Abstract

There is a need by civilian and government agencies for a means of passively detecting and measuring trace gases from remote sites. The techniques described in this paper may be used for remote monitoring of: adherence to environmental standards and regulations, process control, and local and global environmental conditions. Using an emission Fourier Transform Spectrometer (FTS) coupled with our Orthogonal Background Suppression (OBS) techniques we have been able to quantitatively measure the column density (n_c) of trace gases in simulations and controlled releases under strong background conditions.
