Standard National Oceanic and Atmospheric Administration rain gauge. A rain gauge (also known as udometer, pluviometer, ombrometer, and hyetometer) is an instrument used by meteorologists and hydrologists to gather and measure the amount of liquid precipitation in a predefined area, over a set period of time.

The first devices used to measure weather phenomena were the rain gauge, the anemometer and the hygrometer. The 17th century saw the development of the barometer and the Galileo thermometer while the 18th century saw the development of the thermometer with the Fahrenheit and Celsius scales.
Cheugugi (Hangul: 측우기, Hanja: 測雨器) is the first well-known rain gauge invented and used during the Joseon dynasty of Korea. It was invented and supplied to each provincial offices during the King Sejong the Great's reign. As of 2010, only one example of the Cheugugi remains, known as the Geumyeong Cheugugi (Hangul: 금영측우기 ...
Pan evaporation is a measurement that combines or integrates the effects of several climate elements: temperature, humidity, rain fall, drought dispersion, solar radiation, and wind. Evaporation is greatest on hot, windy, dry, sunny days; and is greatly reduced when clouds block the sun and when air is cool, calm, and humid. [ 1 ]
The term "Precipitation gauge" may refer to: Disdrometer, an instrument used to measure the drop size distribution and velocity of falling hydrometeors; Rain gauge, also known as an udometer, a pluviometer, an ombrometer or a cup is a type of instrument used by meteorologists and hydrologists to gather and measure the amount of liquid precipitation over a set period of time
The snow gauge suffers from the same problem as that of the rain gauge when conditions are windy. If the wind is strong enough, then the snow may be blown across the wind gauge, and the amount of snow fallen will be under-reported. However, due to the shape and size of the funnel, this is a minor problem.
These are three different things, A rain gauge, a snow gauge and a precipitation gauge. Part of the problem with rain guage was the first sentence which said that they collected solid precipitation and I changed that. We never use the rain gauge to collect snow. We have a T200 type here as well.
The inner cylinder is filled by 2.5 cm (0.98 in) of rain, with overflow flowing into the outer cylinder. Plastic gauges have markings on the inner cylinder down to 1 ⁄ 4 mm (0.0098 in) resolution, while metal gauges require use of a stick designed with the appropriate 1 ⁄ 4 mm (0.0098 in) markings. After the inner cylinder is filled, the ...
