What is the resolution of tipping bucket rain gauge?

The tipping bucket rain gauge is a commonly used precipitation monitoring device, and its principle of operation is relatively straightforward. The device mainly consists of a specially designed tipping bucket and associated sensors.

The resolution of a tipping bucket rain gauge is the smallest amount of rainfall that the rain gauge can accurately measure. A tipping bucket rain gauge works by collecting rainfall into a container that flips over when it is filled with a certain amount of water. The amount of rainfall that triggers the tipping bucket is usually known and this value determines the resolution of the rain gauge.

Typically, the resolution of a standard tipping bucket rain gauge is about 0.2 millimeters (mm). This means that each dumping and emptying of the internal bucket represents 0.2 mm of rainfall. Some more advanced models may have finer resolution and are capable of measuring smaller increments of rainfall, such as 0.1 mm.

It is important to note that the actual resolution of a tipping bucket rain gauge is affected by various factors such as operator skill, quality of the gauge and environmental conditions.
