  1. Current and future developments around the IAGOS metadata Damien Boulanger & Valérie Thouret Laboratoire d’Aérologie (CNRS) Metadata Worksop 7-8 September 2010 in Nijmegen

  2. 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 Metadata Worksop 7-8 September 2010 in Nijmegen

  3. MOZAIC (1994-2010) • MOZAIC 1994-2010 Measurements of Ozone, Water Vapour, Carbon Monoxide and Nitrogen Oxides by Airbus In-service Aircrafthttp://mozaic.aero.obs-mip.fr/web/ • Tropospheric ozone budget (0-12 km) : • UV filter and GHG at the tropopause • Oxyding capacity of the troposphere • Pollutant in the boundary layer • Support from the European Commission, french and german institutes, Airbus, and airlines (Lufthansa, Air France, Austrian, Sabena, Air Namibia) > 31000 flights since 1994 Data base opened to worlwide scientists > 150 peer-reviewed papers using MOZAIC data 2010: still two A340s from Lufthansa in operation for IAGOS Metadata Worksop 7-8 September 2010 in Nijmegen

  4. H2O, O3, CO, CO2 NOy, NOx, aerosol, cloud particles H2O, O3, CO, NOy Scientific publications H2O, O3 IAGOS MOZAIC 1993 2001 2005 2012 CARIBIC In-service Aircraft for a Global Observing System European Research Infrastructure www.iagos.org Metadata Worksop 7-8 September 2010 in Nijmegen

  5. 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 Metadata Worksop 7-8 September 2010 in Nijmegen

  6. 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 Metadata Worksop 7-8 September 2010 in Nijmegen
