|---|
| 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 |

| 23/05/2018 | 4/06/2018 | Quality issue | NOAA-19/MHS Ch3 | Onset of problems affecting NOAA-19/MHS Ch3 causing very large O-B errors (see here). The problem is related to the cold counts for MHS channel 3 that are exceeding the limit that has been used since launch. 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. The reason is still unknown but being investigated. A blacklist change is planned for 25/06/2018. Blacklist implemented on 24/06/2018 |
