| Start date | End date (short events) | Event type | Affected data | Description |
|---|---|---|---|---|
| 01/01/2018 | 15/01/2018 | Technical problem | Ocean5 in-situ data | Problem with ocean5 data. The date stamp is wrongly set to 2008 instead of 2018. The problem is being solved. |
| 10/01/2018 | Blacklist | AIREP temperature data | Blacklist of AIREP temperature data. Similar data are provided by experimental AMDAR data. AIREP temperatures are not bias corrected which would create inconsistencies | |
| 12/01/2018 | Blacklist | GEOS-13 AMVs | Blacklist of GOES-13 AMVs | |
| 15/01/2018 | Blacklist update | In-situ data | conventional monthly blacklist update | |

Some processing systems (AAPP and EUMETSAT processing) are less tolerant and had to be updated. This channel is not used at ECMWF |
| 21/06/2018 | Quality issue | AQUA AMSUA Ch14 | :Sudden deterioration of AQUA AMSUA Ch14 and to less extent Ch13. Both systematic and random errors are affected.

| 19/10/2018 | Technical problem | NOAA2-/CrIS | Strangely NOAA-20 CrIS appears to be added to the blacklist (only for LWDA cycles). No blacklist change was implemented. This problem is being investigated. The problem has been solved and it was traced to interference with the FSOI system | |
| 21/10/2018 | Quality issue | NOAA-18 MHS | Anomaly affecting NOAA-18 MHS leading the corrupted observations (missing). The instrument will be blacklisted on 23/10/2018 awaiting further details to assess the situation when the data are back. Data blacklisted on 23/10/2018 | |
