Investigating the Urban Heat Island Effect in Salta, Argentina: The Influence of Traffic Volume and Wind Speed on Surface Temperature

This investigation examines the extent to which the city of Salta, Argentina, exhibits the urban heat island (UHI) effect, specifically analyzing the impact of traffic volume and wind speed on surface temperature.

The student employed a linear transect sampling method, utilizing infrared thermometers, digital anemometers, and manual traffic counts. Data was analyzed using choropleth maps and the Pearson correlation coefficient to determine statistical relationships.

Findings indicate a moderate positive correlation between traffic and temperature (r = 0.39) and a moderate negative correlation with wind speed (r = -0.36). The study concludes that the UHI effect is not fully present, as peak temperatures occurred on peripheral avenues rather than the city center.
