  3. Overview A few slides from Roger Dahlman Program Manager BER

  4. Carbon Cycle Perspective “Need to understand and predict carbon cycle to address climate response” • Know net CO2 exchange between atmosphere and biosphere • Provide quantitative estimates of terrestrial carbon sinks and sources • Improve models for predicting future atmospheric CO2 • Conduct basic research to understand terrestrial carbon processes

  5. measurements experiments models Terrestrial Carbon Processes Roadmap Goal Forecast terrestrial carbon cycle and its coupling w/global climate Fluxes | Sources | Sinks System Ecosystem | Region | Globe Quantitative and predictive understanding of terrestrial C cycle and its feedbacks Objective TCP Strategy 7.1 What are the spatial and temporal patterns of N. America C sources and sinks? What processes control N. American C sources and sinks? 7.4 How do global terrestrial C sources and sinks change across time scales? 7.5 How will terrestrial C sources and sinks change in the future? 7.5 What will be future [CO2]? R&D Needs CCSP Questions

  6. Terrestrial Carbon Process Goal Provide scientific knowledge of terrestrial components of global carbon cycle -- for • Accurate predictions of atmospheric CO2 change • Evaluating terrestrial sources and sinks Major Programs: AmeriFLux and Free-Air CO2 Enrichment Experiments (FACE)

  7. CO2 fluxes for North America:Combining data from AmeriFlux, tall towers, aircraft and satellites CMDL (Argyle, ME) tall tower

  8. Plant Inputs Root turnover and its affect on soil organic matter response to elevated CO2Jastrow and Matamala Climate Atm CO2 Plant inputs: quality and quantity Carbon Storage Long-term stabilization

  9. Program management Approach • Support high quality science • Provide leadership • Assure program balance • Attention to continuity

  10. General Recommendations • Organization-establish science steering committees • Phase out some of the observational sites that measure CO2 fluxes and establish new high priority sites through peer review process • Upgrade and maintain effective databases for collection observational data, re-analysis some of older data in form useful to the modeling and wider community. • Integrate national observations with the international efforts

  11. Soil Carbon • Need a focus on soil carbon turnover research • Build a national soil carbon model that simulates and predicts fate of below ground carbon over regional and national space scales

  12. Establish a Multi-Scale Modeling Capability • Form a modeling team to develop a National Terrestrial Carbon Model. DOE should take leadership of this effort. • This activity would integrate the observational programs with a national coupled carbon climate modeling activity

  13. Quality of DOE supported research in this area is excellent!Note: More detailed recommendations in the report
