Collaborative users are informed that Access Node-3 of the Collaborative Data Hub Service has not been accessible for search and download from 14 May 2019 at 23:06 UTC to 15 May 2019 at 6:26 UTC. Investigation on the root cause is on going.
Node-1 and Node-2 were not affected by the anomaly and have published and delivered products nominally.
The service has been restored to its nominal operations.
We apologise for the inconvenience caused to your activities.

Due to a ground segment anomaly, Copernicus Sentinel-2 Level-2A products with sensing time between 00:46:48 UTC on 6 May and 10:06:28 UTC on 9 May are affected by degraded quality on the image radiometry.
The whole set of impacted L2A products will be removed from all datahubs and the corresponding products will be regenerated and disseminated to users in the coming days.
We will update you once the recovery has been completed.

A routine decontamination activity of the Copernicus Sentinel-2B MSI is planned to take place over a continuous period of 24-hours between 20 May 2019 12:00 and 21 May 2019 12:00 UTC (corresponding approximately to the period between absolute orbits 11503 to 11517). During this temporal window no MSI acquisition will take place.
Correlated calibration activities will be performed around the decontamination period that will further affect the nominal acquisition plan between 20 May 2019 00:50 and 22 May 2019 08:30 UTC.

We are pleased to publish the fourth Sentinel Data Access Annual Report. This report for 2018 follows directly on from the 2017 report, and analyses the uptake of Copernicus Sentinel data and the performance of the Sentinel Data Access System during the period from 1 December 2017 to 30 November 2018.

By the end of the reporting period, the Sentinel Data Access System was supporting 187,800 registered users, a daily publication rate of over 26,500 products/day, and an average daily download volume of 166 TiB. A total of 122.9 million products had been downloaded by users since the start of data access operations, with a total data volume of 86.9 PiB. The report provides the detailed statistics behind these numbers, as well as examining the demographics of users, the status of agreements with collaborative and international partners, the challenges and solutions found by the Data Access Operations team in publishing and disseminating such huge volumes of data, and the outlook for the future.

The 2018 Copernicus Sentinel Data Access Annual Report is available here.

Due to a Ground Segment anomaly Copernicus Sentinel-3A data belonging to the orbit 16654, corresponding to the sensing time window 2019-04-29 15:01:00 UTC to 2019-04-29 16:41:00 UTC, are missing.

The issue impacts all data from all instruments.

On 6 May 2019, a new Processing Baseline (02.12) will be deployed for the Copernicus Sentinel-2 Level-2A products.

This new Processing Baseline features the following change:

• Improvement of the terrain correction algorithm, in order to avoid adjacent tile discontinuities in terrain correction for seemingly flat areas with gentle slopes.
  

Processing Baseline 02.12 remains compliant with the current version of the Product Specification Document (PSD v14.5).

Due to an issue occurred at Ground Segment level on 27 April 2019, following Near Real Time Copernicus Sentinel-3A data related to orbit 16623 have been missed:

• SLSTR from 20190427T10:54:25 UTC to 20190427T12:34:25 UTC
  
• SRAL from 20190427T10:53:42 UTC to 20190427T12:34:25 UTC
  
• OLC from 20190427T10:52:23 UTC to 20190427T11:36:44 UTC.
  

Short Term Critical an Non Time Critical data are available.

The Copernicus Sentinel-1A and -1B satellites have been restored to nominal operations on 18 April at 15:00 and at 15:50 UTC, respectively.

In summary, the operations unavailability periods were:

• Sentinel-1A: from 00:45 to 15:00 UTC on 18 April
  
• Sentinel-1B: from 23:55 UTC on 17 April to 15:50 UTC on 18 April
  

No SAR data were generated during these periods.

Copernicus Sentinel-1A and -1B are currently unavailable since 18 April at 00:45 UTC and 17 April at 23:55 UTC, respectively, following an issue in the execution of orbit control manoeuvres.

Recovery actions have started and are expected to take about half a day, indicatively.

Further news will be released once operations are resumed.

The Copernicus Sentinel-2B acquisition on 12 April with sensing time between 00:55:08 and 00:56:06 - relevant to orbit 10953 - has been lost due to a collision avoidance manoeuvre executed between 11 April at 23:21:36 and 12 April at 01:20:34 UTC.

We apologise for any inconvenience this may cause to your activity.

