What is a rain gauge?
A rain gauge (also known as an udometer, pluviometer, ombrometer, and hyetometer and more) is an instrument used by meteorologists and hydrologists to gather and measure the amount of liquid precipitation over an area in a predefined area, period of time. It is used for determining the depth of precipitation (usually in mm ...
What does a rain gauge indicate?
Also, rain gauges only indicate rainfall in a localized area. For virtually any gauge, drops will stick to the sides or funnel of the collecting device, such that amounts are very slightly underestimated, and those of .01 inches or .25 mm may be recorded as a " trace ".
Why did the Tianchi basin have rain gauges?
Each of the state storehouses were equipped with a rain gauge to classify land for taxation purposes. In 1247, the Song Chinese mathematician and inventor Qin Jiushao invented Tianchi basin rain and snow gauges to reference rain, snowfall measurements, as well as other forms of meteorological data.
How does a precipitation gauge work?
A weighing-type precipitation gauge consists of a storage bin, which is weighed to record the mass. Certain models measure the mass using a pen on a rotating drum, or by using a vibrating wire attached to a data logger. The advantages of this type of gauge over tipping buckets are that it does not underestimate intense rain, and it can measure other forms of precipitation, including rain, hail and snow. These gauges are, however, more expensive and require more maintenance than tipping bucket gauges.
What is the purpose of the pluviometer?
The pluviometer of intensities (or Jardi's pluviometer) is a tool that measures the average intensity of rainfall in a certain interval of time. It was initially designed to record the rainfall regime in Catalonia, but eventually spread throughout the world.
How does a rain gauge work?
The standard United States National Weather Service rain gauge, developed at the start of the 20th century, consists of an 8-inch diameter (203 mm) funnel emptying into a graduated cylinder, 1.17 inches (29.7 mm) in diameter , which fits inside a larger container that is 8 inches in diameter and 20 inches (508 mm) tall . If the rainwater overflows the graduated inner cylinder, then the larger outer container will catch it. When measurements are taken, then the height of the water in the small graduated cylinder is measured, and the excess overflow in the large container is carefully poured into another graduated cylinder and measured to give the total rainfall. A cone meter is sometimes used to prevent leakage that can result in alteration of the data. In locations using the metric system, the cylinder is usually marked in mm and will measure up to 250 millimetres (9.8 in) of rainfall. Each horizontal line on the cylinder is 0.5 millimetres (0.02 in). In areas using Imperial units, each horizontal line represents 0.01 inch.

What is a tipping bucket rain gauge?
The distinctive feature of the tipping bucket rain gauge is its tendency to estimate the nature of the rain, that is, if the rain is light, medium, or heavy. The basic design of Tipping Bucker Rain Gauge has developed over time, like any other rain gauge, but the underlying mechanism remains the same.
How does a rain gauge work?
The rain gauge performs its function by magnifying the rain by a factor of 10. Magnification of rain helps in attaining accurate measurements.

1644 – Evangelista Torricelli (Italy): invented an instrument called the Torricelli tube, a 4 ft long glass tube containing mercury inverted into a dish, used for experiments to create a vacuum. He suggested that it was the weight of air changing from day to day that caused variation in the height of the mercury.
What is the purpose of rain gauges?
The measurement of global precipitation , both rainfall and snowfall, is critical to a wide range of users and applications. Rain gauges are indispensable in the measurement of precipitation, remaining the de facto standard for precipitation information across the Earth’s surface for hydro-meteorological purposes. However, their distribution across the globe is limited: over land their distribution and density is variable, while over oceans very few gauges exist and where measurements are made, they may not adequately reflect the rainfall amounts of the broader area. Critically, the number of gauges available, or appropriate for a particular study, varies greatly across the Earth due to temporal sampling resolutions, periods of operation, data latency and data access. Numbers of gauges range from a few thousand available in near real time, to about a hundred thousand for all ‘official’ gauges, and to possibly hundreds of thousands if all possible gauges are included. Gauges routinely used in the generation of global precipitation products cover an equivalent area of between about 250 m² and 3,000 m². For comparison, the center circle of a soccer pitch or tennis court is about 260 m². Although each gauge should represent more than just the gauge orifice, auto-correlation distances of precipitation vary greatly with regime and the integration period. Assuming each Global Precipitation Climatology Centre (GPCC) -available gauge is independent and represents a surrounding area of 5 km radius, this represents only about 1% of the Earth’s surface. The situation is further confounded for snowfall which has a greater measurement uncertainty.
How does rain affect Senegal?
Rainfall is a very important climatic phenomenon for the Sahelian economies. In Senegal, it has a very tremendous impact on agriculture and human life, which justifies the need for effective monitoring systems. In fact, the country has been experienced number of extreme events such as floods and public health problems. Despite the efforts made, it remains challenging to have real-time observations, which impact directly forecasts quality. In addition, systems used are not efficient and they are often expensive for implementation and deployment throughout the country. In this paper, we present an automatic rainfall station adapted. A prototype has been designed and implemented to ensure the reliability and availability of data in real time. In addition, a validation study is carried out in order to know its performances. For this, the designed prototype is installed on the same site near an approved industrial station, between July 1st and October 31st, 2017. The comparison between obtained results of these two stations is very satisfactory with a correlation of 99%.
