[PDF][PDF] Night-time ground-level ozone trends and variability over the urban sites
S Shith, NA Ramli - Journal of sustainability science and …, 2019 - jssm.umt.edu.my
This study evaluates the variation of night-time ground-level ozone (O3), nitrogen dioxide
(NO2) and nitric oxide (NO) from year 2015 to 2016. During this period, the recorded
maximum night-time ground-level O3 was 55 ppb at Putrajaya (PT), which have more areas
with higher brightness level compared to another urban site, Alor Setar (AS) at 21 ppb.
Lower NO concentrations restricted the sinking agents, thus, reducing the depletion rates
and resulted in O3 to remain in the atmosphere. The contributor toward night-time ground …

This study evaluates the variation of night-time ground-level ozone (O₃), nitrogen dioxide
(NO₂) and nitric oxide (NO) from year 2015 to 2016. During this period, the recorded
