             abstract = "Several studies show the effects of lake breezes on cloudiness 
                         over natural lakes and large rivers, but only few contain 
                         information regarding large flooded areas of hydroelectric dams. 
                         Most Brazilian hydropower plants have large water reservoirs that 
                         may induce significant changes in the local environment. In this 
                         work, we describe the prevailing breeze mechanism in a Brazilian 
                         tropical hydropower reservoir to assess its impacts on local 
                         cloudiness and incoming surface solar irradiation. GOES-16 visible 
                         imagery, ISCCP database products, and ground measurement sites 
                         operated by INMET and LABREN/INPE provided data for the 
                         statistical analysis. We evaluate the cloudiness frequency 
                         assuming two distinct perspectives: spatial distribution by 
                         comparing cloudiness over the water surface and areas nearby its 
                         shores, and time analysis by comparing cloudiness prior and after 
                         reservoir completion. We also evaluated the solar irradiance 
                         enhancement over the water surface compared to the border and land 
                         areas surrounding the hydropower reservoir. The results pointed 
                         out daily average cloudiness increases moving away from the 
                         reservoir in any of the four cardinal directions. When looking at 
                         the afternoon-only cloudiness (14 h to 16 h local time), 4% fewer 
                         clouds were observed over the flooded area during summer (DJF). 
                         This difference reaches 8% during autumn (MAM) and spring (SON). 
                         Consequently, the irradiance enhancement at the water surface 
                         compared to external areas was around 1.75% for daily average and 
                         4.59% for the afternoon-only average. Our results suggest that 
                         floating solar PV power plants in hydropower reservoirs can be an 
                         excellent option to integrate both renewable energy resources into 
                         a hybrid power generation due to the high solar irradiance in 
                         Brazilian territory combined with the prevailing breeze mechanism 
                         in large tropical water reservoirs.",
