The quantification of nitrogen oxide (NO) emissions is critical for air quality modeling. Based on updated fuel consumption and emission factor databases, a global emission inventory was compiled with high spatial (0.1° × 0.1°), temporal (monthly), and source (87 sources) resolutions for the period 1960 to 2014. The monthly emission data have been uploaded online ( http://inventory.pku.edu.cn ), along with a number of other air pollutant and greenhouse gas data for free download. Differences in source profiles, not global total quantities, between our results and those reported previously were found. There were significant differences in total and per capita emissions and emission intensities among countries, especially between the developing and developed countries. Globally, the total annual NO emissions finally stopped increasing in 2013 after continuously increasing over several decades, largely due to strict control measures taken in China in recent years. Nevertheless, the peak year of NO emissions was later than for many other major air pollutants. Per capita emissions, either among countries or over years, follow typical inverted U-shaped environmental Kuznets curves, indicating that the emissions increased during the early stage of development and were restrained when socioeconomic development reached certain points. Although the trends are similar among countries, the turning points of developing countries appeared sooner than those of developed countries in terms of development status, confirming late-move advantages.
氮氧化物（NO）排放量的量化对于空气质量建模至关重要。本研究基于最新的燃料消耗和排放因子数据库，编制了 1960 年至 2014 年期间具有高时空（0.1°×0.1°，每月）和源解析度（87 个源）的全球排放清单。每月的排放数据已在线上传（http://inventory.pku.edu.cn），并可免费下载其他一些空气污染物和温室气体数据。我们的结果与之前报告的结果在源谱方面存在差异，而不是全球总量方面存在差异。各国之间的总排放量、人均排放量和排放强度存在显著差异，尤其是发展中国家和发达国家之间。全球范围内，NO 排放量在经过几十年的持续增长后，终于在 2013 年停止增长，这主要是由于近年来中国采取了严格的控制措施。然而，NO 排放的峰值年份晚于许多其他主要空气污染物。无论是国家之间还是多年之间，人均排放量都遵循典型的倒 U 型环境库兹涅茨曲线，表明排放量在发展初期增加，而在社会经济发展达到一定水平时受到限制。尽管各国的趋势相似，但发展中国家在发展状况方面的转折点早于发达国家，证实了后发优势。
