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: | During the indicated period, the GRAS receiver onboard Metop-A will undergo a series of tracking parameter tests aiming at extending the measurements in the ionosphere. During this period, the number of daily occultations from Metop-A as well as the penetration of rising occultations into the mid and lower troposphere might vary more than usual. Periodic outages of 1 orbit will be possible due to patch uplink to the instrument.

Detail: | Release of a new Processing Baseline (PB), v1.40, for Sentinel-3B SLSTR Level 1 products. The only change to the PB is a new SLSTR-B calibration parameters Auxiliary Data File (ADF) for the S7 oblique view in order to raise an invalid radiance flag when the S7 oblique view brightness temperature (BT) is above 305 K. The maximum valid brightness temperature of the S7 channel was increased beyond 305 K for hot-spot applications and this change is now flagging oblique view S7 BTs above 305 K as 'S7 invalid radiances' as the values are beyond the nominal limits of the channel and, therefore, should be used with extreme caution depending on the user application and associated quality requirements.
