1. WIGOS monitoring a pilot project WMO; Name of Department (ND)

2. Context Roadmap and action items from WIGOS QM WS 5.GOS QM Pilots (SG-QM)  Pilot (2015 - ECMWF, NCEP, others?) [R.Grumbine, D.Richardson]  Participating NWP centers to agree on:  Information to exchange;  Format for exchange;  Feasiblity and commencement.

3. WIGOS Monitoring  There layers  Level 1 : WIS (connection layer)  Level 2 : WIGOS (message layer)  Level 3 : WIGOS (content layer) We are here

4. WIGOS Monitoring - report 1.Information to exchange  For each received bulletin  6h exchange frequency 2.Format to exchange  CSV  Webservice / FTP 3.Feasibility and commencement .. Station idDateHourLat/longVariableStatusCenter

5. Approach  Develop pilot @WMO.. Visibility  Goal: fix issues dicovered by monitoring  Improve and vombine with already existing monitoring systems (SMM, AGM, SAM)  5

6. Approach  Periodically receive all not yet processed files (from ECMWF, NCEP)  Determine share of missing observations  Store 1 row per center, variable, (type) and 6h period in database  Interactive website shows stats by station/country/region on map and table  Also show historical development  Show «life» status of observing network  Operations could/should evenutlly be taken over by a NWP centre or other interested centre

7. Aproach – difficulties  What is missing is difficult to tell, as there is no clear baseline  VolA/oscar  SMM works only on RBSN bulletins (where # of observations is known)  As more observations are made it is increasingly difficult to identify which are e.g synoptic ones  Operations? (technology is heavy)  What about existing monitoring?

8. Some thoughts  Constitutes some shift.. Observations only «matter» when they make it to a NWP center  No bias towards a particular center as user can select which one..  Acting on the information is most important component (link with FMS?)  How (much?) to link to OSCAR?
