Rain gauge advisor

Rain gauges are used to measure rainfall that has fallen over a period of time. Even snowfall is usually detected when it melts. They are also known as ombrometers, pluviometers or hyetometers and belong to everyone Weather stationto. pluviometer are in meteorology additional tools in the weather forecast and are also used to calculate the statistics of rainfall in the climate. The first pluviometer were developed in 1639 and 1661 by Benedetto Castelli and Christopher Wrn. The actual development, however, took place much earlier, namely 1442 in Korea. This was the responsibility of King Sejong.

Various device types of rain knives

There are analog and digital pluviometer , Both variants can also be equipped with built-in heating, so that solid rainfall such as hail, snow and sleet can also be measured. The catching funnel of pluviometer as well as the rain drain are on some devices with temperature control and electrical heating foils provided to stay frost-free. analog pluviometer are suitable for private use at home and have above cylindrical, open vessels with a readable scale. To increase the accuracy even more, the inlet opening is often funnel-shaped, because it can catch larger amounts of rain. In addition, the influence of evaporation is reduced. In professional meteorology, the rain gauge according to Hellmann is used in the entire German-speaking area. It was invented in 1886 by the meteorologist Gustav Hellmann. This rain gauge is made of stainless steel or zinc sheet and has a sharp-edged measuring ring, which limits the collecting area. The rainwater is through a funnelinto the collection can, which is located at the bottom of the device. Therefore it is for the most part protected against evaporation. The collected rainwater is transferred to the measurement in a cylinder, which allows an exact determination of the amount. When snowfall is expected, a snow cross is placed in the upper part of the rain gauge to protect the falling snow from subsequent wind turbulence.

Rain gauge according to Hellmann and digital rain gauge

The entire Hellmann rain gauge is exchanged for a rain gauge with another perfectly identical rain gauge and placed in a cool room with the lid closed until the snow has become liquid so that it can be measured in a conventional manner. As an alternative method, a previously measured amount of water can be added to the snow, which is subtracted again after the measurement. Digital rain gauges are often equipped with a dump bucket and tipping bucket. Both systems have a shell that fills with rain. At a specified weight, the bowl tilts down and empties. Based on the number of these tipping movements, the amount of rainfall is determined. The tilting is usually detected with a magnet that sits on the tilting device and the reed contact opposite. The biggest difference between tipping bucket and tipping bucket is in the construction. The tipping bucket is more sensitive than the dumping bucket and is equipped with a two-part measuring chamber, so that no raindrops can be lost, as with the tipping bucket. The tipping spoon has the shape of a spoon and can only catch water on one side.

More information about rain gauge

The height of the collection area of ​​a rain gauge is according to the guidelines of the German Weather Service by default one meter above the ground. The height at a station height of more than 500 meters above sea level is 1.5 meters due to the expected snow fall, and even two meters at a station height of more than 800 meters above sea level. So that climatologically sensible measurements are possible, the rain gauge should be installed in a location that represents the local climate. The site must be open enough on one side to be able to safely catch even incidental rain, but on the other hand there must be protection against strong wind to reduce wind errors caused by the overflow of the collecting vessel. The rain measurement is basically very simple, but in practice it is subject to great errors again and again. As a rule, measurement uncertainties between 10 and 20 percent are generally unavoidable. Depending on the weather and the area, an interpretation of the measurement results is required.
