In general, the measurement of rainfall by a rain gauge is expressed as the depth divided by the unit area of the total rainfall that falls on a certain area, and the millimeter [mm] is used in Korea, and the inch is used in the United States. In case of normal observation, if precipitation is less than 0.1mm, record 0.0mm, if there is no rainfall at all, fill in nothing, and the amount of snowfall is converted into 10mm (1cm) as 1mm rainfall.

Rain gauges for measuring rainfall can be roughly divided into ordinary rain gauges and automatic rain recording gauges. The rain gauge is measured by pouring rainfall collected through a funnel-shaped rain hole in a 20 cm diameter, 60 cm high cylindrical galvanized steel pipe into a rain gauge. Type standard rain gauge. Magnetic rain gauge can be divided into float type, weight measuring type, tipping bucket, optical rain gauge, etc. Especially, the rain gauge has a pair of rain gauges When the measuring cup is installed in the seesaw type and a certain amount of rainwater is filled in the measuring cup, it is inclined to one side by weight and is most frequently used for continuous rainfall measurement by measuring rainfall with an electrical pulse generated at this time.

Conductive rain gauges are widely used for automatic rainwater observation in the world because of easy digitalization of signals. There are various resolutions of conduction rain gauges of 0.1 mm class, 0.2 mm class, 0.25 mm class, 0.5 mm class, and 1 mm class. However, two types of 0.1 mm class and 0.5 mm class are used for observation stations of Korea Meteorological Agency. Rain gauge for the use of 1 mm class. In addition, depending on the size of the sorghum, it is classified into 200 mm, 225.7 mm, 447.2 mm, 8 inch, etc., and generally, a rain gauge having a diameter of 200 mm is used.

  The 0.1 mm rain gauge has a low rainfall and low rainfall intensity, which makes it possible to observe precisely up to 0.1 mm, and the 0.5 mm rain gauge has a 0.5 mm unit, which is observed in 0.1 mm to 0.4 mm, 0.6 mm to 0.9 mm, etc. Intermediate units cannot be observed, and WMO recommendations cannot be followed, but if rainfall intensity is stronger than 0.1 mm rain gauge, the error can be considered to be effective.
