Fig. 1From: Implications of overestimated anthropogenic CO2 emissions on East Asian and global land CO2 flux inversionMaps of CO2 inversion regions (54 land and 30 ocean; shaded) and atmospheric observation network (circle) with mostly surface sites, except for the Japan AirLines (JAL) flight track between Tokyo and Sydney/Brisbane. The snow-covered (zero flux) Antarctica and Greenland are not optimized by the inversion system. The CH4 inverse model solves for emissions from 53 land only regions (1 region less in the Southeast Asia; ref. Patra et al. 2016b)Back to article page
