Short summary

There is an on-going debate on the larger European biospheric uptake inferred from GOSAT X_CO₂ retrievals than those inferred from in situ data. Using a set of 15 experiments, we found that the elevated uptake over Europe could largely be explained by mis-fitting data due to regional X_CO₂ biases: 50–80 % of the elevated European uptake is due to retrievals outside the immediate European; and a varying monthly bias of up to 0.5 ppm for X_CO₂ retrievals over Europe could explain most of the remainder.
