M01 AVHR AMV BFR L2D products are at risk of interruption until further notice.

The Metop ASCAT Soil Moisture products currently generated at the EUMETSAT Central Facility, and distributed on EUMETCast, will be replaced by new, upgraded soil moisture products generated by the H SAF. The current products are planned to be discontinued in Q1 2025 (exact timeline to be announced). For full details, see the link provided below.

Sentinel-3 Altimetry L2P products to be discontinued from 1 January 2025. Users of the Sentinel-3 L2P products are advised to use L2 products from EUMETSAT or L3 products from CMEMS. For full details, see the link provided below.

Routine in-plane manoeuvre. Reduced data quality should be expected for data sensed during this period. The exact burn time will be announced closer to the day of the manoeuvre.

Significant upgrade to the Sentinel-3 Marine SRAL/MWR level 1 and level 2 products, with the release of Baseline Collection 006. Key enhancements include: For L2: Introduction of GDR-G standards, aligning with Sentinel-6 and Jason-3, and the delivery of improved 20Hz data. For L1: Application of Range Walk corrections across all timeliness levels, resulting in enhanced data quality. For full details, see the link provided below.

Date changed to 3 December 2024.

Fairbanks Full Mission Support pass. Risk of interruption to Metop-C data production during the maintenance window.

GOME2 monthly measurements of GOME-2 polarisation (PMD) data in raw readout mode (PMDRAW). The AC SAF Near Real Time Total Column products (Total Column Ozone, the Total Column NO2, and the Tropospheric NO2) will be unavailable.

Planned maintenance activity on Data Store and Data Tailor. Services may become temporarily unavailable during the maintenance period.

East-West Station Keeping Manoeuvre. Users may experience degraded image quality and degraded meteorological product quality up to a few hours after the manoeuvre.

Due to operating system updates.

SEM TED in flight calibration.

A GOES-18 ABI solar calibration scan is planned on 25 November 2024. Between 14:50 and 14:55 UTC GOES-18 ABI will operate in Continuous Full Disk Mode (mode 4) instead of 10-minute Flex Mode (mode 6). Filenames will change to reflect the mode 4 operations, e.g.: OR_ABI-L1b-RadF-M4C01_G18_s20243301450[SSS]_e2024330455[SSS]_c20 2433014[mmssSSS]-136002_0.nc. ABI 10-minute Flex Mode (Mode 6) will resume at 15:00 UTC.

A GOES-16 ABI solar calibration scan is planned on 25 November 2024. Between 10:40 and 10:45 UTC GOES-16 ABI will operate in Continuous Full Disk Mode (mode 4) instead of 10-minute Flex Mode (mode 6). Filenames will change to reflect the mode 4 operations, e.g.: OR_ABI-L1b-RadF-M4C01_G16_s20243301040[SSS]_e20243301045[SSS]_c202433010[mmssSSS]-118900_0.nc. ABI 10-minute Flex Mode (Mode 6) will resume at 10:50 UTC

The FCI maintenance has been extended. The FCI L1c dissemination will be re-activated at the latest on 26/11/2024 13:00 UTC.

MHS FDM switch OFF long period test: short data outage at beginning of test. No data degradation expected during the test.

SARR Transmitter switch-off on 2024/03/20 between 08:37 and 08:52 UTC. The reason is to avoid interferences with other LEOSAR transmitters. The switch-on is expected in 2025 but the date is not yet defined.

During future OLCI Lunar Calibrations for both Sentinel-3A and Sentinel-3B starting on 26/01/2024, a new SRAL calibration sequence will be executed. This will involve a long-duration (~10 mins) CAL1 SAR observation, followed by a CAL2 observation and another long-duration CAL1 SAR observation. This will be executed during the SRAL outage periods associated with the Lunar Calibration manoeuvres, so no additional outage will be introduced.

Starting 14/02/2023 20:35:57 S3A will start performing SRAL external calibrations over a transponder in Leonessa, Italy. To conduct this transponder pass, the on-board Digital Elevation Model (DEM) altitude value must be temporarily updated in RAM, and is reverted immediately after the pass. A short outage immediately before and after the pass will be introduced, and data should be considered degraded as per non-nominal acquisition mode, for a total duration of approx.28 seconds over the transponder location (42.61607° N, 13.03780° E) for all relative orbits number (RON) 270 from cycle 95 (inclusive) onwards

Starting 02/02/2023 10:28:30 S3B will start performing SRAL external calibrations over a corner reflector site in Spain. To conduct this pass, the on-board Digital Elevation Model (DEM) altitude value must be temporarily updated in RAM, and is reverted immediately after the pass. A short outage immediately before and after the pass will be introduced, and data should be considered degraded as per non-nominal acquisition mode, for a total duration of approx.26 seconds over the transponder location (42.052°N, 0.7300° E) for all relative orbits number (RON) 335 - from cycle 75 (inclusive) onwards

Starting 31/01/2023 09:39:49 S3B will start performing SRAL external calibrations over a transponder site in Leonessa. To conduct this transponder pass, the on-board Digital Elevation Model (DEM) altitude value must be temporarily updated in RAM, and is reverted immediately after the pass. A short outage immediately before and after the pass will be introduced, and data should be considered degraded as per non-nominal acquisition mode, for a total duration of approx.27 seconds over the transponder location (42.61607° N, 13.03780° E) for all relative orbits number (RON) 306 - from cycle 75 (inclusive) onwards.
