The merged estimate is taken as the maximum precipitation estimate among the three sites in the overlap umbrella. WSR-88D radar sites for the period of record of the study. A storm event selected for the evaluation of the raingage networks. Results Many points emerge from this raingage network design. Figure 3 shows the differences in precipitation estimates as measured by the Binghamton versus the Albany radar.
Spatial biases are a general problem of radar-rainfall estimates.
Using a set of storm events will help reduce the problems of spatial biases. Furthermore, a merged estimate is taken to reduce these problems. Other methods may also help to reduce the effects of these biases. Errors in the estimates of precipitation from the raingage networks decrease as the density of the raingage networks increase. This is consistent with classical approaches to raingage network design.
