Human Activity Drives Growth of Methane Concentrations in the Atmosphere

Distributions of emission corrections by inversion (a), XCH4 based on the GOSAT NIESv2.72 data (Yoshida et al., Atmos. Meas. Tech., 2013) (b). The XCH4 values are gridded at 2.5 x 2.5 degrees. The 2 panels on the right column show a priori model - GOSAT differences (c), and a posteriori model - GOSAT differences (d), suggesting an overestimation of CH4 emissions by inventory method in the large areas of the northern hemisphere.
