Borneo Science Journal, 8, 62-72.https://repoemc.ukm.my/handle/123456789/712Air dispersion models have been widely used to address air quality problems at microscale in urban environments, as they are capable of providing valuable information for better and more efficient urban air quality planning. The aim of this paper was to measure the CO concentration near roadways and intersections at three major roads in Kota Kinabalu city centre during morning, afternoon and evening peak hours using CAL3QHC dispersion model and also to identify CO concentration;hot-spots'.Carbon monoxideCAL3QHC dispersion modelintersections,modellingmotor vehiclesreceptorsJournal
