                         ABSTRACT: The spatial variability of rainfall from 1981 to 2016 
                         was analyzed in the Negro river basin. Precipitation estimation 
                         data from the CHIRPS v.2 project with spatial resolution of 0.05 
                         degrees were used. The results indicated a high spatial contrast 
                         of precipitation over the drainage areas of the rivers Negro and 
                         Branco. It was identified a greater influence of the relief on 
                         precipitation climatology in the drainage area next to the Guiana 
                         shields, mainly in the tributaries of the upper Branco river and 
                         in the region of formation of the Negro river (Casiquiare 
                         channel). A low spatial variability was observed between the 
                         maximum and minimum precipitation ratio in the 25 sub-basins 
                         evaluated. The data used are useful for climatic studies of poorly 
                         monitored regions in the Amazon basin.",
