As of 8 October 2018, a new Processing Baseline (02.09) will be deployed for Sentinel-2 Level-2A products.

This new Processing Baseline features the following changes:

• Improvement of the accuracy of Scene Classification over water, urban and bare areas thanks to the usage of the Climate Change Initiative (CCI) Land Cover data.
  
• Improvement of the spatial homogeneity of surface reflectance between adjacent tiles.
  

Processing Baseline 02.09 remains compliant with the current version of the Product Specification Document (PSD v14.5).

Please note that the SNAP Software is aligned to the new Processing Baseline as well.

Due to a Sentinel-3A minor issue occurred at Payload Data Ground Segment level, Level-2 STC SRAL user products for the following sensing time will be delayed:

• 2018-09-27T19:15 to 2018-09-27T22:37
  
• 2018-09-28T13:46 to 2018-09-28T23:02
  
• 2018-09-29T15:01 to 2018-09-29T22:35.
  

Recovery of the products is on-going.

As a consequence of a ground segment anomaly, the availability in the Data Hubs of several Sentinel-2 L1C products with sensing time between 27 September 14:18 UTC and 28 September 07:30 UTC is delayed.

The recovery of the missing products is expected to be completed by Monday 1 October.

We apologise for any inconvenience this may cause.

Collaborative users are informed that on the 1st of October 2018 it will be initiated the publication of Sentinel-3A OLCI NRT and NTC products on the Collaborative Hub Access Node 1 for a testing period of 1 week.
During this period, publication and download performances will be monitored.
Following a positive feedback the publication will become nominal and it will be extended to Node 2 and Node 3.

We would like to inform users that the following set of Sentinel-2B products published in Data Hubs have an incorrect file name due to a configuration issue at ground segment level.

Collaborative users are informed that there is the risk of possible service downtimes on ColHub Access Node 3 starting from 11:30 UTC of the 23 September 2018 due to a force majeure event that could affect the data centre hosting the service.
We apologise for the inconvenience that this might cause.

Collaborative users are informed that a maintenance activity on Access Node 1 of the Collaborative Data hub Service will start on Monday 24 September 2018 at 14:00 UTC until Tuesday 25 September 2018 9:30 UTC.
During the maintenance window products publication will be temporarily suspended and a service downtime will occur on Tuesday, the 25th of September 2018, starting from 7:00 UTC until the end of the maintenance window.
Access nodes 2 and 3 will not be affected by the maintenance and will continue their nominal service.
The maintenance aims to upgrade the data hub software to a new version.
We apologize for the inconvenience this may cause to your activity.

The Sentinel-2A Optical Communication Payload (OCP) is unavailable since 20 September 2018 00:36 UTC.

This is currently causing the loss of the Sentinel-2A data downloaded through the European Data Relay System (EDRS).

As a consequence, the Observation Scenario will be temporally reduced. Further news on this anomaly will follow.

Users are informed that a minor update on Sentinel-2 L2A products is going to be implemented to optimise the encoding of the quality bands (SCL, CLD, SNW, PVI, TCI) over 8 bits instead of 16 bits, in line with the Sentinel-2 L1C products.

All L2A products generated as of 19 September 2018 will feature this small change which is compliant to the SNAP software tool.

Infrastructure maintenance activities are scheduled on:

• Tuesday, 18 September 2018
  
• Wednesday, 19 September 2018
  

The maintenance will affect the Data Hub Services according to the following schedule:

Tuesday, 18 September 2018 from 06:00 to 16:30 UTC:

• Copernicus Open Access Hub (also including API Hub, Sentinel-3 Pre-operations Data Hub and GNSS Rinex Pre-operational Hub)
  
• Collaborative Data Hub - Node 1
  

The Collaborative Data Hub - Node 2 and Node 3 will continue to be accessible to their registered users.

Wednesday, 19 September 2018 from 06:00 to 16:30 UTC:

• Copernicus Services Data Hub
  
• Sentinel-3A Pre-operations Data Hub
  

During the maintenance windows service interruptions might occur.

We apologize for any inconvenience caused.

The availability in the Data Hubs of several Sentinel-2 L2A products with sensing date between 27 August and 11 September has been delayed due to a combination of contingencies at ground segment level.

The issue has been solved today, 11 September and the recovery of the missing products is ongoing and is expected to be completed by tomorrow 12 September.

Following the recent upgrades to the Data Hub dissemination points we are pleased to announce that the Long Term Archive (LTA) Access interfaces are ready to be operated, part of the nominal regime to ensure the continued access to all Sentinel Data at all time. As planned, the operations of the data dissemination will soon implement the roll-out of the oldest data from the online access and activation of the interfaces to allow to restore access to historic data from the Long Term Archive (LTA).
The Data Hub dissemination system continues to provide the unified access to all Sentinel Data: the catalogue will continue to publish all data, the discovery and download interfaces (both the graphical user interface and API) provide additional status information to indicate whether the product are online or offline.
Access to the product URL for data that are no longer available online will automatically trigger the retrieval of the data from the LTA, the actual download may be initiated once the data are restored (within minutes to hours). Full details are available in the updated User Guides.

Roll-out of the data will start with the oldest Sentinel-1 RAW data and then will proceed to the other Sentinel product types according to the production volumes and usage patterns.

At least the latest year of Sentinel data will be kept online at all times. The retention period for the various different product types will be tuned according to the usage patterns to ensure efficient access to the most recent and frequently downloaded data, the precise retention period (always greater than one year) is subject to change according to the operational experience.

Due to a major Sentinel-3A Ground Segment anomaly all L1 and L2 NRT OLC, SLSTR and SRAL user products from sensing time 05-09-2018 19:30 to 06-09-2018 06:06 UTC are missing.

Investigation on root cause is on-going

Due to a planned spacecraft manoeuvre on Sentinel-3A on 29 August 2018 all NRT/NTC/STC OLCI and SRAL user products could be degraded from sensing time 07:38 to 08:13 UTC. NRT/NTC SLSTR user products could be degraded from sensing time 07:38 to 08:47 UTC.

As a consequence of a ground segment anomaly, the availability in the Data Hubs of several Sentinel-2 L1C products with sensing date between 29 and 31 August is delayed.
The anomaly has been solved and the recovery of the missing products is ongoing and is expected to be completed by tomorrow, 4 September.
We apologise for any inconvenience this may cause.
