AB: The authors operated two vertically pointing radars collocated at the Iowa City Municipal Airport in Iowa, for eight months. The collected high-resolution data set was analyzed to obtain information about the fractal behavior of rainfall. The two radars are an X-band Doppler radar of The University of Iowa and an S-band Doppler radar of the NOAA Aeronomy Laboratory. The authors applied a power spectrum, wavelet analysis and the box-counting method to investigate the scaling in the rainfall time series. The rainfall time series was extracted from the radar data for three different heights: close to the ground and just below and above of the melting layer. The results indicate many differences and similarities of the underlying process at these three different heights. The authors also investigated the instrumental effect on this analysis by comparing the results from the two different radars.
