In order to study the characteristics of ozone pollution dynamics in tropical island cities and their relationship with meteorological factors, the authors processed daily and hourly air quality automatic monitoring data and meteorological observations in Haikou City from 2016 to 2020. The dataset of ozone pollution characteristics and impact factors (2016-2020) was developed. The data results show that the peak ozone concentration period of Haikou City is mainly in the autumn and winter seasons from October to December. The diurnal variation presents an obvious single-peak feature, with a valley at 8:00 and a peak at 14:00-16:00. O3 concentration is positively correlated with CO concentration and wind speed, negatively correlated with humidity. The dataset includes: (1) geo-location of the sites; (2) monthly concentration data of O3, CO and NO2 in Haikou from 2016 to 2020; (3) monthly and annual O3 concentration at four monitoring sites from 2016 to 2020; (4) daily variation data of O3 concentration at four monitoring sites from 2016 to 2020; (5) O3 concentration, air pressure, air temperature, humidity and wind speed data at four monitoring sites. The dataset is archived in .shp and .xlsx data formats, it consists of 9 data files with data size of 33 KB (Compressed into one file with 29.3 KB).
