Abstract
Nitrogen dioxide (NO2) and Nitric Oxide (NO) are two gases that affect air quality. Both are mainly emitted from vehicles. Ozone (O3) is a secondary pollutant that is formed by a series of photochemical reaction that involves NO, NO2 and UV radiation. These gases shows an increase trend in Surabaya, Indonesia. Therefore it is crucial to find out their diurnal pattern and relationship with vehicles. The data used are data from air monitoring station (SUF) 1, 6 and 7 Surabaya from 2012 to 2016. The concentration of air follows a certain pattern following the pattern of the source of the contamination. Daily pattern of NO and NO2 concentrations has 2 peak times in the morning and afternoon. As for the daily pattern of O3 has peak time during the day. Daily patterns may be affected by motor vehicles.
