  • CH 4 and CO emission estimates for megacities: Deriving enhancement ratios of CO 2 , CH 4 , and CO from Gosat-2 observations

    Open Access•Hirofumi Ohyama, Yukio Yoshida et al.•ARTICLE•Environmental Research Letters•2024

    Enhancement ratios among trace gases co-emitted by combustion of fossil fuels vary with emission sources and their combustion efficiency. We used column-averaged dry-air mole fractions of carbon dioxide (XCO 2 ), methane (XCH 4 ), and carbon monoxide (XCO) from the Greenhouse gases Observing SATellite-2 (GOSAT-2), a unique satellite that observes them simultaneously with the same field of view, to derive the enhancement ratios (ΔXCO/ΔXCO 2 , ΔXCO…
