             abstract = "Understanding precipitation systems and their impacts is crucial 
                         for predicting extreme rainfall events and mitigating their 
                         adverse effects. The South American Monsoon System (SAMS) 
                         regulates rainfall across the continent and is related to the 
                         Intertropical Convergence Zone (ITCZ) and the South Atlantic 
                         Convergence Zone (SACZ). Using a complex network approach, we 
                         analyzed rainfall and extreme rainfall events by satellite 
                         estimation in South America and the Amazon basin during the summer 
                         season. The goal was to identify highly connected regions or 
                         communities based on the daily IMERG (Integrated Multi-satellitE 
                         Retrievals for GPM) data and gain insights into precipitation 
                         dynamics. Comparing these communities allowed us to understand 
                         variations and sensitivities within the regions, as well as verify 
                         the sensitivity of the technique. The findings indicated that the 
                         extreme rainfall networks in South America and the Amazon basin 
                         show a similar spatial distribution of communities. These 
                         communities are primarily influenced by the transport of low-level 
                         moisture from the eastern Amazon towards the Andes, eventually 
                         exiting the Amazon basin towards the extratropics. The central 
                         region of the Amazon basin serves as a moisture source, while the 
                         southeast region acts as a moisture sink. In the case of the 
                         satellite rainfall networks in the Amazon basin, three important 
                         regions were identified: northwest, northeast, and southeast. The 
                         first two regions are associated with the inflow of moisture into 
                         the basin, while the third region is linked to the outflow. The 
                         identification of the communities revealed a spatial distribution 
                         that is associated with the predominant flow during the SAMS, 
                         highlighting the significant role of the Andes in this dynamic. 
                         Finally, communities offer valuable information that can be 
                         utilized in various ways, such as the development of specialized 
                         models for specific regions, which can lead to improved 
                         forecasting results.",
