Automatic satellite data checking
 

 

 

An automatic satellite data checking system has been implemented at METEO-FRANCE. It triggers the production of alarm messages if an anomaly is detected in the quality or the availability of the satellite data assimilated by the model. Selected statistical parameters such like number of observations (assimilated and rejected data), bias and standard deviation of background and analysis departures are checked against an expected range foreach long cut-off assimilation cycle. An appropriate alert message is generated if these statistics are outside the specified ranges.
Auto-alert service is available on the right hand side of each satellite monitoring page for the following satellite data types :
