Rainfall varies in intensity and depth over time and space. Weather radar systems can provide estimates of rainfall at points in space with nearly continuous coverage with respect to time. A study was conducted to investigate the effects, on hydrologic forecasts, of varying the resolution of radar rainfall estimates in both time and space. A definite relationship was found to exist between the standard error of the hydrograph peaks and the radar grid spacing as well as the time interval between measurements.
