    Malaysian Borneo has a lower population density and is an area known for its lush rainforests. However, changes in pollutant profiles are expected due to increasing urbanisation and commercial-industrial activities. This study aims to determine the variation of surface O3 concentration recorded at seven selected stations in Malaysian Borneo. Hourly surface O3 data covering the period 2002 to 2013, obtained from the Malaysian Department of Environment (DOE), were analysed using statistical methods.

    The effects of synoptic and local meteorological condition on CO2, CH4, PM10 and PM2.5 at Bachok Marine Research Station (BMRS) in Peninsular Malaysia

    This study is focused on Bachok Marine Research Station (BMRS) which is exposed to different scales of meteorological condition during the northeast (NE) and southwest (SW) monsoons. BMRS experiences both synoptic and land–sea breeze events during the NE monsoon, but only the land-sea breezes are dominant during the SW monsoon. Two case studies were investigated in which the first case study (CS1) was conducted from 25 to 27 January 2016 while the second one (CS2) from 3 to 5 June 2016.

    Particle mass concentrations (PM10, PM2.5 and PM1) and particle number concentration ((PNC); 0.27 μm ≤ Dp ≤ 34.00 μm) were measured in the tropical coastal environment of Bachok, Kelantan on the Malaysian Peninsula bordering the southern edge of the South China Sea. Statistical methods were applied on a three-month hourly data set (9th January to 24th March 2014) to study the influence of north-easterly winds on the patterns of particle mass and PNC size distributions.
