How Rain Is Measured?

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.

How Rain Is Measured?

Rain is a vital part of the Earths water cycle and is an important part of the global climate system. Precipitation, which is the collective term for rain, snow, sleet, and hail, is measured in many different ways.

Rain is one of the most common forms of precipitation and is measured using a variety of instruments, including rain gauges, tipping buckets, and disdrometers. Rain gauges are the most common tools used to measure rainfall.

These instruments consist of a funnel that collects the rainwater and a measuring device, such as a graduated cylinder or a weighing scale, which measures the amount of water that has accumulated.

Tipping buckets are also used to measure rainfall. These instruments consist of a funnel that collects the water and two buckets that are connected to a pivoting arm.

As the rainwater accumulates in the funnel, it tips the arm, causing one of the buckets to tip, while the other remains empty.

The amount of rainfall is then calculated by measuring the amount of water that has tipped over into the bucket. The Disdrometer is a more advanced instrument used to measure rainfall.

It consists of an array of electronic sensors that detect the size and shape of raindrops, as
