Megacity Mumbai is a non-attainment city designated under the National Clean Air Programme (NCAP) of the Government of India, where the identification of exact sources responsible for air quality issues remains unclarified. In the present work, an effort has been made to develop an ultra-fine resolution (∼400mt × ∼400mt) emission inventory by including micro-level activity data for both organized and unorganized sources using a bottom-up approach for the year 2020. The estimated results unveil that 44 Gg/yr of PM, 72.5 Gg/yr of PM, 359.7 Gg/yr of CO, 175.6 Gg/yr of NO, 132.9 Gg/yr of SO, 223.4 Gg/yr of VOC, 13 Gg/yr of BC and 12.5 Gg/yr of OC have been deteriorating the city air. The developed inventory is most up-to-date surface emission dataset highlighting the hotspots along with the source-specific contributions. This study targets mitigation for cleaner air in the megacity; an aid to the mission of the NCAP. In addition to this, the present dataset could be an important tool for public health management and air quality studies.

制定排放清单，用于印度人口最多的大城市孟买的空气质量评估和缓解策略

特大城市孟买是印度政府国家清洁空气计划 (NCAP) 指定的未达标城市，造成空气质量问题的确切来源仍不清楚。在目前的工作中，我们采用自下而上的方法，通过包含有组织和无组织来源的微观活动数据，努力开发超精细分辨率（∼400mt × ∼400mt）排放清单。估算结果显示，PM 44 Gg/年、PM 72.5 Gg/年、CO 359.7 Gg/年、NO 175.6 Gg/年、SO 132.9 Gg/年、VOC 223.4 Gg/年、13 Gg/年BC 省每年 12.5 克/OC 每年 12.5 克，导致城市空气质量恶化。开发的清单是最新的表面排放数据集，突出了热点以及特定源的贡献。这项研究的目标是缓解大城市的空气污染问题；对 NCAP 使命的帮助。除此之外，目前的数据集可以成为公共卫生管理和空气质量研究的重要工具。
