Description:
Northern Eurasia is one of the largest terrestrial carbon reservoirs on the Earth’s surface. However, since the coverage of surface CO 2 observations is still limited, the response to the climate variability remains uncertain. We estimated monthly CO 2 fluxes for three sub-regions in Northern Eurasia (north of ∼60°N), Northeastern Europe, Western Siberia and Eastern Siberia, using CO 2 retrievals from the Japanese Greenhouse Gases Observing SATellite (GOSAT). The variations of estimated CO 2 fluxes were examined in terms of the regional climate variability, for the three consecutive growing seasons of 2009–2011. The CO 2 fluxes estimated using GOSAT data are highly correlated with the surface temperature anomalies in July and August ( r 〉 0.8) while no correlation is found in the CO 2 fluxes estimated only using surface observations. The estimated fluxes from GOSAT data exhibit high negative correlations with o...
