Resumed to normal operations.

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.

The new Rainfall Rate Quantitative Precipitation Estimation (RRQPE) product will be available from 12/11/2024.

Upgrade of OSI SAF HY-2 Wind products. For full details, see the link provided below.

Release of a new version of ASCAT level 1 PPF (Product Processing Facility), v11.5. For full details and test data, see the link provided below.

The manoeuvre has been moved to 16/10/2024.

McMurdo Maintenance. The enhanced timeliness achieved for Metop-B data through the Antarctic Data Acquisition (ADA) system may be interrupted. Therefore, only nominal Arctic timeliness may be available during the maintenance period.

Station keeping manoeuvre. The semi-major axis will be increased by 15m, resulting in radial orbit errors in the OGDRs. OGDR products may be degraded 30 minutes before and up to 2 hours after the manoeuvre. This will affect the sea surface height, but not the wind and wave content in the products.

Reduced data quality should be expected for data sensed during this period.

Sun interference may affect the EUMETCast broadcast satellites. Users might experience lower signal margin or outages on EUMETCast. The exact times and durations of the signal degradation or outages depend on the reception location.

Moon eclipse. From 22:50 to 22:58 UTC image data may be unavailable or incomplete.

Moon eclipse. From 22:12 to 22:27 UTC image data may be unavailable or incomplete.

Moon eclipse. From 20:17 to 20:37 UTC image data may be unavailable or incomplete.

Due to planned software maintenance at NOAA side on 02/10/2024 there is a risk that GOES-16 and GOES-18 ABI L2 products are not availble in the given time frame.

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.

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.

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

Sun Co-linearity. Repeat cycles between 10:45 and 11:45 UTC might be affected.

Due to ground segment maintenance at EUMETSAT there is a low risk of data interruption in the given time period.

Sun Co-linearity. Repeat cycles between 11:30 and 12:30 UTC might be affected.

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

There is a risk of degraded image quality every night from 22:30 to 01:30 next day in the given time period.

There is a risk of degraded image quality every night from 23:15 to 02:00 next day in the given time period.

Extended until 30/10/2024

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.

Updated end time.

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.
