A normalized norm between the time series of radar and gauge rain rates is defined as a measure of agreement between them. The calibration constant of a radar for rain measurements is determined to be the value which minimizes the normalized norm between the radar and gauge rain rates. The results of the experiment show the rain-to-rain variation of the calibration constant. The variation can be partly explained as due to the variation of raindrop size distribution.
