Banding and Striping Images |
07/12/2020 |
07/12/2020 |
The Moon appeared in the G17 ICT spacelook positions at ~03:15z and ~03:20z. These intrusions caused the strong bandings at the B09 and B13 images between 03:15-03:20z and at the B10 and B15 images between 03:20z - 03:25z. One strong banding can also be observed at the B04 FD swath and the MESO image at ~03:15z. The strong striping at the B13 images since 03:20z was caused by the latched spacelook and was resolved by the manual reset of the spacelook at ~04:14z. Details on these anomalies are available in the report by Yu et al. in the CWG weekly meeting on 07/15/2020. |

The G17 B11 images experienced an intermittent striping between ~12:51 UTC on 08/06/2020 and ~21:02 UTC on 08/18/2020 and a strong striping between ~21:02 UTC and ~23:55 UTC on 08/18/2020. The intermittent striping was caused by the unstable detector at the detector row #213 and it was resolved by a BDS update at ~21:02 UTC on 08/18/2020. The strong striping caused an inadvertent BDS update at Row#300 at ~21:02z; and mitigated with a manual spacelook reset at ~23:55z on 08/18/2020 to trigger the band-aid remedy; and recovered with the reverted BDS update at ~18:28 UTC on 08/21/2020. Details in the reports at the CWG 08/19/2020 meeting. |

Calibration Anomaly at 09:00-10:00Z |
02/27/2021 |
03/03/2021 |
Abnormal calibration variation was observed at some G17 IR channels at ~9-10Z from 02/27/2021 to 03/03/2021. The anomaly was associated with the small bump of G17 focal plane module (FPM) temperature during this time period with the maximum magnitude occurred on Mar. 1 |

G17 IR Calibration Anomaly |
08/06/2021 |
08/06/2021 |
G17 ABI experienced a series of anomalies in the images collected at ~09:00 - 09:15Z and ~12Z on 08/06/2021. The root cause of these one-day event anomalies was a large slip of the beginning time of the M3 timelines that day. At ~9UTC it caused the gainset switch occurring within the timeline. At ~12UTC incomplete timeline data were collected. Details are available in the slides presented in the CWG meeting on 08/11/2021 and 08/18/2021. |

01/04/2022 |
01/20/2022 |
Intermittent thin striping was seen in some products of B09 beginning on 1/4/22 at 1:04Z. This was caused by unstable and noisy detector performance from row #296. The detector on this row was switched with a BDS map update on 1/20/22 at 17:38Z which resolved the striping. See details in the CWG presentation on 01/12/2022. |

04/10/2022 |
04/18/2022 |

B12 BDS update |
05/03/2022 |
05/11/2022 |
The detector on B12 row 12 began to show anomalous performance on 05/03/2022 at 04:12Z. The anomalous detector performance can be seen in the L0 data but the row is close enough to the edge of the swath that it is filtered out in the swatch stitching step. The detector on this row was switched with a BDS map update on 05/11/22 at 14:37Z which resolved the anomalous behavior. See details in the CWG presentation on 05/13/2022. |
