Abstract

The deployment of a network of rain gauges involves two stages: first, the broad distribution of gauges across a region or catchment and, second, the specific location of each gauge. The spatial distribution of gauges across a region will be determined by a combination of: (a) physical characteristics of the region, including the topography and the natural variability of precipitation, and (b) institutional factors, such as the purpose of the network (setting the accuracy and level of detail of data required as well as the resources available). The specific location of gauges will be determined by purely local factors, which would affect the accuracy of the measurements. These are primarily concerned with site exposure and wind effects that could lead to errors in catch and make the data unrepresentative of a larger area.
