From the SSD message: On December 3, 2011 (DOY 337) at 21:25Z, there was an increase in the NOAA-17 HIRS filter motor current and temperature. The motor current increased approximately 20mA to 170mA and later dropped back towards its previous level. There was a few tenths of one degree increase in filterwheel temperature. This anomaly, considered as a sign of aging of the HIRS filter motor, mainly affects the HIRS longwave channels. These channels have escalated but stable noise levels. | From the SSD message: On December 3, 2011 (DOY 337) at 21:25Z, there was an increase in the NOAA-17 HIRS filter motor current and temperature.

*'''5 Jan 2012''' - Though I haven't found anything explicitly mentioning the permanent demise of COSMIC FM2, it does agree with GFS Monitoring that observations ceased at at 12 UTC cycle on 28 Dec 2011. These things sometimes come back to the data stream, but usually quicker it happens quicker than this. FM6 seems to be erratically dropping out, but was actually somewhat healthy in most recent cycles. | |||
