Presentation Transcript

  1. 2007 ChEAS meeting SiB-RAMS/LPDM modeling for evaluating regional scale CO2 fluxes Marek Uliasz, Colorado State University

  2. global CO2 - PCTM

  3. global CO2 - PCTM SiB-RAMS

  4. global CO2 - PCTM SiB-RAMS LPDM

  5. global CO2 - PCTM SiB-RAMS LPDM influence functions for concentrations and flux measurements

  6. Influence functions for 31 towers for 30 day sampling period starting June 9, 2004 (passive tracer)

  7. respiration flux

  8. fossil fuel flux

  9. assimilation flux

  10. WLEF 30m WLEF 396m

  11. WLEF 30m WLEF 396m

  12. Effect of local and distanst CO2 fluxes

  13. WLEF 396m

  14. How big area around the WLEF need to be considered to allow surface CO2 fluxes to catch a larger scale concentration variability? • 50 km? • 500 km? • 1000 km? • Go global?

  15. Tracer residence time [days] for different towers in 5800x3400 km modeling domain over continental US derived from SiB-RAMS/LPDM simulations for 30 day period (June 9 - July 8, 2004) 0 20 days

  16. CO2 at 396m WLEF tower influence functions analysis for 600x600kn domain

  17. time independent corrections to be estimated from concentration data for each inversion cycle respiration & assimilation fluxes simulated by SiB-RAMS

  18. Implementation for a given inversion cycle k – index over observations (sampling times and towers) i – index over source areas (grid cells)
