How to Measure Rain Fall?

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 to Measure Rain Fall?

Rainfall measurement is an important part of water resource management and meteorology.

It is necessary to understand the amount of rain that falls in a given area for a variety of reasons, such as to calculate the amount of water available for agriculture, to predict flooding, and to assess the impact of global climate change.

There are a variety of methods used to measure rainfall, from manual rain gauges to more sophisticated remote sensing and radar technology. The most common method of measuring rainfall is with a manual rain gauge.

A rain gauge is a simple instrument that consists of a funnel that is placed in an open area where it can collect the rainwater. The rainwater then flows into a measuring tube, and the amount of water collected can be read on a scale.

Rain gauges can usually measure rainfall up to a depth of 25 millimetres. Rainfall can also be measured using radar technology.

A radar system transmits radio waves into the atmosphere, and these waves are reflected off of particles in the atmosphere, such as raindrops.

The radar system then measures the time it takes for the waves to return, and this can be used to calculate the amount of rainfall. Weather satellites can also be used to measure rainfall. Satellites have sensors that
