Abstract

Atmospheric turbidity parameters over Manila were obtained using a sunphotometer. The values of AOD range from 0.159 (675 nm) to 0.800 (368 nm) while β and α varied from 0.113 to 0.325 and 0.04 to 1.185, respectively. The monthly variation of β showed that the month of May contained the least amount of aerosols. It was observed that the prevailing value of AOD is around 0.300 to 0.500 while β was predominantly valued from 0.150 to 0.250, with both distributions having the same shape. The behavior of the turbidity parameters, α and β, varies from day to day. Some have similar or opposite diurnal trends, while others have a mixture of the two. This was probably due to the different processes that occur in the atmosphere.
