 We undertook a comprehensive evaluation of 22-grid, quasi, global precipitation, P, datasets for the period 2000 to 2016. 13 non-gauge-corrected P datasets were evaluated using daily P gauge-correcting data from 76086 gauges worldwide. Mark differences in spatiotemporal patterns were found among the datasets. Two of the three re-analyses obtained lower trend errors than the satellite datasets. This article was authored by H. E.
