East Asian methane emissions inferred from high-resolution inversions of GOSAT and TROPOMI observations: a comparative and evaluative analysis

Abstract: Abstract. We apply atmospheric methane column retrievals from two different satellite instruments (GOSAT and TROPOMI) to a regional inversion framework to quantify East Asian methane emissions for 2019 at 0.5° × 0.625° horizontal resolution. The goal is to assess if GOSAT (relatively mature but sparse) and TROPOMI (new and dense) observations inform consistent methane emissions from East Asia. Comparison of the results from the two inversions show similar correction patterns to the prior inventory in Central N… Show more

“…It has a unique capability for high-resolution quantification of national emissions and effectively attributing emissions to sectors. This capability has recently been demonstrated for North America (Zhang et al, 2020;Shen et al, 2021Shen et al, , 2022 and East Asia (Chen et al, 2022;Liang et al, 2022).…”
