The overestimation of extreme precipitation over
tropical Pacific islands is noteworthy. On the other hand,
it is also likely that APHRODITE underestimates precipitation
because of limited gauge number and grid
average.
Low estimates, especially for extreme precipitation,
are likely to occur when the grids have fewer
than two gauge stations (P. Xie 2014, personal communication).
These results emphasize the utility of converting
different datasets in ARI
