This note describes measurements of the mass-specific extinction coefficient, s, of carbonaceous aerosol produced during hydrocarbon combustion. Measurements of s were obtained by laser extinction at = 632nm. The aerosol was generated using a laminar diffusion flame, and the mass-specific extinction coefficient determined as a function of the global equivalence ratio, . The elemental carbon content of the aerosol was also determined with respect to . A relationship was developed between the… CONTINUE READING
