Data of PM10 in selected cities in Malaysia were used to study the performance of parameter estimator of the two-parameter and three-parameter gamma distribution in modeling and predicting PM10 data. This study have considered the method of moment and method of simple explicit to estimate the parameters for the two-parameter and three-parameter gamma distribution respectively. Five performance indicators are used to determine the most appropriate probability distribution for this set of data. Results show that the three-parameter gamma distribution give a better prediction compared to the two-parameter gamma distribution for Nilai, Negeri Sembilan site while the two-parameter gamma distribution predicts the PM10 better compared to the three-parameter gamma distribution for Seberang Perai, Penang site.
