Abstract

Abstract Spatiotemporal variations of tropospheric ozone concentrations in the Warsaw Agglomeration (Poland). The study uses ozone concentrations from stations in Warsaw Agglomeration and its vicinity. Diversity of localizations of considered station, in terms of type of emissivity, allows on comparison of air pollution conditions by ozone in Warsaw area. Concentration of ozone in summer and spring were above twice greater than the concentration in autumn and winter. The greatest differences between weekend days concentration and work days concentration occur during autumn and winter, but in the same time the differences during the day are the least, especially in urban site stations. Statistics analysis shows strong relationship between ozone concentration and nitrogen dioxide concentration and meteorological elements especially for days with high level of ozone concentration. For these days regression equations were statistically significant (α = 1%) and correlation coefficients were greater than 0.81. Polynomial of IV power is the best fitted function of one-hourly values of ozone concentration course in particular seasons.
