Subject: general-announcement
Impact: data-unavailable
Detail: HRPT switching zone drift. Risk of interruption. The Metop-A satellite is currently in drifting orbit. As a consequence the geographical zones, defined to control the switching times of the satellite HRPT system, are drifting westwards at a rate of 0.02 degree per day. Users near the borders of switching zones might experience small changes in their acquisition times of the HRPT signal. On-board timings will be updated approximately every 8 months to compensate for the drift geolocation. A dedicated announcement will be issued in advance of each of these updates.

Detail: Sentinel-3 OLCI Level-1 Full Resolution Near Real Time data will be removed from EUMETCast Satellite on 29 July 2021. Alternative services to access these data are available. For full details, see the URL provided below. [Rev. 2]: URL updated, following the launch of the new EUMETSAT website on 16 November 2020. [Rev. 3]: The removal of Sentinel-3 OLCI Level-1 Full Resolution Near Real Time data from EUMETCast Satellite, initially planned for 29 July 2021, is being deferred to a later date (likely to be during the last quarter of 2021). This is to allow more time for users to transition to alternative access services.
