| Detail: | 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. |

| Detail: | 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 |

| Detail: | Following the release on EUMETCast of Level-1B NOAA-procured Spire Radio Occultation data processed by EUMETSAT, and L2 product generated by the ROM SAF, on 20 June 2023 (see URL provided below for reference), NOAA will switch from Spire to another data provider, PlanetiQ, on 18 July 2023, corresponding to the start of their next 6-month delivery order. As we need to adapt our processor to the new PlanetiQ data, a gap in the provision of NOAA commercial RO data is to be expected starting 18 July. An announcement will be issued as soon as we have a date for the start of dissemination of the new PlanetiQ data. |
