Abstract

Recent developments in atmospheric monitoring with a ground-based FTIR spectrometer are presented. Several aspects of the inversion method for the retrieval of temperature and humidity profiles from IR emission spectra are reported. The main objective of the study is the evaluation of the retrieval method as a support in pollution monitoring by FTIR emission spectroscopy. Through an analysis of recent experimental results the accuracy of predicting experimental signature of pollutants with retrieved profiles is established. The possibilities of the method are illustrated by the evaluation of CFC-11 and CFC-12 mixing ratios from a typical radiance measurement.
