  1. Translation to the New TCO Panel Beverly Law Prof. Global Change Forest Science Science Chair, AmeriFlux Network Oregon State University

  2. U.S. Department of Energy Protocols for Data Collection and Submission Office of Science • Need: • Uniform methods, standards for high quality observations • Uniform database for global assessments • Important standards/definitions: • Carbon stocks in vegetation and soil, productivity, ecosystem & component fluxes • Vegetation types • Land use • Reference for other documents (ECV, GEO Carbon Report)

  3. Protocols • Carbon stocks in forests, agricultural crops, shrublands • Live and dead wood in forests (revise – explicit estimates of biomass mortality by species + metadata) • Understory vegetation in forests (specify biomass mortality) • Foliar, litter carbon • Soil carbon • NPP • LAI • Ecosystem CO2 & water fluxes • Component fluxes (e.g. soil resp.) • Foliar, litter, soil C & N content • Relevant to land degradation

  4. FLUXNET: A Global Network of Observation Sites500+ Sites, 10 Regional Networks, 45 Countries Quantify and understand causes of variation in terrestrial exchange of carbon, water and energy with atmosphere www.fluxdata.org

  5. FLUXNET: Global Terrestrial Flux Observations • Carbon/water/energy fluxes • Meteorology, soil and plant variables • Multiple biomes and disturbances in a broad range of climate • Standardized database, shared protocols (Law et al. FAO 2008)

  6. Transitional activities • Contribute to: • Clarification of roles of programs to reduce redundancy • Ensuring coherence of products, terminology, methods, and standards • Process for feedback among programs and with research developments • Incorporate land degradation – relevant to carbon • GEO Carbon Report

  7. Proposed future activities • Interactions among programs • Update FAO field and data submission protocols • Ecosystem variables relevant to terrestrial carbon, including land degradation • Fill existing gaps (e.g. methods for tropical forests) • Broad agreement • Recommendations for operational systems (depending on resources) • Optimize location and number of in situ observations • Land degradation, deforestation, desertification, drought effects

  8. Moderate Resolution Remote SensingDeforestation (Huang et al. 2009) GOFC-GOLD Recommendations

  9. Moderate Resolution Remote Sensing Desertification

  10. GEO Integrated Global Carbon Observations • Provide long-term observations required to improve the understanding of the current state and future behavior of the global carbon cycle • Monitor and assess the effectiveness of carbon sequestration and/or emission reduction activities on global atmospheric CO2 levels

  11. Integrated Global Carbon Observations: Essential Elements (GEO Carbon Report) • Terrestrial ecosystem flux observations (CO2, water vapor, heat fluxes) • Ocean and atmosphere in situ measurements • Inventories • Global satellite data • Models to integrate these observations for spatial maps of carbon stocks and fluxes • Operational system for policy relevant carbon information

  12. Issues • Continuity of and gaps in existing carbon observation systems • Landsat Data Continuity Mission starts 2012 (2 yr gap 2010-2012) • Terrestrial flux regional networks • Spatial & temporal continuity of soil carbon monitoring, methods used • Carbon variables missing in current inventories • Communicate operational observation needs • Incorporating new methods of measurement/analysis/integration LCDM sensor

  13. LandTrendr: Landsat-based Detection of Trends in Disturbance and Recovery Steps in the LandTrendr process Evaluate veracity of selected events Prepare stack of yearly imagery Extract summary information from segments Extract spectral trajectories for pixels Statistically identify and fit segments with consistent trends (Kennedy et al., OSU)

Integration for Regional Mapping of Terrestrial Carbon Terrestrial Carbon Modeling SINKS SOURCES Biosphere CO2 Flux Observations Inventories Carbon Stocks Maps of Terrestrial Carbon Stocks and Fluxes Understanding of terrestrial carbon processes Spatial data: Land-use, land cover, meteorology (Law et al. 2006)
