Uncertainties in Precipitation and Their Impacts on Runoff Estimates

This is the authors' abstract. We don't add key points for this paper.

Water balance calculations are becoming increasingly important for earth-system studies. Precipitation is one of the most critical input variables for such calculations because it is the immediate source of water for the land surface hydrological budget. Numerous precipitation datasets have been developed in the last two decades, but these datasets often show marked differences in their spatial and temporal distribution of this key hydrological variable.
