The spatial and temporal variability of air pollutants in an urban area is great. Superimposed on daily meteorological variability are seasonal cycles of human activities that influence air quality. The objective of this research was to analyze the spatial and temporal variation of polluting gases: sulfur dioxide, nitrogen dioxide and ozone in two locations in Havana from November 2015 to October 2016. Hourly concentration data from two Automatic Atmospheric Monitoring Stations. The statistical processing of the data was carried out using the MS-Excel and Origin 2016 software. The non-pa rametric Mann-Whitney U, Kruskal-Wallis H, and Dunn tests were applied. In general, the concentrations of the pollutants corresponded to the distribution patterns characteristic of urban locations.

Palavras-chave : sulfur dioxide; nitrogen dioxide; ozone.
