  2. European Research Infrastructure for Earth Observation using passenger aircraft www.iagos.org www.iagos.org IAGOS combines the advantages of MOZAIC and CARIBIC: IAGOS-CORE: Key species (O3, CO , H2O) on several aircraft, every day with quasi-global coverage, 500 flights/ac/yr IAGOS-CARIBIC: Many species for a deeper understanding, on one aircraft, ca. 50 flights/yr, CO, CFCs, SO2, VOCs, aerosols

  3. IAGOS-CORE www.iagos.org www.iagos.org  Permanent installation of instruments in the avionics bay of Airbus A330/A340  Continuous operation with 500 flights per aircraft per year  Regular global-scale in-situ monitoring of atmospheric composition (ozone, water vapour, reactive gases, clouds, greenhouse gases and aerosols)
