Copernicus Sentinel-1A was unavailable between 19:07 UTC on 1st March 2022 and 12:01 UTC on 2nd March 2022, due to a Payload Data Handling and Transmission (PDHT) sub-system software anomaly.
No SAR data were generated during this period, data acquired slightly before this period may have been affected.
We are pleased to announce a new processing baseline [FRP_NTC.004.07.00] for Copernicus Sentinel-3 concerning the following products:
SL_2_FRP in NTC timeliness
Information about the changes and the characterisation of the new version of the FRP NTC products is available in the following product notice:
A new version v1.4 of the Product Data Format Specification is also published.
The new processing baseline was deployed on the 28th of February 2022.
Following the previous news on the Sentinel-1B anomaly that occurred on 23 December 2021, very detailed investigations related to the satellite power system’s affected unit are still on-going. The anomaly is related to a 28V power regulated bus that supplies power to the SAR electronics subsystem. The reactivation of both the main and redundant power regulators of this 28V bus have not been successful so far.
Whereas good progress has been made on the investigation of 18 identified possible failure scenarios linked to the affected power unit, at this stage the root cause of the anomaly has not been clearly identified. Satellite system level analyses are conducted in parallel, with the aim to perform new recovery attempts of the unit.
The satellite remains under control, the thermal control system works properly, regular orbit control manoeuvres are routinely performed.
Sentinel-1 users should assume a long-term unavailability of data provision (several months). It is however too early to consider a permanent unavailability of Sentinel-1B.
We apologize for the inconvenience caused.
Copernicus Sentinel-1A was unavailable on 22 February 2022 between 04:54 UTC and 14:37 UTC, due to a Payload Data Handling and Transmission (PDHT) sub-system anomaly.
No data were generated during this period, data acquired slightly before this period may have been affected.
Due to Copernicus Sentinel-3A In-Plane manoeuvre on 23rd February 2022, SLSTR Level-1 and Level-2 production degradation is expected for sensing time from 23/02/2022T07:33:46 to 23/02/2022T07:43:36.
A maintenance activity on the data hub services is planned on 23 February 2022 from 07:30 to 16:30 UTC.
During this period, publication delay for all Sentinel-1,Sentinel-2 Sentinel-3 Sentinel-5P products, might occasionally occur on the following hubs:
We apologize for any inconvenience this might cause to your activities.
Due to Copernicus Sentinel-3B OLCI Instrument on-board calibration on 27th February 2022, OLCI Level-1 and Level-2 production unavailability is expected for sensing time from 27/02/2022T09:06:03 to 27/02/2022T09:07:13.
An update of the Copernicus Sentinel-5 Precursor (S5p) operational ground-processing system is planned during 9/03/2022. This includes an optimisation in the processing of Sulfur Dioxide (SO2) and Formaldehyde (HCHO) products, and an update/addition of related metadata:
The global attribute "Status_reference_spectrum" has been updated. Previous version could take values "solar" and "earth" while in the new one (version 2.3) it can take "solar" , "nominal_earth" and "fallback_earth"
The following additional metadata attributes are included in the background correction part of the products (/PRODUCT/SUPPORT_DATA/INPUT_DATA/BACKGROUND_CORRECTION/):
fallback_reference_date
fallback_reference_date_difference
fallback_aux_bg_source_filename
fallback_aux_bg_source_processingMode
fallback_l2_source_filename
fallback_l2_source_processingMode
fallback_l2_source_orbit
fallback_l2_source_sensing_time_start
fallback_l2_source_sensing_time_end
Sample data are available here.
Detailed information will be provided within the Product Readme File.
Please note that NRT products for data acquired during the downtime period will be not generated. After the successful deployment of the new system, version numbers of the first orbit generated with the new version of the S5P operational processors both, in NRT and OFFL, will be provided.
Due to the Sentinel-3A OLCI instrument Calibration planned on 17th of February 2022, a degradation of Copernicus Sentinel-3A OLCI products is expected for sensing time from 17-02-2022T09:04:23 to 17-02-2022T09:05:33.
Due to Copernicus Sentinel-3B Moon calibration operation, data degradation is expected, as reported hereafter:
