AB: A number of global carbon balance studies suggested that there is very likely a large carbon sink in the northern Hemisphere, but its spatial patterns and temporal dynamics remain uncertain. International research communities have recently made great efforts establishing a network of CO2 eddy flux towers across boreal forests in Northern Eurasia. The eddy flux tower network has produced and will continue to produce rich data sets of net ecosystem exchange of CO2 (NEE) at the sites. The arisen challenge is how to interpret the rapidly accumulated data sets, and how to upscale the observations into regional scale to explain the global C imbalance. In this presentation, we will introduce a new NASA-funded project that integrates the eddy tower observation, remote sensing analysis, and biogeochemical modeling for quantifying CO2 fluxes of boreal forests in Russia. We will also present some preliminary results from the satellite-based Vegetation Photosynthesis Model (VPM) model and the process-based DNDC model for boreal forests in Europe and North America.
