  5. Summary

  6. ASAP Monitoring at ECMWF • Data reception • Troubleshooting • Monitoring tools at ECMWF • General performance • Conclusions

  7. Change of sign in the reported longitude

  8. No problem provided the reported position is right The whole report rejected by the 4DVAR QC

  9. Again the sign of the longitude is wrong

  10. T799 ANALYSIS Actual position OXVH2 Reported position OXVH2

  11. Bad data passed through the 4DVAR QC No problem for a report with the right position

  12. ASAP Monitoring at ECMWF • Data reception • Troubleshooting • Monitoring tools at ECMWF • Monthly counts • Daily monitoring • General performance • Conclusions

  13. ASAP Monitoring at ECMWF • Data reception • Troubleshooting • Monitoring tools at ECMWF • Monthly counts • Daily monitoring • Data reception • Data usage • Statistics • General performance • Conclusions

  15. ASAP Monitoring at ECMWF • Data reception • Troubleshooting • Monitoring tools at ECMWF • Monthly counts • Daily monitoring • Data reception • Data usage • Statistics • General performance • Conclusions

  16. Temperature statistics for the used data • OB-FG (bias and std) • OB-AN

  17. Wind statistics for the used data OB-FG (VRMS) OB-AN (VRMS)

  18. Humidity statistics for the used data OB-FG (bias and std) OB-AN

  19. ASAP Monitoring at ECMWF • Data reception • Troubleshooting • Monitoring tools at ECMWF • General performance • Conclusions

  20. Impact of the data in the model analysis

  21. 4DVAR QC applied

  27. Conclusions • The number of ASAP reports received at ECMWF show a positive trend since 2005 • The percentage of launches reaching 100 hPa has dropped to 85-90% in 2006 compared to 90-95% in 2005 • Corrupted call-signs received from time to time • Reports with wrong positions received almost every month in 2006. Not detected in Japanese ASAP • ASAP data monitored at ECMWF using a number of products updated on a daily basis in our web site • ASAP statistics have continued to show a good performance

  28. ….. And that’s it, thank you ……. Questions ?
