Degraded GRAS level 1 b data

TYPE: NRT-GTS

Description

Dear GRAS SAF GTS user Issued: 2011-01-14 10:30 Upstream GRAS level 1 b data has been degraded since yesterday. GRAS SAF products has been flagged accordingly. Please see detailed message from EUMETSAT below. Best regards The GRAS SAF Team Forwarded message: Subject: GRAS Degraded Data Quality on 13 and 14/01/2011 From: Christian Marquardt Date: 2011-01-14 09:57 UTC Dear all, unfortunately, I have to report on another anomaly in the operational GRAS processing. Due to some data gaps in the level 0 data stream from all instruments which occurred around 11:00 UTC sensing time yesterday, 13/01/2011, the GRAS Precise Orbit Determination (POD) experienced some hickups and went through a reset. Unfortunately, the POD did not converge towards nominal quality as usual. Hence, all GRAS level 1b data products exhibited increasing (and strong) biases with opposite signs for rising and setting occultations. This morning, we finally re-initialized the the POD successfully; data starting from sensing times 07:32 UTC on 14/01/2011 should be ok again. To our knowledge, all affected level 1b data products were flagged as having degraded bending angle data quality accordingly. We apologize for the inconvenience that this might have caused on your side. With kind regards, Christian. -- Dr. Christian Marquardt, Polar System Product Expert EUMETSAT, Am Kavalleriesand 31, D-64295 Darmstadt, Germany
