摘要：
This study aims to map the urban heat island in the metropolitan area of Rio de Janeiro (MARJ) using remote sensing data to derive land use maps and land-surface temperature (LST) fields based on Landsat data. The LST difference between urban and vegetation and the temporal evolution of LST were verified based on the Students's t statistical test conducted at the 5% level. Obtained results indicate that LST has increased by approximately 2.0 degrees C over the last decade and that urban heat island has increased from 4.4 to 6.1 degrees C.
