Abstract

The scattering effects of aerosols were observed during the New Year celebration last December 31, 2005 to January 01, 2006. The forward scattering intensity from a Xenon lamp was observed using a digital spectrometer that was connected to computer. The results showed that from 18:30 to 21:00, as the concentration of the fine particulates increased from 1.2 µgm⁻³ to 6.0 µgm⁻³, the mass extinction efficiency (MEE) increased from 1 − 20 m²g⁻¹. This indicates that fine particulates can change significantly the optical properties of aerosols.
