摘　　要：遥感傅里叶变换红外光谱(RS-FTIR)是当前大气环境监测中的一种重要手段,它具有灵敏度高,选择性好,不需取样和样品的预处理,能够同时监测多种化合物,能提供远距离实时自动监测的优点,适用于大气有毒易挥发有机化合物(VOCs)的定性、定量测定和遥感实时动态监测。文章综述了南京理工大学现代光谱研究室近几年来在RS-FTIR大气环境监测领域的研究进展,包括化学计量学,计算机层析(CT),FTIR谱图解析,大气污染物空间浓度分布监测,被动式遥感监测等方面的最新研究成果。这些研究成果充分表明,遥感FTIR技术的快速发展和应用,促进了分析化学在时空上的延伸,在大气环境监测领域中必将有更广泛的应用前景。Remote sensing FTIR（RS-FTIR） is one of the most important technologies in atmospheric pollutant monitoring. It has several prevailing advantages： （1） high resolution and high selectivity; （2） it requiring no sampling and no sample preprocessing; （3） capability of detecting several compounds simultaneously; （4） real time, long distance, and automatic monitoring. So it is extraordinarily appropriate for the quantitative and qualitative determination, and remote, real time, dynamic monitoring of air contaminant, especially the toxic volatile organic compounds （VOCs）. The present paper reviews the research progress in remote sensing FTIR for air monitoring made by the Laboratory of Advanced Spectroscopy in recent years, including chemometrics, computed tomography, FTIR spectra interpretation, spatial distribution of air pollutant concentration and passive remote monitoring, etc. These research findings show that the rapid development and application of remote sensing FTIR accelerated the temporal and spatial extension of analytical chemistry, and it will by all means have wide prospects in atmospheric environmental monitoring.
