How much rain does a rain gage gage?

摘要: Abstract Rain gages of various sizes and shapes have been used for hundreds years to measure the amount rain that actually reaches ground surface. In this study, I compared rainfall data from four locations normally exposed with their orifices about 1 m (40 in.) above control installed at The caught between 5 15% less all events than did gages. For single events, where total catch exceeded 12 mm (0.5 in.), error ranged 0 75%, depending on wind characteristics during storm. Attempts develop a correction procedure based conventional measurements were unsuccessful. It was concluded most expedient way accurately in windy environments is pit gages, which eliminate effects.
