Fig. 2: Monthly averaged XCH₄ in the region of interest (ROI) of Southeast China and the latitudinal zone centered on the ROI according to Zeng et al.².

a The MODIS-based paddy rice map at 0.5° resolution in monsoon Asia in 2010. The orange rectangle shows the latitudinal zone of 23°–33°N centered on the Southeast China ROI. The blue rectangle shows the boundary of the Southeast China ROI from Zeng et al.². b Monthly averaged XCH₄ in the ROI and the latitudinal zone according to Zeng et al.². The regional mean in b is the averaged value of XCH₄ in ROI, and the zonal mean in b is the averaged XCH₄ over the latitudinal zone centered on the ROI, which is from Zeng et al.’s paper².
