URBAN AIR QUALITY MONITORING DEVELOPMENT IN BANDUNG , INDONESIA
Waluyo Eko Cahyono Jr., AER, Bandung, Indonesia
Abstract
Bandung is the third largest city in Indonesia and was one of most polluted cities in Indonesia as its highly developed industries and high density of population. The automatic air quality monitoring system has been developed since 1998. 5 monitoring stations, which including 13 national level stations, has been build by 2003. PM 10, NO2 and SO2 are continuously monitored and the results are published to public through TV, radio and newspaper. O3 and CO are monitored in some stations too and falling dust monitored monthly in more than 20 sites. Air quality monitoring network has taken an important place and provides technical support for air quality management and decision making. Many years monitoring shows that dust and smoke pollution is major problem. PM 10 has not met the national standard in most time of year, which effected by many reasons such as industrial emission, urban construction and sandstorms .SO2 is in heavy pollution status in heating season as coal is still main energy source in the city. NO2 can meet the national standard at present, but the concentration is keeping growth as automobiles increasing sharply in the city. Blue Sky Action has been started since 2001, and many measures have been adopted to control dust and SO2 pollution. In addition the air quality models applied in this study were TAQM (Taiwan Air Quality Model, originated from SARMAP Air Quality Model) and its tracer version. Three domains of different size were designed to illustrate the different distances from the boundaries to interested site. The prevailing wind of the simulated episode was northeasterly and was simulated by MM5. Influences of IC and BC were estimated by the difference between the base case and perturbed runs. Arrival times of tracer were estimated by tracer runs and then compared to those of O3 and CO in runs with full chemistry. Depending on the domain size and distance of the boundary to the site or area of interest, the arrival time and influence of BC are different.
