A series of measurements of jet engine emissions were conducted in an airport environment using several infrared gas-filter correlation (GFC) instruments and a high resolution Fourier-transform infrared (FTIR) spectrometer system. The GFC instruments were shown to be suitable for measuring CO concentrations in the general airport environment and across the exhaust of a stationary jet. Attempts to determine jet plume rise velocity from the GFC data were unsuccessful. The FTIR system was used to make both absorption and emission measurements on single jets and to make long-path absorption measurements in the general airport environment. Species observed in the single jet absorption measurements were CO (28 ppm), formaldehyde (1 ppm), ethylene (3.2 ppm), and cumulative hydrocarbons (8.6 ppm hexane equivalent). This report describes the instrumentation and the measurement programs and gives some recommendations for additional work. (Author)
