Due to Copernicus Sentinel-3A OLCI calibration, OLCI products degradation is expected for sensing time from 30/06/2024T09:04:20 to 30/06/2024T09:05:30 UTC.

The Sentinel-3 Altimeter Processing Baseline (PB) 3.29 was deployed on June 22, 2024, at the ESA S3A Production Services, synchronised to the start of cycle 113 in NTC timeliness. It will be operated at the ESA S3B Production Service starting from July 1, 2024, with the beginning of cycle 94 in NTC timeliness.

The new Processing Baseline 3.29 includes the following main evolutions:

· A “Sea Ice Type” information is available in the Sea Ice Thematic Product, extracted from OSI-SAF 403-d products (https://osi-saf.eumetsat.int/products/osi-403-d/). Sea ice type classifies ice-covered areas into two categories, based on the sea ice age: multiyear ice versus seasonal first-year ice.

· A new surface type variable is available in the Land Ice Thematic Product, extracted from the BedMachine data set. With this information, users will be able to more accurately discriminate ice sheet and ice shelf surfaces in Antarctica and Greenland. The information is also used to determine with better accuracy the adequate set of geophysical corrections applied on the altimeter range. References:

• Greenland: https://nsidc.org/data/idbmg4/versions/5

• Antarctica: https://nsidc.org/data/nsidc-0756/versions/3

· New product variables are available in the Hydrology Thematic Product, providing information related to Open Loop Tracking Command (OLTC) settings. For each 20 Hz records, users will be able to know if the on-board tracking was finely tuned, or not, for monitoring water bodies overflown by the satellite. The location of these hydrological targets can be found on: https://www.altimetry-hydro.eu/.

• The inclusion of additional islands, and the Maracaibo Lake, in the Hydrology Thematic Products. Polygons from the HydroLakes database are defined over the new selected islands (https://www.hydrosheds.org/products/hydrolakes).

PB 3.29 also includes the resolution of minor anomalies, particularly a correction for avoiding MWR missing data near moon calibration.

The On-Demand Production extends the On-Demand Processing service with the generation of standard Sentinel-1 and Sentinel-3 products using the IPF processors.

Users can now choose the baseline and modify selected parameters of the processing chain to obtain alternative versions of the Copernicus products. The processing starts from the Level-0 and the output is made available for download.

More information on the data processing is available in the SentiWiki (copernicus.eu).

Sentinel-1 processing chains: Sentinel-1 Processing (copernicus.eu)

Sentinel-3 processing chains: Sentinel-3 Processing (copernicus.eu)

The service is available both through the API (Documentation - On-Demand Production API (copernicus.eu)) and Data Workspace | Copernicus Data Space Ecosystem

Dear CDSE users,

We would like to inform you about upcoming Security System upgrade window scheduled on June 6th between 20:00 - 23:00 CEST.

The upgrade will take place due to the scheduled optimization and enhancement of our system's security, with the emphasis on:

• Security System upgrade to newer version.

During the upgrade window, there might be temporary service disruptions of specific components, which may result in the difficulties mentioned below:

• Disconnection of active sessions.

We will strive to ensure that the work proceeds as quickly and smoothly as possible. We apologize for any inconvenience and appreciate your patience and understanding.

Best regards,

Copernicus Data Space Ecosystem Support Team

The Copernicus DEM, a digital surface model that captures terrain and infrastructure on Earth, is now accessible via the Copernicus Data Space Ecosystem.

The DEM is an element of the Copernicus Contributing Missions (CCM) activity, which is managed by ESA from its centre for Earth observation (ESRIN) on behalf of the European Commission.

The migration of the DEM forms part of a gradual relocation of CCM data to the Copernicus Data Space Ecosystem that is creating a central point of access to systematic CCM collections and observations from the Copernicus Sentinels.

This set of systematic CCM collections includes optical high resolution and VHR European and Sub-Saharan Africa coverages, urban atlas or digital elevation models at European and global scales, as well as synthetic aperture radar imagery for sea ice monitoring.

Discover more about the Copernicus DEM in this infographic:

You can keep up to date with the availability of the DEM, as well as other systematic CCM collections, via the Copernicus Data Space Ecosystem CCM collections page.

Due to Copernicus Sentinel-3B In-Plane Manoeuvre, SLSTR products degradation is expected for sensing time from 15/05/2024T07:30:27 to 15/05/2024T07:41:00 UTC.

Dear CDSE users,

We would like to inform you that on May 16th from 21:00 to 23:00 CEST we plan to perform an upgrade of the Identity system.
During the works, it will be possible to log in and generate tokens along with downloading products from the CDSE catalogue.
The impact of this upgrade will be an unavailability of registering and making changes in user profile, for example password change. Any changes made to the user profile during the works will be lost and will not be processed afterwards.
Please do not register a new account or make changes to your profile during the time window mentioned above.
We will make every effort to ensure that the works go as quickly and smoothly as possible. We apologize for any inconvenience this may cause, and thank you for your patience and understanding.

Due to Copernicus Sentinel-3A In-Plane Manoeuvre, SLSTR products degradation is expected for sensing time from 08/05/2024T07:50:45 to 08/05/2024T08:00:35 UTC.

We are pleased to announce a new processing baseline ID for Copernicus Sentinel-3 concerning the following products:

OLCI L1 products OL_1_EFR

OLCI L1 products OL_1_ERR

The new Processing Baseline includes:

• A new spectral temporal model has been implemented, further recommendation from the OLCI/SYN Quality Working Group, to correct the OLCI spectral response drift (of up to 3 nm) observed over time.

• To follow the recommendation from GCOS, a new Solar Irradiance Spectrum of TSIS-1 HRSR 2021 has been implemented, instead of Thuillier 2003.

• The change of pressure level for the relative humidity (rh@950hPa in ECMWF files) has been accounted for

• Update of the radiometric and geometric calibration auxiliary files

It shall be noted that the baseline collection has been increased to 04.00.00 and that the reference version of the OLCI L1 IPF has been upgraded from 6.17.0 to 6.19.0.

The new processing baseline will be deployed on 06/05/2024 for Copernicus Sentinel-3A and Sentinel-3B.

This same processing baseline is also being used for the OLCI historical re-processing campaign conducted at EUMETSAT which will be released in the near future.

Network component update

We would like to inform you about an upcoming scheduled maintenance window that will be taking place on 07-05-2024 between 20:00 and 22:00 CEST.
The maintenance will take place due to the scheduled update of network component.

During the maintenance window, there might be temporary service disruptions of specific components, which may result in the difficulties mentioned below:

• The network component update is planned without CDSE platform disruption; however, there is a risk of temporary unavailability.

We will make every effort to ensure that the works go as quickly and smoothly as possible. We apologize for any inconvenience this may cause and thank you for your patience and understanding.
