  1. Flask network (A 2.3)Multiple species measurement What is expected from A 2.3 for reaching the CarboEurope IP ultimate goals? How far are we? What needs to be done? Activity 2.3 Team CarboEurope-IP Meeting, Posen, Poland, 7-12 Oktober, 2007

  2. 2.3.2.2To develop innovative methodologies using Carbon Cycle related tracers and isotopes to attribute the CO2 concentration in the European air shed to each of the constituent parts of the fluxes: fossil, oceanic, and terrestrial (MO8). Means to achieve objective (Activities 2.2; 2.3; 2.5; 2.6): Multiple species in situ measurements on tall towers Flask air sampling for multiple species analysis at ground stations and aircrafts Quality control program (intercomparisons; calibrations) to integrate atmospheric multiple species measurements from different laboratories Radiocarbon and CO measurements to separate the fossil fuel component General Objectives

  3. O2.3.1: To operate a unified co-operative European network of weekly flask sampling sites distributed among five laboratories. O2.3.2: To use flask multiple-species information to apportion the European carbon balance into components: fossil, air-sea exchange and terrestrial. O2.3.3: To develop new innovative and improvement of already existing analytical methods for measurements such as Ar/N2 (an ideal transport tracer over land); NMHC (a pollution tracer) and 13C in CH4 (tracer of methane sources). Objectives (5 yr plan)

  6. How far are we?

  7. Comparison for CO2 (flask, online) at JFJ

  8. Comparison of CO2 flask records

  9. Bern scale Jena scale Groningen scale Comparison of O2 flask records

  11. In our view those changes can neither be explained by increased fossil fuel emissions nor by a changing biospheric activity. We favour a strong influence from the Atlantic ocean, most probably pentadal or decadal variations of circulation combined with heat storage variations. Valentino et al., in press

  21. Conclusions and the future…: • Network is running but sometimes with rather poor data coverage due to ? ? ? • Flask air measurements help to verify the calibration of continuously recorded values. • In principle multi-species measurements on the same air sample allows us to disentangle processes and quantify their contributions, but the data resolution is critical in this regard. • Data resolution is also a critical issue for trend and amplitude determinations as shown on Sunday during the trend meeting. • I urge people to look not only at their own data, but to use others data and work with them to reach a synthesis until next year. • Thank you for your attention
