Regional CO2 Fluxes for North America Estimated from NOAA/CMDL Observatories Date: Tuesday, September 27 @ 15:45:00 MDT Topic: The Fate of Fossil-Fuel Emissions By Wouter Peters We present an analysis of terrestrial net CO2 fluxes from North America for the period 2000-2004. These fluxes consist of hourly maps at ~70km×100km resolution that are consistent with observed atmospheric CO2 mixing ratios, as well as with varying climatic conditions across different ecosystems as observed from space. The flux maps are created in a newly developed ensemble data assimilation system that consists of the atmospheric Transport Model v5 (TM5), the Vegetation Photosynthesis Respiration Model (VPRM), and an efficient Bayesian least-squares algorithm to optimize the fluxes from different biomes in VPRM against CO2 mixing ratios from the NOAA-CMDL observing network. The stochastic nature of the ensemble data assimilation system allows us to consistently include uncertainty on net CO2 fluxes from the neighboring oceans and more distant continents in the flux estimates for North America.
