  abstract = {{A} dense rain-gauge network within continental {E}cuador was used to evaluate the quality of various products of rainfall data over the {P}acific slope and coast of {E}cuador ({EPSC}). {A} cokriging interpolation method is applied to the rain-gauge data yielding a gridded product at 5-km resolution covering the period 1965-2015. {T}his product is compared with the {G}lobal {P}recipitation {C}limatology {C}entre ({GPCC}) dataset, the {C}limatic {R}esearch {U}nit-{U}niversity of {E}ast {A}nglia ({CRU}) dataset, the {T}ropical {R}ainfall {M}easuring {M}ission ({TRMM}/{TMPA} 3{B}43 {V}ersion 7) dataset and the {ERA}-{I}nterim {R}eanalysis. {T}he analysis reveals that {TRMM} data show the most realistic features. {T}he relative bias index ({R}bias) indicates that {TRMM} data is closer to the observations, mainly over lowlands (mean {R}bias of 7%) but have more limitations in reproducing the rainfall variability over the {A}ndes (mean {R}bias of -28%). {T}he average {RMSE} and {R}bias of 68.7 and -2.8% of {TRMM} are comparable with the {GPCC} (69.8 and 5.7%) and {CRU} (102.3 and -2.3%) products. {T}his study also focuses on the rainfall inter-annual variability over the study region which experiences floods that have caused high economic losses during extreme {E}l {N}ino events. {F}inally, our analysis evaluates the ability of {TRMM} data to reproduce rainfall events during {E}l {N}ino years over the study area and the large basins of {E}smeraldas and {G}uayas rivers. {T}he results show that {TRMM} estimates report reasonable levels of heavy rainfall detection (for the extreme 1998 {E}l {N}ino event) over the {EPSC} and specifically towards the center-south of the {EPSC} ({G}uayas basin) but present underestimations for the moderate {E}l {N}ino of 2002-2003 event and the weak 2009-2010 event. {G}enerally, the rainfall seasonal features, quantity and long-term climatology patterns are relatively well estimated by {TRMM}.},
