• Abstract:
  Aircraft emissions are a growing concern for the FAA, airports, and the community. U.S.
  
  and international air quality models were previously unable to accurately predict initial
  
  plume dispersion and the resulting pollutant concentrations because the characteristics of
  
  the initial plume behavior were virtually unknown. These data are needed as input to
  
  dispersion models, such as the FAA’s Emissions and Dispersion Modeling System
  
  (EDMS), for use in complying with air quality requirements. Since very little research
  
  had been done in this area, input values previously used were primarily based on the best
  
  available information and good engineering judgment. The Volpe National
  
  Transportation Systems Center, FAA’s Office of Environment and Energy (AEE), the
  
  National Oceanic and Atmospheric Administration (NOAA), and the Los Angeles
  
  International Airport (LAX), teamed up to conduct a study of aerosol plume behavior
  
  from jet exhaust using LIght Detection And Ranging or LIDAR. LIDAR has been used
  
  for previous measurements to study wing-tip vortices and some pollutant evaluations near
  
  airports, and was concluded to be appropriate for this application. In support of AEE, the
  
  John A. Volpe National Transportation Systems Center initiated action to conduct the
  
  research. Volpe enlisted the assistance of the NOAA, based on their large amount of
  
  experience with LIDAR. NOAA has several LIDAR units and the flexibility to reengineer
  
  the units and associated software on a project-by-project basis making them the
  
  perfect fit for this team. Setup and measurements occurred from May 14 through 24,
  
  2001. The results of the measurements have exceeded expectations allowing
  
  quantification of aircraft plume rise and initial dispersion parameters (standard
  
  deviations) at this major urban airport. This paper will summarize the methodology,
  
  results and conclusion of this project.
