Seminar on Potential Sources of Particulate Matter using Source Tagging Modelling. The seminar will discuss alternative methods to quantify emission source contribution using both monitoring and chemical transport models during the haze and non-haze periods. This seminar supports by Asia Pacific Network (APN)’s Project under Collaborative Research for Early-Career Scientists (CRECS) Small Grants Programme, and collaboration between USM, UKM, and Itenas.
