== MetOp-A MHS ch 2 deterioration, summer/fall 2019 == | |||
* Noise levels on MetOp-A MHS channel 2 began to increase early in 2019, exceeding the instrument specification level in April 2019. | |||
* The problem was not noticed until later in the year, until after the accepted observation count dropped dramatically through October and November 2019. The MHS instrument was turned off in the 5_22 FP system at 2019/12/13 00z and from 2019/11/02 in MERRA2. | |||
* The system experiment x0039 was being continued through September 2019 when the problem was discovered, and it was decided to turn off MetOp-A MHS from 2019/09/15 00z. There was an error made when adding this configuration to the DAS tag however, so the initial run of the x0041 Winter 2019 experiment had MetOp-A MHS still being assimilated in late 2009 and had to be rerun. At that time a decision was made to move the turn-off date in the DAS tag to April 15 2019 00z. | |||
