Description:
A commercial Fourier transform interferometer system with telescopic optics has been installed in a van and used to make long-path absorption and single-ended emission measurements of gaseous pollutant concentrations at a number of geographical locations. The system covers the infrared spectral region from 650 to 6000/cm at a maximum resolution of 0.06/cm. For many pollutants, concentrations in the 1-10 parts per billion range can be detected over a 1 kilometer path length. To date, measurements have been made in the absorption mode across fertilizer plant gypsum ponds, an oil refinery, and jet engine plumes; industrial stacks, waste gas flares, and jet engine plumes have been studied in the emission mode.
