00 UTC on 17 February will be delayed.

We are pleased to announce the publication of three handbooks related to Sentinel-3 OLCI, SLSTR and Synergy land products.

The nominal Sentinel-1 production rate has been restored and all products are nominally available for user data access.


ESA invites you to take part in the continuous improvement process by providing feedback related to your experience of accessing and using EO data and related information and services from the Copernicus Sentinel Missions during 2020.

Infrastructure security maintenance activities are scheduled on the Data Hubs on:

  • Tuesday 16 and Wednesday 17 February
  • Tuesday 23 and Wednesday 24 February

Due to an issue that occurred at Ground Segment level, the Near Real Time , Short Time Critical and Non Time Critical Copernicus Sentinel-3A OLC, SLSTR and SRAL Level 1 and Level2 products (including S3A/S3B SYN NTC/STC data) starting from sensing time 11-02-2021T14:05:00 UT to 15:46:00 UT (orbit 25979) will be missed.

As a consequence of a wrong calibration parameter in the ground segment activated in the night between 10 and 11 February, the Copernicus Sentinel-2A L1C and L2A production systematically failed up to the roll-back to the previous ground segment configuration finalised in mid-morning today. The impact is from Sentinel-2A sensing orbit 29457 to 29461.

As a consequence of maintenance activity executed on the Copernicus Sentinel-3B spacecraft on 03/02 from UTC time 07:55 to 08:29, reduced data quality for all the SRAL related user products should be expected for data sensed during this period.
