Abstract
A total of 6 months of rainfall data sampled with nine rain gauges on a 500 x 500 meter area has been analysed in order to determine the variability of rainfall within such a small area. The area corresponds to that of a maximum pixel size of a Local Area Weather Radar (LAWR). To calibrate a LAWR, the rain depth from a number of events is used and the analysis is therefore carried out on a total of 29 events fulfilling certain criteria's. The variability is expressed with the coefficient of variation and found to vary from 3 % to 100 % depending on type of rainfall. This gives an uncertainty in that range if a post event specific calibration is performed with a single rain gauge.
