我们使用 MOPITT(对流层污染测量)仪器的 CO 反演,对 2000 年不同地理区域和不同来源类别的 CO 排放量进行综合反演。我们发现我们对亚洲化石燃料/生物燃料(FFBF)使用的二氧化碳排放量的自上而下的估计与最近自下而上的估计之间存在很大差异。这项研究的一个关键结论是,东亚 (EAS) 的二氧化碳排放量比最近自下而上的估计高出约 1.8-2 倍。
We present a synthesis inversion of CO emissions from various geographical regions and for various source categories for the year 2000 using CO retrievals from the MOPITT (Measurements of Pollution in the Troposphere) instrument. We find a large discrepancy between our top-down estimates and recent bottom-up estimates of CO emissions from fossil fuel/biofuel (FFBF) use in Asia. A key conclusion of this study is that CO emissions in East Asia (EAS) are about a factor of 1.8-2 higher than recent bottom-up estimates.
