Integrated Assessment on regional climate and air quality (II)

The long-range transport of regional atmospheric pollutants (eg, acidic contaminants, dust, haze, ozone, etc.) has a significant impact on Taiwan's air quality during certain seasons. Using the scientific methods established in the previous project, the current project continues to examine the impact of transboundary pollution, to carefully evaluate the benefits of air pollution control policies, and to further predict the changes in air pollutants in short- and medium-term as well as the corresponding impacts on air quality in Taiwan. The discussion on the impact of transboundary pollution in Taiwan will focus on analyzing specific events to understand the formation of the episode and the transmission mechanism so as to achieve early precaution measures and provide relevant information to the local authority for contingency plan. This project also continues to explore long-term climate variability, short-term weather patterns and pollutant emissions in East Asia, quantify the background concentrations of atmospheric pollutants in East Asia and Taiwan, and their contributions to transboundary pollution in Taiwan. In addition, the WRF/CMAQ numerical model is also applied to establish a regional atmospheric transport model system to evaluate and predict the impact of local and transboundary atmospheric pollutants in Taiwan. The outcome of the project will further establish the operational methods and tools for air quality forecast and abnormal event diagnosis which can strengthen the ability of emergency response and decision-making. Besides, the project also actively expands and participates in international collaboration and is in line with the current international technology.