Collaborative users are informed that on Wednesday 17 April 2019, a maintenance activity will be performed on Access Node-1.
The maintenance will start at 07:00 UTC and will end at 15:00 UTC.
The Collaborative Data Hub Node 2 and Node 3 will continue to be accessible to their registered users.
We apologise for the inconvenience this will cause to your activities.

Due to an issue at Ground Segment level on 5 April 2019, the following Near Real Time/Short Time Critical and Non Time critical Copernicus Sentinel-3A data have been missed:

• SLSTR from 20190405T12:04:47 UTC to 20190405T12:38:14 UTC (gap propagated to entire SYN chain)
  
• SRAL from 20190405T12:04:47 UTC to 20190405T12:29:45 UTC
  
• OLCI from 20190405T12:04:47 UTC to 20190405T12:14:43 UTC.

Users are informed that all Copernicus Sentinel-2A products relevant to orbit 19751 with sensing time between 06:50:06 and 07:52:24 UTC on 4 April are affected by a considerable geolocation inaccuracy due to a collision avoidance manoeuvre executed between 06:23:05 and 08:22:17 UTC.
The whole set of L1C and L2A products impacted by degraded quality will be removed from all datahubs in the next days.

Collaborative users are informed that Access Node-1 of the Collaborative Data Hub Service has not been accessible for search and download from 01:15 to 2:30 UTC of 5 April 2019 because of an infrastructure anomaly.
Node-2 and Node-3 were not affected by the anomaly and have published and delivered products nominally.
The service has been restored to its nominal operations.
We apologise for the inconvenience caused to your activities.

ESA is pleased to announce the publication of commissioning data on the Collaborative Data Hub, covering a gap on users' hub, following the official release of Copernicus Sentinel 3B Synthetic Aperture Radar Altimeter (SRAL) products on December 2018.

SR_1_SRA and SR_2_LAN products with sensing time window 11/05/2018 - 10/11/2018 have been published on the 21st of March.

The publication of corresponding SR_1_SRA_A_ and SR_1_SRA_BS will follow as soon as possible.
The reference Processing Baseline is the 1.17.

Users are informed that our core data hub centre has experienced a network incident on 27 March 2019 between 10:10 and 11:00 UTC.
As a result, the following dissemination services were unreachable:

• Open Access Hub (including API Hub, Sentinel-3 PreOps and GNSS Rinex PreOps)
  
• Copernicus Services Data Hub
  
• Collaborative Data Hub Node 1
  

While our services are now back to nominal operation, the root cause of the incident is still under investigation.
We apologize for the inconvenience this may have caused.

ESA is pleased to announce the official release of the Copernicus SYNERGY Sentinel-3A and Sentinel-3B products on Collaborative Data Hub Node1 Node2 Node3.
Copernicus Sentinel-3A and Sentinel-3B Synergy products will be published on Collaborative Data Hubs from 25 March 2019.

The transition from the Copernicus Sentinel-3 Pre-operations Hub to Collaborative Data Hub Node1, includes the publication of the NTC historical data belonging to the Collection Baseline 002 (Copernicus Sentinel 3 Synergy Product Notice), that corresponds to Processing Baseline n. 2.44 for Sentinel 3A and n. 1.16 for Sentinel 3B.

The NTC historical data will be gradually put online in parallel to the fresh data production only on Collaborative Data Hub Node1

The Copernicus Sentinel-3 Pre-Operations Hub will continue to publish fresh data until completion of the transition of the NTC historical dataset on Collaborative Data Hub Node1.

Please be aware that in the applicable Processing Baseline it has been introduced a change in the Normalised Difference Vegetation Index (NDVI) and this impacts products generated since the 16/01/2019: the previous NDVI range [-0.612; 0.408] has been modified into the new one [-0.08; 0.92]. The Quicklook Generator on Data Hub will be updated to take into account this change as soon as possible.

Users are informed that as a side effect of the infrastructure maintenance extension to the 21 March, the publication of Sentinel-2 Level-2A products is suffering unexpected delays. Corrective actions are in place that should secure a return to nominal publication performance within the next couple of hours.

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

The scheduled maintenance of the 18 and 19 of March 2019 has been extended to the 21st of March 2019.
Activities on security are foreseen causing the publication delay of Copernicus Sentinel-3 products.
We apologise for the inconvenience this may cause to your activities.

Following the collision avoidance manoeuvre, for Copernicus Sentinel-2B on 06 and 07 March, we now have a confirmed list of sensing orbits which were affected by the activity.

• Orbits fully impacted: 10437, 10439, 10440
  
• Orbits partially impacted: 10432, 10433, 10434, 10438
