Abstract
Carbon dioxide (CO2) fluxes over the temperate Eura-sian region have been estimated robustly for the period 2006-2008 using the time-dependent inversion com-ponent of the TRANSCOM protocol. Data from six CO2 measuring stations in temperate Eurasia, includ-ing the Indian station at Hanle along with 75 others from different parts of the world have been used. A careful analysis of a posteriori errors and model reso-lution shows that temperate Eurasia is a major resid-ual sink of CO2 with a value of 1.5 Gigatonnes of carbon/year.
