抽象的。这项工作报告了2004年至2011年期间利用大气化学实验傅里叶变换光谱仪(ACE-FTS)进行的太阳掩星测量对地球大气中乙腈(CH 3 CN)的首次红外卫星遥感测量。检索方案使用乙腈的新定量实验室光谱测量(Harrison和Bernath,2012)。虽然个别ACE-FTS剖面测量主要受测量噪声影响,但10°纬度箱中的中值剖面显示,体积混合比从11.5 km处的约150 ppt(万亿分之一)稳步下降到11.5 km处的约150 ppt(万亿分之一)。
Abstract. This work reports the first infrared satellite remote-sensing measurements of acetonitrile (CH 3 CN) in the Earth's atmosphere using solar occultation measurements made by the Atmospheric Chemistry Experiment Fourier transform spectrometer (ACE-FTS) between 2004 and 2011. The retrieval scheme uses new quantitative laboratory spectroscopic measurements of acetonitrile (Harrison and Bernath, 2012). Although individual ACE-FTS profile measurements are dominated by measurement noise, median profiles in 10° latitude bins show a steady decline in volume mixing ratio from ~150 ppt (parts per trillion) at 11.5 km to
