Where do you put a rain gauge?
One of the easiest places to install a rain gauge is at the top of a fence post.
Just make sure you choose an open area, level the gauge, and ensure the top of the gauge is above the top of the fence post..
What is the most accurate rain gauge?
Stratus Precision Rain GaugeWhen it comes to the best rain gauge for you, three are superior for very different reasons. Our top choice is the Stratus Precision Rain Gauge. It is the most precise, very easy to use, exceptionally durable, and quite affordable. Meanwhile, if you’re looking for electronic versatility, we recommend the AcuRite 00899.
Is 1 inch a lot of rain?
Rainfall rate is generally described as light, moderate or heavy. … Heavy rainfall is more than 0.30 inches of rain per hour. Rainfall amount is described as the depth of water reaching the ground, typically in inches or millimeters (25 mm equals one inch). An inch of rain is exactly that, water that is one inch deep.
Why is rain gauge placed below the ground?
The purpose of the grid is to reduce wind turbulence around the gauge and rain splash into the gauge. In high rainfall and poor drainage areas some arrangement has to be made to prevent the pit from flooding during heavy rain or snow melt as this could cause damage to the electronics of the gauge.
How do I know if my rain gauge is accurate?
Tip: To have accurate results, ensure that all the water in the container is poured into the rain gauge before the test is complete. As the water flows into the rain gauge, the percentage error decreases until the measured value is the same as the expected rainfall. At that point, the error percentage is 0.00.
Is 7 inches of rain a lot?
It starts looking iffy in the 7- to 10-inch range. If it falls within a 3-day period, buildings should remain dry, but roads, swales, ditches and yards will be underwater.
What is automatic rain gauge?
Automatic rain gauges are rain gauges that electronically start working once it feels rain on the gauge. They automatically record the data, from measuring to removing the rainfall afterwards.
What is the best digital rain gauge?

How do you measure rain without a rain gauge?
Here’s what you’ll need to do:Measure the diameter of the bucket at the level of the rain. … Measure the diameter of the bucket at the bottom in the same way.Calculate the average of the two diameters.Divide by two to find the average radius.Find the average volume of rain = Depth x radius x radius x 3.14.More items…
What is the principle of rain gauge?
Weighing rain gauges operate on the principle of weighing the rainwater or snow collected by the instrument; whereas tipping bucket rain gauges measure rainfall by accumulating rain water in a bucket that tips and drains after a certain amount of rainwater has been collected.
What is the best site to close a rain gauge?
Rain gauges should also be sited relatively close to the ground but not so close that precipitation falling next to the rain detector splashes into it. The minimum guideline is no lower than two feet. However, the issue with height isn’t limited to the rain gauge being too close to the ground.
Where should a rain gauge be placed and why?
Rain gauges should be placed in an open area where there are no buildings, trees, or other obstacles to block the rain. This is also to prevent the water collected on the roofs of buildings or the leaves of trees from dripping into the rain gauge after a rain, resulting in inaccurate readings.
Is it a good idea to place a rain gauge under a tree?
It can be mounted on a fence, or placed in your yard, but the most important thing that you’ll want to remember is to not place it next to a building, trees, or shrubs. This can affect how much rainfall is in your rain gauge. … The wind can also affect it if you place it close to a house or building.
What size should a rain gauge be?
20 inchThe 20 inch gauge is the norm throughout the National Weather Service. However, other agencies like the U.S. Forest Service often use the smaller gauge. The inner measuring tube of the large NWS gauge holds 2.0 inches of precipitation.
Can you use a bucket as a rain gauge?
Rain and drizzle are the easiest forms of precipitation to measure. Rain gauges are used to measure liquid water depth and can be as simple as an open bucket with a consistent cross section throughout. Meteorologists however, use more accurate instruments and slightly more sophisticated gauges to measure rainfall.
Does it matter how wide a rain gauge is?
What is the size of a rain gauge? It doesn’t matter because it is not the volume but the height of the water we measure. … The entrance to the gauge through the funnel is narrow to avoid debris clogging the mechanism and undesirable evaporation in hot weather.
How do you make a homemade rain gauge?
Making a Rain GaugeCut the top section off a clear bottle as shown. … Place several small rocks in the bottom (for weight), then fill the bottle with water to the 0 mark. … Invert the top of the bottle into to rain gauge to act as a funnel. … Wait for the next rain and observe and record rainfall amounts.
How accurate are backyard rain gauges?
Rainwise tipping bucket rain gauges have an accuracy rating of 2% at 1.5” per hour. … The National Oceanic and Atmospheric Association (NOAA) weather observer network, uses manual rain gauges with an 8 inch diameter opening. These are considered the most accurate, but are also more expensive.
How do self emptying rain gauges work?
The most common rain detector used in electronic weather stations is the “tipping bucket” type of rain sensor. As rainfall fills the tiny bucket, it becomes overbalanced and tips down, emptying itself as the other bucket pivots into place for the next reading. …
How heavy is an inch of rain?
Volume and weight One inch of rain falling on 1 acre of ground is equal to about 27,154 gallons and weighs about 113 tons.
How do I calibrate my AcuRite rain gauge?
Place the display console close by so you can monitor it during the calibration process. Make a pinhole in the bottom of a plastic cup. Hold the cup over the rain gauge and fill it with exactly 1 cup (8 oz.) of water, allowing the water to drip into the rain gauge.
How do you use a rain gauge accurately?
To assure an accurate reading, the rain gauge should be placed in an open area away from trees, the house and other outbuildings. Position the rain gauge twice as far away as the height of a tree or other object and be sure to empty it after every rain shower.
