Extinction (σext) (a), scattering (σsca) (b), and absorption-specific (σabs) (c) cross-sections of soot particles with a fresh mobility diameter of 320 nm. The filled and open symbols correspond to the optical properties of fresh and sulfuric acid-coated soot particles, respectively. The vertical error bars represent random error of the measurements (2 SDs), and the values are averaged over at least three measurements.
