| 04/07/2017 | Blacklist update | In-situ | Monthly update of in-situ data blacklist | |
| 14/07/2017 | New data | BUFR SYNOP | Substantial increase of BUFR SYNOP data from Spain. these stations belong to AEMET's second-tier automatic weather stations. They have not been 'verified' or added to OSCAR but work on this will start after the summer break. Some stations have data quality issues | |
| 20/07/2017 | New data monitored | FY-3C/GNOS | Passive monitoring of FY-3C/GNOS | |
| 20/07/2017 | Data resumption | Jason2 | Jason2 wave height is back after a long outage | |
| 31/07/2017 | 03/08/2017 | Outage | AQUA/AIRS | Outage of AQUA/AIRS caused by an update of the processing algorithm |
| 2/08/2017 | Metop-B/IASI | Significant bias change (up to 0.2K) affected Metop-B/IASI due to an update of the on-board processing to improve the non-linearity correction for IASI-B | ||
| 3/08/2017 | New data | Moored buoys | Increased number of moored buoys around Spain. The reason is likely to be the use of approved BUFR template. | |
| 11/09/2017 | Blacklist update | In-situ | Monthly blacklisting update including the use of HRes BUFR TEMP from USA and some HRes BUFR from Turkey | |
| 10/10/2017 | Blacklist update | In-situ | Monthly blacklist update including activation of many BUFR radiosondes from Canada | |
| 10/10/2017 | 25/10/2017 | Quality issues | NOAA-19 MHS | On board anomaly affected NOAA-19 MHS. On 11/10/2017 the instrument has been blacklisted |

| 25/10/2017 | Re-activation | NOAA-18/AMSUA | Activation of NOAA-18/AMSUA Channels 5 and 8 after 18 months of being blacklisted as the noise has been consistently reduced | |
| 21/11/2017 | Technical issue | EARS AMSUA | Problem in the encoding of originating center for AMSUA leading to EARS AMSUA data being used as part of the global stream. | |
| 23/11/2017 | Improved quality | FY-3C/GNOS | Fix by CMA of FY-3C GNOS processing. The fix removed the bias | |
