RÉSUMÉ

The optical properties of urban aerosol particles are calculated using exact methods at 910 nm wavelength under different assumptions about particle composition and shape. Results show that spherical particles backscatter light on the average about 40 percent more than the corresponding nonspherical particles, the difference generally being larger for larger particles. In contrast, changing the particle composition from water to silicate increases backscattering by about a factor of three. Typical values for absorptivity seem to have negligible impact on backscattering.
