Abstract

Methane emissions from natural gas production are of increasing importance as they threaten efforts to mitigate climate change. Current inventory estimates carry high uncertainties due to difficulties in measuring emission sources across large regions. Satellite measurements of atmospheric methane could provide new understanding of emissions. This paper provides insight into the effectiveness of using satellite data to inform and improve methane inventories for natural gas activities. TROPOMI data are used to quantify methane emissions from natural gas within the Montney basin region of Canada and results are compared with existing inventories. Emissions estimated using TROPOMI data were 2.6 ± 2.2 kt/day which is 7.4 ± 6.4 times the inventory estimates. Pixels (7 by 7 km) that contained gas facilities had on average 11 ppb more methane than the background. 7.4% of pixels containing gas sites displayed consistently high methane levels that were not reflected in the inventory. The satellite data were not sufficiently granular to correlate with inventories on a facility scale. This illustrates the spatial limitations of using satellite data to corroborate bottom-up inventories.

比较卫星甲烷测量和库存估算:一个加拿大的案例研究
天然气生产产生的甲烷排放越来越重要,因为它们威胁到减缓气候变化的努力。由于难以测量大区域的排放源,目前的库存估算具有很高的不确定性。大气甲烷的卫星测量可以提供对排放的新认识。本文介绍了利用卫星数据为天然气活动提供信息和改进甲烷库存的有效性。TROPOMI数据用于量化加拿大Montney盆地地区天然气的甲烷排放量,并将结果与现有库存进行比较。使用TROPOMI数据估计的排放量为2.6±2.2 kt/天,是库存估计的7.4±6.4倍。含有天然气设施的像素(7乘7公里)比背景平均多11ppb的甲烷。7.4%含有气体点的像素显示出持续的高甲烷水平,这在库存中没有反映出来。卫星数据不够细,无法与设施规模的库存相关联。这说明了使用卫星数据来证实自下而上的清单的空间局限性。
