             abstract = "In recent years there has been a continuous advance of the 
                         agricultural frontier of oil palm in the Amazon region, which 
                         causes changes in soil cover in this region. Given the need to 
                         understand the influence of this crop on surface albedo, the 
                         present study aims to compare the fluctuations of surface albedo 
                         in oil palm culture area with those of pasture, forest and 
                         secondary vegetation. To make this comparison, orbital data based 
                         on Terra / MODIS satellite product MCD43A3 for the years 2015 and 
                         2016 were used. The samples selected for the study area showed 
                         that the oil palm showed little variation, estimating values 
                         medium \α = 0.14, being statistically distinct from other 
                         uses and coverings, with the albedo: Pasture > Palm Oil > 
                         Secondary Vegetation > Forest. Demonstrating that possible 
                         conversions from one cover to another can influence the surface 
                         radiation balance, ie if oil palm cultivation continues to advance 
                         over pasture areas, this would decrease surface albedo and 
                         consequently have microclimate changes, however. If expansion 
                         occurs over areas of Secondary Vegetation or Forest an inversion 
                         will occur and may contribute to climate change. RESUMO: Nos 
                         {\'u}ltimos anos tem-se verificado um cont{\'{\i}}nuo 
                         avan{\c{c}}o da fronteira agr{\'{\i}}cola da palma de {\'o}leo 
                         na regi{\~a}o amaz{\^o}nica, o que provoca 
                         altera{\c{c}}{\~o}es na cobertura do solo nessa regi{\~a}o. 
                         Diante da necessidade de se compreender a influ{\^e}ncia deste 
                         cultivo no albedo de superf{\'{\i}}cie, o presente estudo visa 
                         comparar as flutua{\c{c}}{\~o}es do albedo de 
                         superf{\'{\i}}cie em {\'a}rea de cultura de palma de {\'o}leo 
                         com os de pastagem, floresta e de vegeta{\c{c}}{\~a}o 
                         secund{\'a}ria. Para fazer esta compara{\c{c}}{\~a}o foi 
                         utilizado dados orbitais, com base no produto MCD43A3 do 
                         sat{\'e}lite Terra/MODIS para os anos de 2015 e 2016. As amostras 
                         selecionadas para {\'a}rea de estudo mostrou que a palma de 
                         {\'o}leo obteve pouca varia{\c{c}}{\~a}o, estimando valores 
                         m{\'e}dios \α = 0.14, sendo estatisticamente distinto dos 
                         outros usos e coberturas, com o albedo: Pastagem > Palma de 
                         {\'O}leo > Vegeta{\c{c}}{\~a}o Secund{\'a}ria > Floresta. 
                         Demonstrando que poss{\'{\i}}veis convers{\~o}es de uma 
                         cobertura para outra podem influenciar no balan{\c{c}}o de 
                         radia{\c{c}}{\~a}o na superf{\'{\i}}cie, ou seja, caso o 
                         cultivo da palma de {\'o}leo continue avan{\c{c}}ando sobre as 
                         {\'a}reas de pastagem, isto diminuiria o albedo de 
                         superf{\'{\i}}cie e consequentemente teria mudan{\c{c}}as no 
                         microclima, todavia, se a expans{\~a}o ocorrer sobre {\'a}reas 
                         de Vegeta{\c{c}}{\~a}o Secund{\'a}ria ou Floresta ocorrer{\'a} 
                         uma invers{\~a}o, e poder{\'a} contribuir para 
                         altera{\c{c}}{\~o}es clim{\'a}ticas.",
