Mass extinction efficiency of aerosols measured during the 2006 New Year celebration in Manila
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.
