Effect of Monsoonal Period toward Night-time Ground Level Ozone in East Coast Malaysia. In IOP Conference Series: Earth and Environmental Science (Vol. 549, No. 1, p. 012003). IOP Publishing.https://repoemc.ukm.my/handle/123456789/479This study aims to identify the effect of monsoonal period toward nighttime ground level ozone in East Coast Malaysia depending on different land use area which is industrial and urban areas. The concentration of O3, NO, NO2 temperature (T), relative humidity (RH) and wind speed (WS) were used and collected from Air Quality Division of the Department of Environment, Malaysia. The data proceeded in descriptive analysis and statistical analysis. Temperature, relative humidity and wind speed parameters (symbol of East Coast Monsoonal period), was compared with O3, NO and NO2 concentration with Pearson correlation analysis.enJournal
