Variability of the Rain Drop Size Distribution : Stochastic Simulation and Application to Telecommunication Microwave Links

, 2012
Precipitation is an important component of the Earth' water cycle and needs to be carefully monitored. Its large variability over a wide range of spatial and temporal scales must be taken into account. For example, hydrological models require accurate rainfall estimates at high spatial and temporal resolutions (e.g., 1 km and 5 min or higher ...
