Following the renewal of the ESA S3 Processing Services, the former Land Processing Centre codes "LN1", "LN2" and "LN3" will no longer be used. Instead two new Centre Codes "PS1" and "PS2" will be used to identify the new Processing Services. Nominally "PS1" corresponds to the service performing the systematic processing of "S3-A" data and "PS2" to the service performing the systematic processing of "S3-B" data.

For example:

  • S3A_SL_2_LST____20220323T235901_20220324T000201_20220324T004828_0179_083_216_0540_PS1_O_NR_004.SEN3.zip
  • S3B_OL_1_EFR____20220321T005607_20220321T005907_20220321T091528_0179_064_031_1620_PS2_O_NT_002.SEN3.zip

instead of:

  • S3A_SL_2_LST____20220323T235901_20220324T000201_20220324T023054_0179_083_216_0540_LN2_O_NR_004.SEN3.zip

Furthermore, the following information will be updated accordingly:

  • processing centre information present in the product manifest

  • Sentinel-3 file naming convention as:

The switch to the new processing services will take place on 5th April 2022.

Due to Copernicus Sentinel-3B Out-of-Plane orbit correction manoeuvre, instruments products degradation is expected for sensing time from 06/04/2022T08:21:27 to 06/04/2022T08:54:46

A maintenance activity on data hub services is scheduled for April 6, 2022 from 07:30 to 16:30 UTC.
During this time, a publishing delay for Sentinel-1A may occasionally occur on the following hubs:

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

A maintenance activity on data hub services is scheduled for April 5, 2022 from 07:30 to 16:30 UTC.
During this time, a publishing delay for Sentinel-3A and B may occasionally occur on the following hubs:

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

Collision avoidance manoeuvres will be executed on Sentinel-1A to reduce the risk of collision with a Zenit-2 rocket fragmentation debris (1992), potentially occurring today 1st April 2022 at 19:29 UTC.

Three Sentinel-1A data download links through the European Data Relay Satellite System (EDRS), taking place between 16:57 UTC and 20:42 UTC on 1st April 2022, will be cancelled due to these orbit manoeuvres.

SAR acquisitions taking place slightly before and during this period may be affected.

A state-of-the art unmanned aircraft has been dispatched to collect precise water surface height measurements and high-resolution imagery of an 18km stretch of river in the south of France. This information will be used to validate data on inland water courses delivered by Europe’s flagship Earth observation programme.

ESA is pleased to announce the availability of Copernicus Sentinel-3 altimetry data set generated by the NEW ESA Sentinel-3 Thematic Instrument Processing Facilities (T-IPFs). Planned to be deployed in spring 2022 by the ESA Payload Data Ground Segment (PDGS), the LAND T-IPFs are dedicated and specialized delay-Doppler and Level-2 processing chains over Sea-Ice (SI), Land Ice (LI) and Hydrological (HY) surfaces.

In January 2022, a first Test Data Test (TDS) was produced for Hydrology and Sea Ice thematic products (details here: https://sentinel.esa.int/web/sentinel/-/s3-stm-thematic-products-1st-dataset ).

Following this first TDS release, ESA is pleased to announce the availability of a new TDS, including Land Ice thematic products. The Land Ice T-IPF includes major processing evolutions, as detailed below. Compared to the current Sentinel-3 STM level-2 products, the format of the new level-2 thematic products has changed. The document describing the new Sentinel-3 STM land level-2 Product Format Specifications (PFS) is available in the ftp folder (see below for access information).

In the newly generated TDS,  the Sea-Ice and Hydrology products have been updated compared to the first TDS, to include some adjustments of the product geographical coverage. These TDS are released to the end users prior to the deployment of the T-IPFs, so they can become familiar with the new product format, and adapt their tools and processes in consequence. For any feedbacks or questions regarding the TDS, please contact: s3mpc-stm-user-request@groupcls.com.

Due to Copernicus Sentinel-3A In-Plane [CAM] Manoeuvres, SLSTR and OLCI products degradation is expected for sensing time from 16-03-2022T23:55:51 to 17-03-2022T01:47:50.

Due to Copernicus Sentinel-3A Lunar Calibration operation, instruments products degradation is expected for sensing time from 18-03-2022T15:38:02 to 18-03-2022T16:28:32.

An evolution of the Sentinel-1 processing baseline will be introduced on 23 March for all newly generated products. This evolution features two main items:

  • A minor evolution of the Sentinel-1 Level-2 OCN product format, in line with the product format version 3.11. The subject product format specifications are available here together with a set of corresponding sample products.

  • Further to our news of 3 September 2021 the correction of Radio Frequency Interference (RFI) will be applied to IW and EW products.

This evolution will be activated with the deployment of the new instrument processor version 3.5.1.

Products generated after the deployment of this version will tag version 3.5.1 of the operational processor in the corresponding product metadata and will be aligned with the new product format specifications 3.11.
