14/01/201428/01/2014BlacklistMET10 ASR and AMVs

Blacklist of MET10 ASR and AMVs due to the ongoing decontamination of MET10. The blacklist is a preventive one due to the possibility of the decontamination impact on the biases.

OutageFY-3B/MWTSWe stopped receiving FY-3B/MWTS and the cause is likely to be a fault in the instrument antenna

31/01/20143/02/2014OutageOCEANSAT-2/OSCATOutage of OCEANSAT-2/OSCAT due to a switch-off of the SCAT instrument onboard Oceansat-2. Data blacklisted from 03/02/2014 to allow a post checking of the data when back.

OutageMETOP-A/IASIMETOP-A/IASI went in Heater/Refuse Mode. This event occurred just prior to a planned activity (from 19/02/2014 to 23/02/2014) to perform a Parameter update for Compensation device test. An email was sent to EUMETSAT about this operation and from what we understood that a slight impact on the IASI L1 data quality is possible. The data will not be disseminated during the periods of test. Update (22/02/2014): METOP-A/IASI data are back and the quality is unaffected.
21/02/2014
OutageOCEANSAT-2/OSCATOutage to OSCAT winds. According to EUMETSAT the data quality is severely degraded. The backscatter ratios are very low and winds cannot be retrieved correctly. Update (25/02/2014): An electronics problem onboard the Oceansat-2 satellite has been identified and requires a satellite system reconfiguration. The dissemination of OSCAT data will be interrupted for a further week at least. Update (27/02/2014): A preventive blacklist implemented in case the data start to flow again.

Quality changeS-NPP/CrISUpdate of CrIS calibration and this caused a significant change of bias associated with Long Wave channels

02/02/2014
Quality issuesAQUA/AIRSignificant drop of AQUA/AIRS data counts (see timeseries for Ch 75). he alarm system triggered several warnings recently. The MetOffice and Meteo-France monitoring systems are showing similar drop. We think that this is due to bad quality data (identified by a flag within the data) are rejected during the extraction.
02/03/201428/04/2014Reduced availabilityGround-Based GPSSevere drop of Ground-Based GPS data (see timeseries). This drop appeared to be caused by a change by the UK MetOffice of the GTS routing headers.
10/03/201418/03/2014OutageMETOP-B/IASIMETOP-B/IASI unavailable due to an ongoing decontamination operation. The data are back and it seems that the noise is noticeably reduced for a significant number of channels.
12/03/2014
BlacklistMETOP-A/ASCATMETOP-A/ASCAT blacklisted due to an update of the calibration. The data need to be checked. So far the quality of the data is similar to what we had.
20/03/2014
BlacklistMETOP-B/ASCATBlacklist of METOP-B/ASCAT (and maintain the METOP-A/ASCAT blacklist) to allow the use of the correct bias correction file. It was discovered that we are using an old file (used with the previous cycle). As OSCAT is currently unavailable, the system is not using any scatterometer data.
22/03/201429/03/2014OutageAQUA/AIRSThe AIRS instrument is currently experiencing a hardware fault (affecting the cryocoolers used to cool the infrared detectors). We had two cycles of severely degraded data (see timeseries) before NASA's decision to stop the data dissemination. We hope that a corrective action will be implemented
26/03/201421/05/2014OutageMETOP-A/MHSMETOP-A/MHS is experiencing a hardware anomaly. Update (21/03/2014): EUMETSAT successfully restored MHS and the data started to flow again. The data are not being extracted till a blacklist is in place (expected to be done on Tuesday 27 of May)

06/05/201414/05/2014Blacklist GOES-13 and GOES-15 AMVsBlacklist of GOES-13 and GOES-15 AMVs to allow a proper evaluation of the new hourly AMV product. We are having significantly much more data. The quality of low level winds improved significantly (see GOES-13 IR AMVs statistics)

Update: After invetigations, NOAA decided to decommission NOAA-16 after 13 years of service. Before this major anomaly ECMWF was still using data from NOAA-16/AMSUA and NOAA-16/AVHRR AMVs.

15/8/201412/9/2014Quality issuesAIREPAIREP winds were affected by a sudden and severe increase of departures over the North Atlantic (see AIREP wind speed statistics). As a result  AIREP winds were blacklisted on the 19th of August. The problem was caused by an unannounced format change that affected most of AIREP data. A change is needed to adapt the decoding to the new format.

Data increase
Significant increase in the number of in-situ data (see timeseries for SYNOP Ps). The increase was caused by a revision by the MetOffice of the GTS  data routing.
21/10/201424/10/2014OutageData routed from NESDISA network outage at the level of NESDIS caused a severe outage of many satellite data: AIRS, AQUA/AMSUA, GOES-15 and GOES-13 AMVs and CSR, AQUA and TERRA AMVs and COSMIC GPSRO. Other centres were affected too. Most the data came back on the 24th of October except GOES-15, AQUA and TERRA AMVs due the the fact that the ftp site hosting them was not re-established. Production switched to the use of GTS to retrieve these data

This was done at the level of the data producer and led to a significant increase of used data. The departures increased significantly for many channels. The problem is now solved after interaction with the data provider.
