Many aircraft and launch vehicles that use Jet A1 as a fuel operate at high altitudes and emit large amounts of particulate matter into the atmosphere. The impact of particulate matter is steadily increasing and requires continuous monitoring and source reduction efforts. Morphological and optical characterization data of PM can be used in concentration measurement and reduction techniques to help quantitatively analyze the damage caused by PM. In this study, dimensionless light extinction coefficient measurements and morphological analysis of PM produced from burning Jet A1 in a coaxial flow burner were performed. The values of fractal dimension and prefactor which can help to quantify the morphological properties of the aggregates of Jet A1 PM, were found to be 1.68 and 2.85, respectively. The scattering albedo value estimated from the morphological properties was 0.094, indicating that the contribution of scattering to the total extinction was about 10%. The results were strongly supported by the fact that the fraction of elemental carbon (EC) composed of PM is dominant compared to organic carbon (OC). These empirical results highlighted that the light extinction by Jet A1 PM was dominated by the effects of light absorption rather than those of light scattering.
