Surface Temperature and NDVI Behavior Analysis in September in Manaus/AM City

Abstract

The city of Manaus has been going through a process of accelerated and disorganized urban growth, which causes situations that characterize many challenges and environmental problems. Among these, we highlight the change in the local climate, causing the so-called Urban Heat Island (UHI) that arises in the area of the metropolitan region and is characterized by the rise in surface temperature when compared to the predominant temperature in the regions of urban sites. This phenomenon relates to anthropic activities on the surface and its consequence in the lower troposphere, which results in the increase in average temperatures and the number of hot days, intensifying thermal discomfort in the population. Thus, the objective of this work is to analyze the evolution of the heat island in the geographic space of the city of Manaus in the last 10 years, using remote sensing data, to estimate the values of surface terrestrial temperature, using Thermal maps generated from composites of AQUA satellite images, MODIS sensor: Surface Temperature and NDVI from THE LPDAAC (Land Processes Distributed Active Archive Center, NASA. Based on the data and analyses performed, it was possible to see an increase in temperature with a temporal variation in the years 2010 to 2019 as well as the expansion of warmer spaces, which invigorates the influence of UHI in the amazonense metropolis.
