Dear ROM SAF GTS user



Issued 2012-11-27 12:18 UTC



Due to a hardware failure at the EUMETSAT operational ground segment there was a short outage of upstream GRAS level 1b data. Products with observation times between 09:06 and 09:18 might have been disseminated twice both by EUMETSAT and by the ROM SAF processing chains. Data is currently flagged non-nominal but is expected to return to nominal status around 13:15 UTC.



Please see detailed message from EUMETSAT below.



Kind regards

The ROM SAF Team

Subject:Data outage for GRAS on both Metop-A and Metop-B today, 27 Nov 2012

From: Christian Marquardt

Dear all,



due to a hardware problem on our operational ground segment, the operational processing chains for both Metop satellites were interrupted a short while ago. Processing is now back to normal, but the interruption caused a reset in the operational POD systems for both GRAS instruments. The characteristics of the outage are slightly different for the two satellites:



Metop-A:

--------

The reset occurred for a sensing time of 09:06 UTC, and data will be flagged as being degraded up until ca. 13:15 UTC. Data for sensing times between 09:06 and 09:18 might have been sent twice, with the later products being the degraded ones.



Metop-B:

--------

There was data gap between 08:15 and 08:45 UTC. Data between 08:45 and ca. 13:00 UTC will be flagged as degraded.



We apologize for inconvenience.



With kind regards,



 Christian.
