 We conducted a comprehensive evaluation of 22 grid, quasi, global, sub, daily precipitation data sets for the period 2000 to 2016. 13 non-gauge corrected P data sets were evaluated using daily P gauge observations from 76,086 gauges worldwide. Additionally, we evaluated 9 gauge corrected data sets using hydrological modeling by calibrating the HPV conceptual model against stream flow records for each of 9,053 small to medium-sized, less than 50,000 square kilometers, catchments worldwide. Finally, marked differences in spatiotemporal patterns and accuracy were found among the data sets. Among the uncorrected P data sets, the satellite and reanalysis-based MSWEPing version 1.2 and version 2.0 data sets generally showed the best temporal correlations with the gauge observations, followed by the reanalysis, ERA interim, JRA 55, NCEP-CFSR, and the satellite and reanalysis-based CHIRP version 2.0 data set, the estimates based primarily on passive microwave remote sends.
