A healthy observing system is vital for NWP. Observations are allowed to be used once their quality and impact are judged satisfactory. However the observing system is continuously evolving and it is important to monitor the quality and availability events. An automatic warning system is operated by ECMWF to flag data events that can potentially impact the quality of the analysis. Once flagged, events are investigated by scientists to evaluate the root cause and the potential impact. Actions are triggered when necessary. This interface provides a high level view of the status of the various of the observing system used at ECMWF. It uses a traffic light system to indicate the absence or presence of warnings. Additional details about each warning is available when selecting the data type in question. The interface is accessing the events automatically from ECMWF's observation events database. The last 24 hours status is shown by default but users can adjust the period if needed.
For each flagged anomaly, the automatic checking system assigns a severity level depending on how far statistics are from the expected values. When an anomaly persists over many data assimilation cycles the severity level is adjusted to highlight persistence.
The severity level categories:
| Symbol | Description |
|---|---|
⛔⛔⛔ | Persistent anomaly in the severe category |
| ⛔ | Severe anomaly |
| ✋✋✋ | Considerable persistent anomaly |
| ✋ | Considerable anomaly |
| Slight anomaly | |
✅ | No anomalies detected |
