摘要：

In comparisons between radar and gauge measurements of rainfall, part of the scatter in the results has been attributed to the differences between the Sample volumes (representativeness errors). This report describes an experiment to measure directly representativeness errors using high spatial and temporal resolution gauge data to simulate some of the radar sampling characteristics. The results of the simulations are compared with results from real radar/gauge comparisons in the FRONTIERS radar analysis. Sampling effects are shown to make a significant contribution to both random and bias errors in these comparisons.
