The aim of this paper is to investigate the evolution of SO and NOx emissions of ten very large combustion plants (LCPs >500 MW) located in the European Union (EU) during 2005-2015. The evolution of NOx and SO emissions were analyzed against the EU Directives in force during 2005-2015. The investigation was performed using space-borne observations and estimated emissions collected from the EEA (European Environment Agency) inventory of air pollutant emissions. The power plants were chosen according to their capacity and emissions, located in various parts of Europe, to give an overall picture of atmospheric pollution with NOx and SO associated with the activity of very large LCPs in Europe. Satellite observations from OMI (Ozone Monitoring Instrument) are compared with calculated emissions in order to assess whether satellite observations can be used to monitor air quality, as a standard procedure, by governmental or nongovernmental institutions. Our results show that both space observations and estimated emissions of NOx and SO atmospheric content have a descending trend until 2010, complying with the EU Directives. The financial and economic crisis during 2007-2009 played an important role in reducing emissions.
本文旨在研究欧盟（EU）地区 2005-2015 年间十个特大型燃烧厂（LCPs >500MW）的 SO 和 NOx 排放演变情况。针对 2005-2015 年期间生效的欧盟指令，对 NOx 和 SO 排放的演变情况进行了分析。该研究使用了星载观测和欧洲环境署（eea）空气污染排放清单中收集的估算排放量进行了分析。选择这些电厂是根据其容量和排放量，并分布在欧洲各地，以便全面了解与欧洲特大型 LCPs 活动相关的大气中 NOx 和 SO 污染情况。将 OMI（臭氧监测仪）卫星观测与计算排放量进行了比较，以评估卫星观测是否可作为一种标准程序，由政府或非政府机构用于监测空气质量。我们的结果表明，直到 2010 年，NOx 和 SO 大气含量的空间观测和估算排放量均呈下降趋势，符合欧盟指令的要求。2007-2009 年的金融危机在减排方面发挥了重要作用。
