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.

Impact:data-degraded
Detail:Technology test. IASI will scan with oversampling. The data quality is expected nominal for the entire duration of the test. However, the scan pattern will be changed (i.e. 30 scan positions will overlap) as the swath will be reduced from 2200 km to ~200 km. 4 hours of outage are foreseen on the first day of the test. This test can have an impact for users that use processing of IASI data. [Rev. 2]: The radiometric quality of IASI L1 data is nominal. However, non-nominal geo-location and inconsistencies between the global and regional data, affecting both L1 and L2 products, are currently being observed. Investigations are on-going. [Rev. 3]: Since 22/09/2021 11:23 UTC sensing time, the quality of Metop-A global IASI L1 data is nominal again. The quality of regional IASI L1 data is expected to be recovered on 27 September 2021. For the status of global and regional IASI L2 data, please refer to UNS Alert message #7371.
