                         Mission (TRMM) Multi-satellite Precipitation Analysis (named TMPA 
                         and TMPA-RT for the near real-time version) are widely used both 
                         in research and in operational forecasting. However, they will be 
                         discontinued soon. The products from the Integrated 
                         Multi-satellite Retrievals for Global Precipitation Measurement 
                         (IMERG) and The Global Satellite Mapping of Precipitation (GSMaP) 
                         are analyzed as potential replacements for TMPA products. The 
                         objective of this study is to assess whether the IMERG and/or 
                         GSMaP products can properly replace TMPA in several regions with 
                         different precipitation regimes within Brazil. The validation 
                         study was conducted during the period from 1st of April, 2014 to 
                         the 28th of February, 2017 (1065 days), using daily accumulated 
                         rain gauge stations over Brazil. Six regions were considered for 
                         this study: five according to the precipitation regime, plus 
                         another one for the entire Brazilian territory. IMERG-Final, 
                         TMPA-V7 and GSMaP-Gauges were the selected versions of those 
                         algorithms for this validation study, which include a bias 
                         adjustment with monthly (IMERG and TMPA) and daily (GSMaP) gauge 
                         accumulations, because they are widely used in the users 
                         community. Results indicate similar behavior for IMERG and TMPA 
                         products, showing that they overestimate precipitation, while 
                         GSMaP tend to slightly underestimate the amount of rainfall in 
                         most of the analyzed regions. The exception is the northeastern 
                         coast of Brazil, where all products underestimate the daily 
                         rainfall accumulations. For all analyzed regions, GSMaP and IMERG 
                         products present a better performance compared to TMPA products; 
                         therefore, they could be suitable replacements for the TMPA. This 
                         is particularly important for hydrological forecasting in small 
                         river basins, since those products present a finer spatial and 
                         temporal resolution compared with TMPA.",
