Abstract
A Monte Carlo simulation study is conducted to investigate the performance of the area-threshold method of estimating mean areal rainfall. The study uses a stochastic space-time model of rainfall as the true rainfall-field generator. Simple schemes of simulating radar observations of the simulated rainfall fields are employed. These schemes address both random and systematic components of the radar rainfall-estimation process. The results of the area-threshold method are compared to the results based on conventional averaging of radar-estimated point rainfall observations.A Monte Carlo simulation study is conducted to investigate the performance of the area-threshold method of estimating mean areal rainfall.
