Other Names
Rain gauges are also known as pluviometers or udometers. These are scientific names; most people know them simply as rain gauges.
History
The first known rainfall record keepers were the ancient Greeks. Records date back to 500 B.C.
Modern Rain Gauges
The first modern rain gauge was invented in 1662 by Christopher Wren. It was a tipping-bucket style gauge.
Wind Limitations
Rain gauges do not work in hurricanes. Water cannot accumulate in the measurement tubes if the wind is too strong.
Temperature Limitations
If it is very close to freezing, precipitation can freeze on the edges of a rain gauge. This causes low measurements.
Types
There are four main types of rain gauges. These are the graduated cylinder, weight based gauges, tipping buckets and the optical gauge.
