Abstract

There are several times where Malaysia suffers from severe air pollution, especially the urban and industrial area. The air quality stations across the country monitor various variables of air pollutants including particulate matter such as PM₁₀. Due to harmful effects of pollution on human health and the environment, especially for extreme cases, air quality is a matter of worldwide concern amongst scientists, policy makers and public alike. In extreme value analysis, the generalized extreme value (GEV) distribution is widely adopted, and its parameters were estimated by various methods. Studies on these estimation methods are of great interest since reliable estimates are needed for modelling and forecasting extreme events. In this study, two methods based on order statistics are compared which are the L-moments (LMOM) and maximum product spacing (MPS) method. The L-moments method is a common method in extreme value analysis while MPS is considered as an alternative for maximum likelihood estimation (MLE) method. Both methods are applied on daily maximums of PM₁₀ concentration at eight air quality monitoring stations in Peninsular Malaysia. Both methods provide a relatively close estimates and MPS is shown to be a reasonable alternative for parameter estimation of GEV distribution of extreme PM₁₀ concentration in Malaysia.
