Abstract
Ozone (O3) is unique among pollutants because it is not emitted directly into the air, and its results from complex chemical reactions in the atmosphere. O3 can bring different effects for all the living on earth (either harm or protect), depending on where O3 resides. This is the main reason why O3 is such a serious environmental problem that is difficult to control and predict. The objective of this paper is to analyze the variations of total column O3 measured by Brewer O3 spectrophotometer over Global Atmosphere Watch Station (GAW) regional station, which is located at southwest of Peninsular Malaysia, Petaling Jaya. Total column O3 observations in Petaling Jaya are studied for the period January 2008 to December 2008. Ozone shows seasonal variation with maximum (276.8 DU in May 2008) during pre-monsoon season and minimum (246.8 DU in January 2008) during northeast monsoon season. In addition, the monthly O3 maps for the year of 2008 were obtained from the NASA-operated Giovanni portal to overview the distribution of total column O3 in Peninsular Malaysia. For the upcoming studies, validation of ground measurements with satellite O3 data and study of tropospheric O3 over the study area is recommended.
