摘要

相关光谱学是测定和监测痕量大气污染物的一种强大的诊断工具，它涉及到大气特定区域的“场光谱”特征与代表感兴趣的分子物种的光谱吸收特征的“掩模函数”特征之间的相关比较。这些之间的相关程度可以定量地解释为仪器视野中感兴趣的物种的柱密度的直接测量。

GASCOSCAN and GASCOFIL-Remote Sensing Gas Correlation Spectrometers for Tropospheric Trace Gas Measurements

Correlation spectroscopy, which is a powerful diagnostic tool for the determination and monitoring of trace atmospheric contaminants, involves a correlative comparison between the features of a "field spectrum" of a specific region of the atmosphere, and the features of a "mask function" which is representative of the spectral absorption features of the molecular species of interest. The degree of correlation between these can be interpreted quantitatively as a direct measure of the column density of the species of interest in the instrumental field of view.
