What are the main challenges algorithms have in retrieving rainfall on the central Amazon? Are they able to detect and reproduce the distinct precipitation systems over Amazon? " In order to address these issues, an evaluation of CDRD and GPROF (V04) has been carried out based on groundbased measurements collected during Go Amazon/CHUVA (Machado et al. 2014) Intensive Operation Periods (IOPs - March and September 2014 - wet and dry season, respectively). Analyses of specific case studies over Amazonas is also carried out.
