Balanço de Energia no perímetro urbano de Campos dos Goytacazes, RJ: Um estudo de caso

Abstract

According to the UN, the urbanization trend is growing, with a global growth projected in absolute terms reaching 665 in 2050. Using orbital digital images and remote sensing techniques, this work aimed to evaluate the behavior of the energy balance of the city of Campos dos Goytacazes, RJ contextualizing water stress and correlating it with surface temperature. It was observed that the urbanized land compared to the non-built-up area presented the highest fluxes of sensible heat and heat in the soil. In urban areas, the lowest values of radiation balance and latent heat flux were found, generating higher temperatures in the urban soil, and vegetated areas presented a greater latent heat flux and lower soil heat flux. There was also a correlation of 96% between water stress and temperature, strongly influencing energy flows, or for changes in the energy balance of the environment, further analyzes are proposed in different water conditions to compare with the results obtained with this work.
