Dear all,

due to problems in the data downlink for Metop earlier today, no level0 data was processed between 11:30 and 12:21 UTC today, 13 May 2012.

After level0 data became available again, the operational GRAS processing went through a (expected, given the circumstances) reset of the Precise Orbit Determination and thus produces degraded level 1 data which has been flagged accordingly. Data quality is nominal again since ~ 16:21 UTC. Note that level 2 products from the ROM SAF were also affected by the data outage and subsequent quality degradation.

We apologize for the problems!

Christian Marquardt.
