Effect of Prevailing Winds on Pollution Patterns in Lingayen

By: M. A. Estoque and R. T. F. Balmori

The dependence of pollution patterns in the coastal waters of Lingayen Gulf on the prevailing winds is studied with the aid of a theoretical model. The model equations consist of the well-known vertically integrated hydro-dynamical equations and a mass transport-dispersion...

Ambient SO2 Monitoring using Differential Optical Absorption Spectroscopy (DOAS)

By: R. N. Choy, C. K. G. Castillo, S. Y. Uy and J. T. Villarin

A prototype DOAS instrument was assembled to measure ambient concentration of Sulfur Dioxide (SO2). A folded-path configuration employing retroreflectors was chosen because of advantages in sensitivity and convenience in housing the transmitter and receiver together. The measurement path length...

Diurnal variations of NO2 concentrations at the Manila Observatory, Quezon City

By: A. R. C. Remedio, R. T. F. Balmori and M. A. Estoque

A combined observational and theoretical study of diurnal variations of NO2 concentrations of the air at the Manila Observatory (Quezon City, Philippines) in June and August 2002 was made. The concentrations were monitored using a Differential Optical Absorption Spectroscope (DOAS).
