Análise do Comportamento da Temperatura de Superfície e Fluxo de Calor no Solo: um Estudo de Caso no Perímetro Urbano de Montes Claros, Minas Gerais / Analysis of the Behavior of Surface Temperature and Heat Flow in Soil: a Case Study in the Urban Area...

Abstract

The goal of this work is to use remote sensing methods to understand the behavior of soil heat flux and surface temperature in different urban land uses in Montes Claros. This municipality was chosen for study because the city has experienced rapid population growth which has increased demand for housing and industrialized food supplies. The results presented in the research are shown to be relevant for other studies treating urban land use dynamics related to energy balance variables. The heat flux in the soil had the lowest values for areas with well defined vegetation cover, both Cerrado and Tropical Rainforest, and the opposite was observed in areas of anthropic action. However, the highest value of heat flow in the soil occurred in water, justified by the amount of energy used to heat water mass and by the analyzed literature. The thermal averages analyzed here followed the flux of soil heat flux in relation to native vegetation areas, with lower values and higher values observed for anthropogenic areas within the urban zone of Montes Claros.
