Urban Air Quality


Fine PM Concentrations in Metro Manila (2003)

The UAQ program aims to provide scientific guidance to air quality assessment and mitigation policy development. It seeks to achieve this through monitoring and modeling activities that form the scientific basis of effective air quality management.

The monitoring branch of this program utilizes gas and aerosol sampling technologies to diagnose the present state of urban air quality. The diagnosis is complemented with observations of the urban atmospheric circulation through meteorological monitoring systems.

The modeling branch of the program applies source apportionment, dispersion, and mesoscale modeling systems to deepen our understanding of the sources, transport, and fate of critically important air pollutants in Asian urban centers such as Manila.

Current projects under this program include:
