Simulations for a correlative space- and ground-based experiment for detection of trace gases by FTIR spectroscopy

The detection the minor gaseous constituents and the determination of their concentration is important in the study of the Earth's environment. These components can play a substantial role in the atmospheric processes leading even to breaking down the ecological equilibrium. Mid- and long- term observations form ground and from space are necessary to monitor sudden changes and to investigate the long-term trends in the composition of the atmosphere. We propose here a space-ground correlative experiment which gives new possibilities. Simulation of solar absorption spectra of the trace gases in the Earth's atmosphere in 2-16 micrometers spectral range for both types of measurements are presented.© (1996) COPYRIGHT SPIE--The International Society for Optical Engineering.
