Resumo	(*)(?)	A very important physical parameter of a lake or reservoir is its surface temperature. Among other uses, it is a fundamental parameter to calculate the surface energy flux that controls the water temperature and vertical and horizontal stratifications. One way of obtaining the surface temperature is to install in the water body a floating platform collecting this data (among other ones). A severe limitation of such approach is that the data is a point data, and normally one is not sure about its validity for other regions of the lake. To fill this data gap a good option is to use satellite thermal infrared data images. The limitation in this case is the coarse spatial resolution. In this paper we explore the possibility of using remote sensing thermal data of the MODIS and LANDSAT 8 together with an in situ data for the Furnas hydroelectric reservoir in Brazil. The MODIS data due to its 1km resolution was mostly used to assess the temporal variability of the surface lake temperature; due to its good quality control, it was also used as a control to the LANDSAT 8 temperature. The Landsat 8 thermal data at a resolution of 100m was used to assess the spatial variability of the surface temperature field.
