In Air Pollution Issues, emission source is one of the key issues. In addition, atmospheric parameters such as wind, temperature, radiation are also dominant factors on transportation and concentration of pollutants. Consequently, to understand the evolution of local atmospheric environment is very important on the air pollution problems. A 1290 MHz boundary layer wind profiler was built on Kou-Hsiung / Ping-Tung Area, the most series polluted area in Taiwan, by Environmental Protection Agency in 2006. This powerful remote sensing instrument could supply information on evolution of local flow, boundary layer, as well as the ventilation coefficients. These kinds of information are very important and helpful on the air quality monitoring.
Data performance analysis showed the wind profiler operated well and had very good quality during 2006; expect lower humidity (winter season) and instrument damaged condition. According to the high correlation factor (~ -0.8), it indicated the evolution of PM10 concentration and ventilation coefficient have well opposite phase changing tendency. From the less correlation but periodic change between O3 and ventilation coefficient, it showed the thermal parameters should be important and need to be observed. Continuously observation by wind profiler is very necessary in air pollution monitoring and forecasting, new parameters and application can develop by wind profiler and apply in air pollution.
