Change in albedo and land surface temperature after artificial beach fattening of Praia Central in Balneário Camboriú/SC, Brazil

Abstract

This research concerns in to measure the alteration of surface albedo and Land Surface Temperature (LST) of Praia Central of Balneário Camboriú/SC, Brazil, after artificial beach fattening occurred in 2021. Landsat 8 OLI sensor was used to create albedo maps and the TIRS sensor for the LST. Adopting the absence of clouds as a criterion for the analysis, the images were downloaded from the United Service Geological Survey (USGS) website. These images were processed in the QGIS software, generating the surface albedo and LST data. An increase of 150% in the average surface albedo and 15% in the average LST in extended are of the Praia Central was sensitively observed. This positive variation shows a spectral change in the surface of the shore, whose thermal variations can negatively impact thermal comfort along the waterfront area of Balneário Camboriú. For future perspectives, the importance of microclimatic studies associated with artificial beach fattening in urban regions becomes evident.
