Multiscaling analysis of high resolution space-time lidar-rainfall

In this study, we report results from scaling anal- ysis of 2.5 m spatial and 1 s temporal resolution lidar-rainfall data. The high resolution spatial and temporal data from the same observing system allows us to investigate the variabil- ity of rainfall at very small scales ranging from few meters to 1 km in space and few seconds to 30 min in time. The re- sults suggest multiscaling behaviour in the lidar-rainfall with the scaling regime extending down to the resolution of the data. The results also indicate the existence of a space-time transformation of the form t L z at very small scales, where t is the time lag, L is the spatial averaging scale and z is the dynamic scaling exponent.
