Abstract

The aim of this study was to investigate the microclimate influence of Alfredo Andersen Square in the city of Curitiba PR. This square is a wooded area, with 24 large-sized trees. Its microclimate influence was analyzed with a promptly meteorological data collection, using two Kestrel®’s mini-stations, model 4,200.The data on temperature, humidity and wind speed, werecollected simultaneously in the center of thesquare and in a mobile transect on Augusto Stellfeld Ave. The transect had approximately 1,000 m, with the meteorological data collected every 50 m. The results showed that, on average, the temperature in the square was 1.4 oC lower than on the avenue, the wind speed was 0.29 m/s lower, and the humidity was 5% higher. Since there are urban trees along Augusto Stellfeld Ave., some data from the mobile transect were collected under those trees, which interfered on the results interpretation. Hence, the influence radius of this square on its surroundings could not be determined, being observed only for 200 m.We concluded that Alfredo Andersen Sq collaborates to improve the urban microclimate in the city of Curitiba.
