Introduction of singapore's gas emission
Measures taken by NEA
NEA monitors the ambient air quality through the Telemetric Air Quality Monitoring and Management System. The system comprises remote air monitoring stations linked to a Central Control System via dial-up telephone lines, provides an efficient means of obtaining air quality data.The monitoring stations monitor both ambient and roadside air quality. The automatic analysers and equipment at the stations measure the concentrations of major pollutants such as sulphur dioxide, oxides of nitrogen, carbon monoxide, ozone, hydrocarbons and respirable suspended particles (PM10).

New policy adopted by NEA
The present project aims at developing a state-of-the-art three dimensional, non-hydrostatic mesoscale computer model for air pollutant dispersion and transport analysis. The model will cover a wider range of problems typical for tropical air dispersion conditions in Singapore. The computational air dispersion model will include complicated physics of flow, mass, momentum, energy transport and chemical transformation over a large computational domain. Fundamental physical understanding, meaningful air quality prediction and reliable parameter estimations will be verified with the air quality and meteorology data available from the National Environment Agency (NEA). Advanced computational technologies, such as high accuracy algorithm, parallel processing will be employed in the model, to achieve high computational efficiency. The developed air pollutant dispersion model will enhance NEA's capability in real time air quality analysis, environmental evaluation, management planning, emergence response, and policy making support.
