中国的第十二个五年计划包括污染控制措施，目标是到2015年将全国氮氧化物（NOx）排放量比2010年减少10%。采用多元线性回归分析方法，对中国18个NO2热点地区臭氧监测仪（OMI）11年的NO2像元数据进行分析。回归分析考虑了气象学、像素分辨率、季节效应、工作日变化和年与年之间的变化。NO2趋势表明，从2005年到2011年左右，大部分地区的NO2柱都有所增加，随后在2015年持续大幅下降。卫星结果与截至2014年的年度官方氮氧化物排放清单一致。这表明了利用卫星检索评价排放清单趋势的价值。它进一步表明，最近的控制策略是有效的，在减少排放量和最近的经济转型，在中国可能会对NO2柱的影响。2015年的卫星信息表明，自最新的清单以来，排放量继续减少，并已超过“十二五”规划的目标。
China’s twelfth Five-Year Plan included pollution control measures with a goal of reducing national emissions of nitrogen oxides (NOx) by 10% by 2015 compared with 2010. Multiple linear regression analysis was used on 11-year time series of all nitrogen dioxide (NO2) pixels from the Ozone Monitoring Instrument (OMI) over 18 NO2 hotspots in China. The regression analysis accounted for variations in meteorology, pixel resolution, seasonal effects, weekday variability and year-to-year variability. The NO2 trends suggested that there was an increase in NO2 columns in most areas from 2005 to around 2011 which was followed by a strong decrease continuing through 2015. The satellite results were in good agreement with the annual official NOx emission inventories which were available up until 2014. This shows the value of evaluating trends in emission inventories using satellite retrievals. It further shows that recent control strategies were effective in reducing emissions and that recent economic transformations in China may be having an effect on NO2 columns. Satellite information for 2015 suggests that emissions have continued to decrease since the latest inventories available and have surpassed the goals of the twelfth Five-Year Plan.
