Hello!
It's Kim Joo today :) I'll touch on how Singapore monitors her ambient(surrounding) air quality.

Our ever-wonderful NEA monitors our air quality by using the Telemetric Air Quality Monitoring and Management System (TAQMMS). Sounds like a complex thing, huh? Basically, the system comprises of remote air monitoring stations that are linked to a Central Control System (CCS) via dial-up telephone lines, and provides an efficient means of obtaining air quality data.

These stations are also equipped with continuous automatic analysers to measure concentration for :

Sulphur Dioxide

Ozone

Carbon Monoxide

Oxides of Nitrogen

Particulate of matter

Out of these 16 stations, 13 are used to monitor ambient air quality while the remaining 3 monitors roadside air quality.



The ambient stations are classified as

urban,

industrial

and sub-urban stations
depending on the activities in the area where they are located. The 3 roadside stations are located near busy roads or expressway and are used to assess the adequacy and effectiveness of NEA’s vehicular emission programme.

The data will be automatically processed at the CCS to give an update on air quality, with immediate access to air quality data collected at the monitoring stations. It also provides numerical models for simulation of various air pollution scenarios.

And this, is how Singapore monitors her ambient air quality. :)

Be good kids!
Save the Earth!
