* '''14 Sep 2021''' EUMETSAT announced a technology test for MetOp-A IASI. IASI has been set to the redundant side to do anomaly investigation. 6 days of outage are expected during this test. The outage started 08 September 12z. Expected end time 2021-09-15 10:00:00. The notice states "Please note that data generated after the outage might be degraded." | * '''14 Sep 2021''' EUMETSAT announced a technology test for MetOp-A IASI.

* An additional technology test is scheduled for 2021-09-16 00:00:00 - 2021-10-15 00:00:00. IASI will scan with oversampling. The data quality is expected nominal for the entire duration of the test. However, the scan pattern will be changed (i.e. 30 scan positions will overlap) as the swath will be reduced from 2200 km to ~200 km. 4 hours of outage are foreseen on the first day of the test. | * An additional technology test is scheduled for 2021-09-16 00:00:00 - 2021-10-15 00:00:00.

*'''20 Sep 2021''' The MetOp-A IASI data returned in the 2021-09-15 06z dataset according to coverage plots. At 2021-09-16 12z the number of accepted obs dropped to near zero (presumably with the start of the second technology test). It was decided to turn off MetOp-A IASI data starting with the 12z assimilation on this date (9/20/2021) - this will be the end of our usage of MetOp-A IASI since the data is not expected to be available after the end of the technology test. | |||
