             abstract = "Water temperature plays an important role in ecological 
                         functioning and in controlling the biogeochemical processes of a 
                         water body. Conventional water quality monitoring is expensive and 
                         time consuming. It is particularly problematic if the water bodies 
                         to be examined are large. Conventional techniques also bring about 
                         a high probability of undersampling. Conversely, remote sensing is 
                         a powerful tool to assess aquatic systems. The objective of this 
                         study was to map the surface water temperature and improve 
                         understanding of spatiotemporal variations in a hydroelectric 
                         reservoir. In this work, MODIS land-surface temperature (LST) 
                         level 2, 1-km nominal resolution data (MOD11L2, version 5) were 
                         used. All available clear-sky MODIS/Terra images from 2003 to 2008 
                         were used, resulting in a total of 786 daytime and 473 nighttime 
                         images. Descriptive statistics (mean, maximum and minimum) were 
                         computed for the historical images to build a time series of 
                         daytime and nighttime monthly mean temperatures. The thermal 
                         amplitude and anomaly were also computed. In-situ meteorological 
                         variables were used from 2003 to 2008 to help understand the 
                         spatiotemporal variability of the surface water temperature. The 
                         surface energy budget and the depth at which the wind can 
                         distribute the heat input of a given surface were also measured. A 
                         correlation between daytime and nighttime surface water 
                         temperatures and the computed heat fluxes were made. These 
                         relationships and the causes of the water surface temperature 
                         variability are discussed.",
