Some types of gaseous pollution sources, particularly extended area industrial complexes and those producing hot combustion products, cannot be monitored adequately with conventional point sampling methods. To aid in characterizing emissions from and in developing remote sensing methods for application to such sources, a high-resolution (0.06/cm) infrared spectrometer system has been installed in a van. This system can be used with a remote light source to make longpath absorption measurements in the atmosphere or can be used in a single-ended mode to obtain emission spectra of hot gases. Initial measurements were made across a fertilizer plant gypsum pond; hydrogen fluoride was measured in the 10-50 ppb range. Measurements at an oil refinery showed propylene, ethylene, methanol, other hydrocarbons, sulfur dioxide, and carbon monoxide in ppb to ppm levels. Jet engine emissions were also evaluated. The measurement system is described and data from the above three measurement programs are presented.
