Techniques & Development
Long-range transport (LRT) of PM2.5 in East Asia From the analysis of Taipei supersite observation, we found the impact of PM2.5 from Asian continent was huge (Lee et al., 2006). Then we started applied the CMAQ model to simulate the haze plume transporting from Shanghai to Taipei (Chuang et al., 2008b). The evolution of precursors and PM2.5 compositions is a very interesting issue. Later, we hold another a simulation study which showed the different characteristics of severe LRT, mix of LRT and local pollution (LP), and pure LP (Chuang et al., 2017).
To answer the proportion of LRT and LP in Taiwan. We developed an economic method to quantify the contribution of LRT and LP in western cities of Taiwan under prevailing northeast wind from 2006 to 2015 (Chuang et al., 2018). Recently, we applied the process analysis technique of CMAQ to study the transport mechanism of haze LRT from the three biggest industrial regions to Taiwan (Chuang et al., 2020).
Long-range transport of biomass burning (BB) aerosol from Southeast Asia to Taiwan First, we analyzed the characteristics of PM2.5 water-soluble ions Lee et al., 2011) and carbonaceous content (Chuang et al., 2014)observed at the Lulin Atmospheric Background Site to reveal the impact of BB aerosols from Southeast Asia. Subsequently, we analyzed the aerosol properties at northern Thailand (Chuang et al., 2013a) and DongSha island (Chuang et al., 2013b). With the observations at north Thailand and Lulin site, we studied the aging of BB aerosols during the transport between these two locations. Later, we applied CMAQ to study probe the chemical evolution of precursors and BB aerosols during the transport (Chuang et al., 2015). Meanwhile, we displayed the chemical evolution of BB aerosols after the plume moved near Taiwan and how the BB aerosols influence western Taiwan on the ground (Chuang et al., 2016).
Air quality forecast I am involved in this research since as a postdoc in NCSU, using the WRF/Chem-MADRID to provide daily real-time forecast over the Southeastern United States (Chuang et al., 2011). After coming back to Taiwan, we restarted the air quality forecast in NCU since 2016. In RCEC, I participated in the air quality forecast on the evaluation of forecast results. Meanwhile, I have been working on the update and validation of emission inventory.
urban pollution My Ph.D. thesis was a study of aerosol events for the Taipei metropolitan. At that time, we started the study of high PM2.5 weather patterns and the effect of complex terrain on the role of aerosol events (Chuang et al., 2008a). Subsequently, we applied CMAQ to simulate the haze LRT from Asian continent to Taipei (Chuang et al., 2008b). In 2015, we applied the PMF model to find out the sources and their contribution in PM2.5 event in Taoyuan city (Chuang et al., 2016). After joining the RCEC, we will start the Ozone and PM2.5 study in Taichung metropolitan.
