Instrumentação, modelagem e validação de procedimento a partir de gradientes de temperatura e umidade relativa

Abstract

The relationship between city and nature is increasingly problematic due to the expansion of urban areas without plans that are created contradictions between social and environmental issues and the political and economic interests. One way to mitigate the environmental impacts of intensive human intervention on the natural environment is the implementation and preservation of green areas, aiming at improving the quality of life. These places should be public and managed to fulfill their real role. Among the different types of green areas can be highlighted the Urban Parks. The general objective of this research is to develop and validate procedure for estimating UTCI from gradients of temperature and relative humidity. The index used for the analysis of thermal comfort was the UTCI - Universal Thermal Climate Index. The UTCI is among the latest thermal comfort indexes, it was developed in Europe and it has been widely adopted in assessments relating to thermal comfort in outdoor environments. With datalogger, transect was made in the most frequented the Park trails. The collected data was subjected to analysis semivariogram, kriging and preparation of UTCI map of the Park of two seasons, dry and rainy, morning and evening period, identifying the thermal stress according to the table of UTCI. The characterization by UTCI index of the Park allowed identifying in which classes of thermal stress are users subjected in different types of floorings and vegetation in the microclimate conditions in Cuiaba, Brazil. It will provide the Park users to know the most suitable places for the practice of various types of activities in this important recreational area within the city, for this we developed a Logger for relative georeferenced collection of temperature and relative humidity and geostatistical analysis of the data collected, and it was found the park is covered by the thermal discomfort heat as UTCI table.
