* O-F standard deviations were seen to rise, and an RFC memo circa 3 Jul 2013 stated that NCEP had turned the instrument off. As of the 12z run on 5 Jul, the observations were disabled in forward processing & FPIT. The spike in the radiance monitoring plots is likely due to the software being confused regarding used/rejected data when they switch to passive. | * O-F standard deviations were seen to rise, and an RFC memo circa 3 Jul 2013 stated that NCEP had turned the instrument off.

*'''22 Aug 2013''' NOAA-15 AMSU-A data counts and coverage decreased (first signs ~16 Aug 18UTC) with loss of data spreading southward from the Arctic. Per email from Nigel Atkinson (UK Met Office) this was due to erratic reporting of the A1-2 antenna position for the warm calibration view. The Warm Target View Position Tolerance for NOAA-15 AMSU-A was [http://www.ssd.noaa.gov/PS/SATS/MESS/MSG2341538.01.txt updated on 21 August 2013 at 1248 UTC], followed by a subsequent recovery of data counts and coverage. | |||
