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:	The altitude information in the altimetry products may be degraded during the manoeuvre. The radiometer data in the radiometer and altimetry products may be degraded for the duration between the attitude mode transitions. This will affect the sea surface height, but not the wind and wave content in the altimetry products.
