Presentation Transcript

  1. What has happened? Science: Regional Experiment CarboTatra

  2. What has happened? Administration: Change in team of the CarboEurope office • Annette Freibauer: overview, strategic decisions, workplan, policy relations • Angelika Thuille: day-to-day management • Yvonne Hofmann: secretary, webpage • (Hendrik Tilger: IT support)

  3. What has happened? Conferences • CarboEurope session at EGU • CarboSchool presentation at EGU • 7th CO2 conference Boulder Workshops • CarboSchool workshop • Concerted Action workshop on monitoring strategies • Graz workshops about 1st commitment period and future of Kyoto Protocol • numerous meetings of Components and smaller project groups • CarboEurope-related presentations at scientific and policy meetings

  4. Main results • Ciais-Nature and further insights (cf. 2003 session, bottom-up/top-down) • variability driven by climate – the value of long-term measurements and intensive data/model interactions (cf. 2003 session, publications) • Cescatti-Advection and further insights (cf. Aubinet paper, advection session)

  5. Future: Closing FP5 projects TCOS Siberia Chiotto C-Invent Camels GHG-CA

  6. Closing FP5 projects: Chiotto Project extended to allow several months of data from towers (and modelling) until March 2006 Status of Tall Towers • 3 running OK, 3 with problems, Orleans tower will start in 2006 • the towers in operation meet or are very close to the WMO precision targets Workshop planned for March 2006 Amsterdam

  7. Closing FP5 projects: GHG-Concerted Action Finished with stakeholder workshop in November 2005 Update of European GHG balance • forest sink smaller than estimated (225 TgC/yr) • cropland and grassland C flux unknown • peatlands and estuaries: GHG hotspots • high uncertainty in non-forest ecosystems

  8. Closing FP5 projects: CarboInvent Successful workshops for policy makers • Land-use Related Choices under the Kyoto Protocol • Options for Including LULUCF Activities in a Post-2012 International Climate Agreement

  9. Closing FP5 projects: CAMELS One Prototype CCDAS completed No integration of forest inventory data in biogeochemical models

  10. Future: What is expected in 2006? • Ecosystems: Continuation and optimization of ecosystem CO2 flux network, first synthesis of major ecosystem types • Atmosphere: Multiple gas species assets to attribute the European C balance to controlling processes, high frequency aircraft profiles • Regional experiment: analysis of intensive campaign and preparation of 2007 campaign • Integration: First assessment of upscaling techniques from point flux measurements to Eurogrid • Initiatives for further Nature papers!

  11. European-wide anomalies of climate and NPP during 2003 All data compare 2003 and the average of 1998–2002. a changes in Jul-Sep air temperature b changes in annual precipitation c simulated changes in Jul-Sep NPP d simul. changes in annual mean NPP e satellite observed changes in FAPAR f simulated changes in FAPAR Ciais et al.

  23. The value of ancillary ecosystem data Davi et al. (2005) CASTANEA (biophysical model)

  24. monthly sums of GPP Reco NEE for the 7-year measurement period 7-year regional NEE from tall tower measurements Haszpra et al. (2005) weak net CO2 sink: 107±48 and 69±37 gC m2 year-1

  25. Regional atmospheric sampling roughly captures ecosystem d13C signals Hemming et al. (2005) longitudinal trends in the d13C of ecosystem respired CO2, site averages for July/August

  29. The Future • Will we close the gap? Janssens et al. (2003)

  30. The Future • Will we close the gap? • Will we get a handle on the uncertainty of NEE?

  31. Kutsch et al. (in prep.)

  32. The Future • Will we close the gap? • Will we get a handle on the uncertainty of NEE? • Will we incorporate management in ecosystem models? • Can we reward the maintenance of C-stocks?

  33. Main Events • Kyoto-COP11: 2 side events with CarboEurope • EGU General Assembly 2006, Vienna, Austria, 02–07 April06 • International Conference on Regional Carbon Budget Beijing, 16-18 Aug06 • ESSP Open Science Conference Beijing, 9-12 Nov06 • Next annual meeting date • Start of NitroEurope Feb06 • Pending proposalsSiberia Africa Amazonia

  34. Wattenbach Conclusions Even low uncertainties (measurement errors) lead to considerable site specific uncertainty in NEE predictions (up to 1 t C/ha) Reduction in model uncertainty can only be achieved by more precision and accuracy in measurements Model uncertainty will always be higher than measurement uncertainty as the input uncertainties amplify each other in the propagation process
