Service has resumed.

End of distribution of global SNPP CrIS data. This is due to issues with the SNPP CrIS instrument which limit the usefulness of the data for the user community.

The maintenance has been postponed to 28/08/2024. Start and end dates have been updated.

The maintenance has been postponed to 27/08/2024. Start and end dates have been updated.

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.

NOAA has planned a quarterly Cruciform Scan calibration for the GOES-16 space weather EXIS instrument. A EXIS and SUVI product outage can be expected in the given timeframe.

Planned maintenance activity on Data Store and Data Tailor. Users will experience delays in the updates to the Data Store catalogue.

Due to a ground segment maintenance, there is a risk of interruption for the ATMS, CrIS, OMPS-NP, OMPS-TC products from NOAA-20, NOAA-21 and S-NPP, VIIRS-AOD from NOAA-20 and NOAA-21, the GLM products from GOES-East and GOES-West and the data from Himawari-9.

Extended until 31/08/2024.

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.

From 19/03/2024, the daily Meteosat-9 Upper HRV Window shift time will change from 14:00 UTC to 15:00 UTC to better optimise the illumination for the Spring/Summer season. The 15:00 UTC shift time will remain in place until 20 September 2024 included.

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.
