How Do They Measure Rainfall?

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 Do They Measure Rainfall?

Measuring rainfall is an important part of weather monitoring, as it can affect a variety of things from agricultural production to flooding. Although rain is a natural phenomenon, understanding how much is falling and when is essential for proper planning and management. There are a variety of methods used to measure rainfall, including radar, rain gauges, and satellite measurements.

Rainfall can be measured by radar, which uses radio waves to detect the intensity and location of precipitation. Radar was initially used to detect incoming enemy aircraft during World War II, and today it is used to determine the location and intensity of rainfall. The radar images can be used to measure the amount of rainfall in a certain area in a given period of time.

Rain gauges are also used to measure rainfall. A rain gauge, or pluviometer, is an instrument that collects and measures the amount of liquid precipitation over a certain area. The rain gauge can measure both the rate of precipitation and the total amount over a period of time. Rain gauges are commonly used by meteorologists and farmers, as they provide a more direct measure of rainfall than radar.

Satellites are also used to measure rainfall. Satellites equipped with special sensors measure the amount of water vapor in the atmosphere
