At what height should rain gauge be set above ground?
A graduated measuring glass is used for determining the amount of precipitation. For the measurement of rainfall, the rain gauze should be placed 30 cm above the ground to prevent the splashing of rainwater.
How big should rain gauge be?
A wider diameter usually leads to more accurate readings. A 4-inch rain gauge is appropriate for most uses, while 8 inches is what the National Oceanic and Atmospheric Administration employs for its data. To avoid evaporation before the water level can be measured, UV protection is another factor to consider.
Does the size of a rain gauge matter?
Rain gauge size determines the repeatability and also the accuracy of a rain gauge. The larger the opening, the lower the statistical error in measurements in real-world applications. Always choose the largest size that your budget allows.
How deep should a rain gauge be placed under the ground?
In open areas place the gauge top approx. 2 feet off the ground. In developed areas place the gauge top approx. 5 feet off the ground.
How far should a rain gauge be from a house?
The rain gauge should be installed at a reasonable distance away from obstacles such as buildings and trees. For example, if a tree is 40ft. tall (taller than a two story house) the gauge should be placed at least 80ft.

How far does 1-inch of rain penetrate the ground?
A 1-inch water penetration should cover about 6 to 15 inches in depth on the soil. A significant change in this can be due to the soil type you use. The deeper the clay soil, it is, rather penetrate a single 1-inch rain event that happens on a loamy surface or sandy surface.
