中国1996-2003年的煤炭消费量数据与三种官方能源统计数据、《中国能源统计年鉴》（PBP-CESY）的分省数据、国际能源署（IEA 2004）的能源平衡表[2004，Energy Statistics of Non-OECD Countries]存在较大差异。IEA，巴黎]，以及《中国能源统计年鉴》（CT-CESY）中的国家总计数据。利用入江等报道的中国北方平原对流层NO2柱密度的GOME卫星观测数据对这些数据进行了验证[2005，东亚上空GOME获得的长期对流层NOx数据的评价1996-2002. Geophysical Research Letter 32（11）L 118 10，doi：10.1029/2005GL022770]和Richter等人[2005，Increase in tropospheric nitrodioxide over China observed from space. Nature 437，129-130]。两份报告从1996年到2002年NO2柱平均增加约50%，而基于PBP-CESY和IEA 2004的NOx排放量增加分别为25%和15%，CT-CESY的增幅更低。卫星数据和PBP-CESY排放清单之间的增长趋势差异可能在不确定性范围内，但有一个保留意见，即PBP-CESY燃料总消费量的增长可能仍然被低估，特别是在1999年之后。利用IEA 2004和CT-CESY统计数据计算的1996-2002年NOx排放增长率明显低估，超出了卫星观测的不确定性水平，建议不要将其用于中国1996-2002年的排放清单研究。(c)2006年由Elsevier Ltd.出版
There is substantial difference in the coal consumption data in China during 1996-2003 among the three official energy statistics, the province-by-province data in the China Energy Statistics Yearbook (PBP-CESY), the energy balance tables by International Energy Agency (IEA2004) [2004, Energy Statistics of Non-OECD Countries. IEA, Paris], and the country-total data in the China Energy Statistics Yearbook (CT-CESY). Verification of these data was made by GOME satellite observational data for tropospheric NO2 column density in Northern China Plain reported by Irie et al. [2005, Evaluation of long-termtropospheric NOx data obtained by GOME over East Asia in 1996-2002. Geophysical Research Letter 32(1 1) L 118 10, doi: 10.1029/2005GL022770] and Richter et al. [2005, Increase in tropospheric nitrogen dioxide over China observed from space. Nature 437, 129-130]. The NO2 column increase from 1996 to 2002 averaged for the two reports is about 50%, whereas the NOx emission increases based on the PBP-CESY and IEA2004 are 25% and 15%, respectively, and that for CT-CESY is even lower. The discrepancy of the increasing trends between the satellite data and the PBP-CESY emission inventory could be within the uncertainty level with a reservation that the increase in total fuel consumption in PBP-CESY may still be underestimated particularly after the year of 1999. The increasing rates of NOx emissions during 1996-2002 calculated by using the IEA2004 and CT-CESY statistics are apparently underestimated beyond the uncertainty level of the satellite observation, and they are recommended not to be used for emission inventory studies in China during the period.
