The goals of this study are (1) to establish an integrated atmospheric modeling system for studying the long-range transport of regional air pollutants in order to predict and assess their impact on Taiwan air quality, and further to provide fundamental information to the EPA and local EPB for air pollution management, (2) to revise the PSI when abnormal air pollution events occur, (3) to plan and establish a new acid deposition net work for conducting a long-term monitoring and data analysis, (4) to develop a localized critical loading of acid deposition for assessing the buffering capacity of the soil in Taiwan, (5) to update and maintain the web site of acid rain study in Taiwan, and (6) to promote regional international collaborations.
To date, our achievements are highlighted below:
The modeling system has integrated the meteorological data from CWB and NCEP, and subsequently performed daily simulations. Predicted trajectories originated from the major source points of air pollutants in East Asia have been provided on the website for precaution of the long-range transport. Meanwhile, backward trajectories starting at four locations of Taiwan are also provided for tracking the potential source regions.
Based on a statistic model, the PSI during the abnormal event of the year of 2003 has been recalculated in consideration of Asian dust impact on PM10 measurements
A new acid rain monitoring network consisting of 12 sites has been set up since January 2003 for a long-term measurement of dry and wet deposition.
The web site (http://www.acidrain.org.tw) of Taiwan acid rain study has been updated with more information.
The Experts Workshop on Acid Deposition in East Asia was held in Taipei on 15-17 November 2003. Experts from Japan, Hong Kong, USA, China, and Taiwan agreed to establish a Pacific Rim region network for information sharing and exchange of acid deposition data. Our network is also extended to collaborate with EANET, NADP and CAD.
