Detail: There is an issue with the latest EUMETCast software package, affecting Linux operating systems when the Tellicast client software (version 2.14.5) is used in combination with the Safenet drivers. A new alpha version of Tellicast, with a fix of the issue, is available for download. See the URL provided below.

Satellites: Metop-A
Subsystem: GOME-2
Subject: general-announcement
Impact: data-degraded
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 third such period will be from 14 November 2019 to 14 April 2020. 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.

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.

Subject: instrument-special-operation
Impact: risk-of-interruption
Detail: On 30 March 2020, the Sentinel-3B SLSTR Cold Finger temperature will be increased from 77.5K to 79.5K to mitigate aging effect on the instrument and maximise instrument availability. This will result in a small increase in NEdT to TIR channels, as well as small changes to the calculated brightness temperature due to a wavelength shift in the channel spectral response function. Sea surface temperature users should ensure they always apply the SSES to minimise the impact of the change (more information can be found in the SLSTR L2 Product Notices – see URL provided below). Please note the SSES will not be optimal for the first few weeks after the update and will be further refined over time as knowledge of the new configuration is gained. As a result of this instrument special operation, there will be a risk period until 17:00 UTC on 30 March. Should instrument decontamination be needed, there would be a risk of interruption to SLSTR (all channels) lasting until 06 April 2020.

Detail: Update to EARS-IASI L2 processing. The configuration of the processing chain for Metop-A has been updated after the irrecoverable degradation of Metop-A/MHS channel 2. This channel is now discarded from the combined microwave-infrared retrieval to recover the product yield and quality from Metop-A. This is implemented in the latest patch of the IASI L2 version 6.5, also deployed in the global processing. The update also involves small changes to the product format. For sample files of the updated EARS-IASI L2 data, please see the FTP link provided below.
