The exterior of a tipping bucket rain gauge The interior of a tipping bucket rain gauge. The tipping bucket rain gauge consists of a funnel that collects and channels the precipitation into a small seesaw-like container. After a pre-set amount of precipitation falls, the lever tips, dumping the collected water and sending an electrical signal.
Standard rain gauge. The standard way of measuring rainfall or snowfall is the standard rain gauge, which can be found in 10 cm (3.9 in) plastic and 20 cm (7.9 in) metal varieties. [83] The inner cylinder is filled by 2.5 cm (0.98 in) of rain, with overflow flowing into the outer cylinder.
The scale of dBZ values can be seen along the bottom of the image. dBZ is a logarithmic dimensionless technical unit used in radar. It is mostly used in weather radar, to compare the equivalent reflectivity factor (Z) of a remote object (in mm 6 per m 3) to the return of a droplet of rain with a diameter of 1 mm (1 mm 6 per m 3).

The term "Precipitation gauge" may refer to: Disdrometer, an instrument used to measure the drop size distribution and velocity of falling hydrometeors; Rain gauge, also known as an udometer, a pluviometer, an ombrometer or a cup is a type of instrument used by meteorologists and hydrologists to gather and measure the amount of liquid precipitation over a set period of time
Pan evaporation is a measurement that combines or integrates the effects of several climate elements: temperature, humidity, rain fall, drought dispersion, solar radiation, and wind. Evaporation is greatest on hot, windy, dry, sunny days; and is greatly reduced when clouds block the sun and when air is cool, calm, and humid. [ 1 ]
