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.

Satellites: Metop-A
Subsystem: GOME-2
Subject: general-announcement
Impact: risk-of-degradation
Detail: The Metop-A satellite with GOME-2 on-board is currently in drifting orbit. As a consequence there are periods during which the GOME-2 instrument is not able to carry out its daily solar calibration measurement. The fourth such period will be from 29 July 2020 until the end of mission of Metop-A. During this period, the solar mean reference spectrum provided in the Metop-A GOME-2 level-1B product will be automatically replaced by a modelled solar spectrum using information on solar activity from Metop-B. Therefore, it is expected that the quality of both level-1B and level-2 products might undergo slight changes during this period, and there will be an associated risk of degraded product quality for Metop-A GOME-2 products.
