* 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 outage for the first test began 2021-09-08 12z. The MetOp-A IASI data returned in the 2021-09-15 06z dataset with a partial swath, 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). The ana.log files had messages about "READ_IASI WARNING uncertainty in lza". 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. | *'''20 Sep 2021''' The MetOp-A IASI outage for the first test began 2021-09-08 12z.

*'''19 Oct 2021''' The MetOp-A IASI instrument was switched off on October 15. Note that all other Metop-A instruments and products will be shut off by November 15, and the satellite will be de-orbited by December 1. In future tags we will be marking the end date for MetOp-A IASI in the 'active_channels.tbl' and the 'available_channels.tbl' as 9/08/21 06z prior to the first outage. By turning off the data in the 'available_channels.tbl' we will avoid the "READ_IASI WARNING uncertainty in lza" error messages that would appear even when the data is read in as passive. | |||
