Quantification of carbon dioxide and methane emissions in urban areas: source apportionment based on atmospheric observations

Abstract: Anthropogenic emissions of carbon dioxide (CO 2) and methane (CH 4) in the atmosphere constitute an important component of the related carbon budget. The main source of anthropogenic CO 2 is burning of fossil fuels, especially in densely populated areas. Similar emissions of CH 4 are associated with the agricultural sector, coal mining, and other human activities, such as waste management and storage and natural gas networks supplying methane to large urban, industrial centers. We discuss several methods aimed… Show more

“…edu/influx/) are good examples. For Poland, a coordinated effort with existing observation projects such as Zimnoch et al (2018) (radiocarbon measurements at Krakow) and Messerschmidt et al (2012) (upward looking FTIR at Białystok) provide a starting point to approach emission uncertainty using a top-down vs. bottom-up approach. Such efforts need to be supported for a long term for monitoring purpose.…”

“…The papers by Lesiv et al (2018), Oda et al (2019), and Zimnoch et al (2018) explore the use of additional, ideally independent, observations as top-down constraints, such as atmospheric measurements and remote sensing, to identify and close potential inaccuracies in bottom-up inventories. Although, all three papers exercise bottom-up/top-down, high-resolution, or gridded, at subglobal scales, they show potential to expand to global scales-which is why, arguably, there are still some degrees of freedom in closing (verifying) bottom-up and topdown.…”

“…However, as noted by the authors, such a request would need to accompany concerted global actions, ranging from the collection and reporting of data, through monitoring, to international governance. Zimnoch et al (2018) focus on top-down estimation of both CO 2 and CH 4 emissions from the urban area of Krakow, Poland. They present a set of methods based on atmospheric observations of CO 2 and CH 4 mixing ratios and their isotopic composition, the use of additional data relating to the atmospheric concentration of radon and mixing layer height, and atmospheric modeling, to identify and quantify urban emissions.…”

“…Sumber alami gas-gas ini adalah proses geologi termasuk proses vulkanik, serta proses-proses alami yang terjadi di hutan, danau, daratan dan laut. Sedangkan sumber antropogenik kedua gas ini dari kegiatan industri, penggunaan bahan bakar fosil, pertanian (terutama untuk CH 4 ) serta limbah industri dan rumah tangga, (Khan et al, 2007;Zimnoch et al, 2018).…”
