Keep the rain gauge twice the distance away from the height of the nearest obstruction (e.g., placing a gauge 20 feet away from 10-foot tall trees).

Place the gauge at least 2-5 feet off the ground on the side of a pole, with the top of the cylinder several inches above the top of the pole to prevent splash back.

Make sure the top of the rain gauge is level.

Keep the gauge away from sources of artificial precipitation that can affect the readings, such as sprinklers.

On the side of your gauge, you will see markings that indicate the amount of rain within. As rain falls, it will fill up the tube. What you will notice is that the surface of the rainwater appears curved, called a meniscus, which is caused by the liquid coming in contact with the sides of the tube. Read the measurement closest to the lowest point at the base of that curved surface, and you’ll have your measurement.
