Rain gauges are one of the most ancient weather instruments. The ancient Greeks and people in India were the first known to keep rainfall records, about 400–500 BC. In 1441, Korea invented the first standardised rain gauge, the Cheugugi.
Who invented the rain gauge?
The first standardized rain gauge was invented in 1441 in Korea. In 1662 the first tipping bucket rain gauge was invented in Britain by Christopher Wren and Robert Hooke. The first systematic rainfall measurements were done between 1677 and 1694 by Richard Townley in Britain.
When was the water gauge invented?
Invented in 1662, this design worked by funneling the water onto a lever, that would tip once it reached a pre-set amount, and allow for an accurate calculation for the amount of precipitation.
Who is responsible for the first recorded rainfall measurements?
Not long after Galileo’s student Benedetto Custelli made the first recorded modern rain gauge measurement in 1639, Robert Hooke designed a rain gauge that is similar to what is still in use today.
How old is the rain gauge?
The rain gauge was invented in the fourth month of 1441, two hundred years before inventor Christopher Wren created a rain gauge (tipping bucket rain gauge ca. 1662) in Europe.
Is code for rain gauge?
6.5 Raingauge of appropriate capacity as specified in IS 5225 shall be used to ensure the measurement of extremes of rainfall in the event of the observer being unable to take observations repeatedly on the day of such heavy rainfall.
Why is rain gauge important?
A rain gauge is an important tool to help monitor global weather patterns, aid farmers dealing with drought and help meteorologists prepare for natural disasters.
Why is a rain gauge still used today?
Knowing the average rainfall for an area helps farmers make decisions about planting, harvesting, and irrigating crops. … Rain gauges are also used to monitor global weather patterns and help meteorologists prepare for natural disasters.
Why is rain measured in inches?
The inner tube’s diameter is just small enough to make the depth of rain ten times what it would be in a gauge without the tube and funnel. Thus, each inch in the tube is equivalent to 0.1 inches (a tenth of an inch) of rainfall. This makes it easier to read accurately!
How rainfall is calculated?
The standard instrument for the measurement of rainfall is the 203mm (8 inch) rain gauge. This is essentially a circular funnel with a diameter of 203mm which collects the rain into a graduated and calibrated cylinder. The measuring cylinder can record up to 25mm of precipitation.
Where should I put my rain gauge?
Location! Keep your rain gauge in open areas as far away from obstacles as possible, whether trees, houses, or fences. Having your gauge level is another great way to keep the readings accurate. This will help rain from splashing out and to help with winds blowing.
Which gauge gives the permanent record of rainfall?
Explanation: These are rain gauges which can give a permanent, automatic rainfall record in the form of a pen mounted on a clock driven chart. From the chart intensity or rate of rainfall in cm per hour. The recording is done by an attached siphon. 15.
What does the rain gauge measure?
A rain gauge is a meteorological instrument to measure the precipitating rain in a given amount of time per unit area. The instrument consists of a collection container which is placed in an open area.
What are the types of rain gauges?
The three major types of rain gauges are the standard gauge, tipping bucket gauge and weighing gauge.
