CPDB, WDQMS and OSCAR CPDB WDQMS pilot OSCAR/ Surface

WDQMS, OSCAR in the context of monitoring WDQMS pilot OSCAR Primary purpose Describe how well WIGOS is providing required observations, and report findings, incidents (Quality monitoring & incident mgt. of global/national assets) Understanding observational data, GAP analysis, support WDQMS, support CPDB, use as national DB (Technical doc/analysis of global/national assets) Users Members, Regional WIGOS centers, users of data Network planners/managers, data users (scientists, eg. climatologists), international organizations Temporal resolution 6-hourly Monthly Displays Received vs expected, Used? , O-B (by observation) Declared status, reporting status, schedules , ..

WDQMS -> OSCAR WDQMS -> OSCAR List of stations unknown in OSCAR Reporting status by station and observation to populate OSCAR Through custom web endpoint in WDQMS Decide which observations to use (for the moment, use surface pressure) Monthly Need to define thresholds Link to WDQMS for getting more detail

OSCAR -> WDQMS List of stations for WDQMS station baseline Daily update Currently through VolA legacy file Use OSCAR API in the future Which stations in OSCAR are the WDQMS baseline? Observation frequency for WDQMS reporting status baseline Currently based on old Volume A Need «int. reporting frequency» field in OSCAR (how many observations are shared?)

Next steps Add «international reporting interval» to OSCAR/Surface Link WDQMS-tool to OSCAR/Surface for baseline Enable «reported status» to OSCAR/Surface station report

Reporting status in OSCAR/Surface

Accumulated questions WDQMS Station baseline (OSCAR filter) Joint understanding of «int. reporting interv.» Reporting status codelist in OSCAR
