摘要: 为了研究机场排放对环境大气的影响,在2014年12月10日到16日,采用掩日通量遥测傅里叶红外技术(SOF-FTIR)对某国际机场的乙烯(C2H4),己烷(C6H14)和一氧化碳(CO)排放进行了研究。分析了三种组份的特征浓度值及其变化趋势,结果表明三者的特征浓度值变化趋势上具有高度相关性;机场乙烯的平均柱浓度为13.18ppmm,己烷的平均柱浓度为97.82ppmm,一氧化碳的平均柱浓度为3065.56ppmm。通过结合国际民航组织(ICAO, International Civil Aviation Organization)发布的测量数据,得到某国际机场乙烯和己烷的排放量分别达到碳氢化合物排放总量的3.32%和66.96%。文章结果表明,掩日通量遥测FTIR技术与ICAO的数据具有较好的一致性,为评估飞机排放提供数据支撑。

Abstract: To study the impact of emissions at an airport on local air quality, a measurement campaign at the Beijing Capital International Airport was performed from 10 December 2014 to 16 December 2014. Measurements of, CO,C2H4 and C6H14 were conducted with solar occulation flux -fourier transform infrared spectrometer (SOF-FTIR) system to determine real in-use emission indices of aircraft . The characteristic concentration values of three target gas were analyzed .The results shows that there was a high correlation between them and the average column concentration of ethylene, hexane and Carbon monoxide in the airport are 13.18ppmm 97.82ppmm , 3065.56ppmm, separately. By combining the measurement data released by ICAO, it can be concluded that the emissions of ethylene and hexane at an international airport have reached the levels of total hydrocarbon emissions 3.32% and 66.96%, respectively. The results show that the SOF-FTIR technology has good consistency with ICAO data and provides technical support for the assessment of aircraft emissions.
