英文摘要 | Optimized biogenic carbon fluxes for Europe were estimated from high-resolution regional-scale inversions, utilizing atmospheric CO2 measurements at 16 stations for the year 2007. Additional sensitivity tests with different datadriven error structures were performed. As the atmospheric network is rather sparse and consequently contains large spatial gaps, we use a priori biospheric fluxes to further constrain the inversions. The biospheric fluxes were simulated by the Vegetation Photosynthesis and Respiration Model (VPRM) at a resolution of 0.1 degrees and optimized against eddy covariance data. Overall we estimate an a priori uncertainty of 0.54 GtC yr(-1) related to the poor spatial representation between the biospheric model and the ecosystem sites. The sink estimated from the atmospheric inversions for the area of Europe (as represented in the model domain) ranges between 0.23 and 0.38 GtC yr(-1) (0.39 and 0.71 GtC yr(-1) up-scaled to geographical Europe). This is within the range of posterior flux uncertainty estimates of previous studies using ground-based observations. |
