Calibração e validação do Single Layer Urban Canopy Model (SLUCM) para a cidade de Manaus

Abstract

The global urban expansion has been accelerating in the last decades and has contribute to the exchange of natural environment, where the anthropic action is observed as a main agent of this phenomenon. Within the current scenario of climate change and the need for specific information about the urban climate, and in conjunction with the dynamic and spatial structures related to the complex geometry of cities, methods were tested to calibrate and validate the Single Layer Urban Canopy Model (SLUCM) for Manaus (AM). Micrometeorological sensors were installed for the urban monitoring at various height levels in two micrometeorological tower with 12 and 30 meters height to perform numerous numerical simulations, with the purpose of adjusting the thermal, radiative and dimensional parameters of the urban cover. In general, the model achieved a satisfactory performance in the results obtained after technical adjustments conditioned to the study region, but some of the estimates did not perform well due to systematic and unsystematic errors that depend on improvements of physical parameterizations and inclusion of processes in the model. Finally, the general understanding of the expansion processes effects in a densely urbanized area in Manaus served as a basis for adjusting SLUCM model parameters related to the urban canopy, which will be able to provide a more accurate tool for environmental impact studies in urban centers.
