Analysis of Land Use Influence in Urban Microclimate: Irati-PR Case

The reduction of urban green areas and consequent increase of the built areas is one of the most widely discussed topics nowadays. Both the urban land use dynamics and the climate changes may prove relationships between different uses and land occupations and their consequences for the local microclimate. This paper presents an assessment of the land use influence in the urban climate in a small town. A total of 4 points covering the urban perimeter of Irati, Paraná, with different occupations were selected and temperature and humidity variables obtained with use of adapted hygrometers in thermometric shelter in 4 different times for 4 days. The use of high resolution satellite images enabled the mapping of urban land use in catchment areas within a radius of 350 meters of pre-selected points. The results statistically showed that the use and occupation of land interfere with the climate variables obtained.
