摘要
对MALT-CLS方法在大气痕量气体FTIR定量分析中的应用进行了研究,介绍了一些定量分析的实验,如长光程怀特池、机载被动遥测。该方法的特点是其校准光谱是采用MALT程序通过计算HITRAN数据库中吸收线参数、环境参数和仪器参数而得到。它尤其适用于无法采用样品池来产生校准光谱的长光程开放光路和以太阳、天空、地物为背景的被动FTIR测量。
The MALT-CLS method for quantitative analysis of atmosphere trace gas by FTIR spectrometry was studied. Some experiments are described, such as long-path White cell, and passive remote sensing of aircraft. The characteristic of this method is that the calibration spectra are calculated from a database of absorption line parameters HITRAN using MALT program, including environmental and instrumental effects in the calculation. It is particularly useful in long open-path and solar FTIR spectroscopy, or passive remote sensing by FTIR.
