Presentation of IAGOS
• IAGOS-ERI is one of the new European Research Infrastructures on the ESFRI 2006, french and german Roadmaps
• IAGOS-ERI is in Preparatory Phase (EU FP7)• In-situ observations of atmospheric reactive and greenhouse gases• Fleet of initially 10-20 longrange in-service aircraft of internationally
operating airlines• Based on MOZAIC program (1994-2010)• Data along flight tracks:
– In-situ concentrations in raw, averaged, and profile data formats– tropopause height, air mass backward trajectories calculted with a
Lagrangian model using ECMWF meteorological analyses

Overview of IAGOS metadata• Time, geographic location, altitude• Name of parameter measured (O3, CO, H2O, NO, NOx, NOy )• Metrology
– Description of the measurement technique– Calibration / correction (history)– Software for QA/QC– Description of flags– Statistics for periods of service
• Coordinates of :– the PIs per parameter– the coordinator– the database computer scientist– the webmaster
• Data protocol• References to relevant publications

Semantic & schemas
• GCMD (Global Change Master Directory) science keywords used for registered terms
• Example for CO :– Domain : earth science– Category : atmosphere– Name : carbon monoxide
• Metadata present in IAGOS database• No output format• FGDC (Federal Geographic Data Committee ) XML schemas used
in the past
Metadata Worksop 7-8 September 2010 in Nijmegen 7
Needs & perspectives
• Need of competence• Utilisation of INSPIRE ?• WMO Information System used for operational transmission• First application : data portal for IAGOS & ICOS
