    Fluctuations in nighttime ground-level ozone concentrations during haze events in Malaysia
    (Springer, 2020) Syabiha Shith; Norrimi Rosaida Awang; Mohd Talib Latif; Nor Azam Ramli
    This study focused on O3 variations and the titration effects of NOx during nighttime at urban, industrial, sub-urban and background sites. Nighttime O3 concentration variations and the presence of high particles with an aerodynamic diameter of less than 10 μm (PM10) were examined because haze disturbs the photochemical reactions of O3. Hourly data on O3, NO2, NO and PM10 concentrations provided by the Air Quality Division of the Department of Environment were divided into two groups of daytime and nighttime and analysed.

    Transformational characteristics of ground-level ozone during high particulate events in urban area of Malaysia
    (Springer, 2018) Norrimi Rosaida Awang; Nor Azam Ramli; Syabiha Shith; Nazatul Syadia Zainordin; Hemamalini Manogaran
    Observations of ground-level ozone (O3), nitric oxide (NO), nitrogen dioxide (NO2), particulate matter (PM10) and meteorological parameter (temperature, relative humidity and wind speed) fluctuations during high particulate event (HPE) and non-HPE in Malaysia have been conducted for 2 years (2013 and 2014). The study focuses on urban areas, namely, Shah Alam, Petaling Jaya and Bandaraya Melaka.
