FAQs

What is the short answer to rain gauge? ›

A rain gauge is a meteorological instrument to measure the precipitating rain in a given amount of time per unit area. The instrument consists of a collection container which is placed in an open area.

Raindrop works! Easy and convenient. I'm always looking for a way to get local precipitation amounts, and Raindrops is the app I turn to first. Once I identify my location, I can get total rainfall over the last 24 hours with one button push—opening the app.

Rainfall is measured using an instrument called rain gauge.

Analog Rain Gauges for a Simple Way to Measure Rainfall

Most rain gauges are just clear acrylic or glass cylinders that are usually marked in inches and centimeters or millimeters. The measuring tube is usually mounted on a fence, post, or deck rail. Sometimes it is just placed in or on the ground.

70.7 Thus the actual rainfall can be measured by the following formula h= 12.74 x V where D2 h is the rainfall measured in mm V is the volume of water collected in the bucket in ml and D is the top diameter of the bucket in cm from where rain water is collected.

As we talked about earlier for the straight-sided gauge, the number of inches of rain must be equal to the volume of water divided by the area of the collector. So, by measuring the volume and area, you can determine the number of inches of rain.

RainDrop has a free version that's really handy. But if you want a bunch of virtual rain gauges, you can get RainDrop Pro.

The Smart Rain Gauge belongs to our weather range. It works with your Weather Station to measure the rainfall at your home in real-time, giving you readings on your smartphone.

A chance of rain refers to a probability between 30% and 50%. A likely chance of rain would be between 60% and 70%. And with any probability of precipitation higher than 75%, the forecaster has the option of describing it as “periods of rain,” “occasional rain” or simply “rain,” Blier said.

One (1.00) inch of rain – A light moderate rain never reaches this amount, heavy rain for several hours (2-5 hours). There would be deep standing water for long periods of time.

How many gallons is 1 inch of rain per square foot? ›

Every square foot of roof space collects . 6 gallons of water in a 1 inch rainfall.

Rainfall rate is generally described as light, moderate or heavy. Light rainfall is considered less than 0.10 inches of rain per hour. Moderate rainfall measures 0.10 to 0.30 inches of rain per hour. Heavy rainfall is more than 0.30 inches of rain per hour.

The National Weather Service uses what is known as a 20-inch gauge, which has the capacity to collect spillover when the rain rate overwhelms the funnel. Without obstructions such as trees or buildings, the gauge can be the most accurate way of measuring rainfall.

Rain Alarm reliably warns you of rain or snow approaching your location using push notifications. Instead of predicting probabilities, we use real time data to warn you as soon as precipitation approaches you.

Rain gauge is an equipment used by meteorologists and hydrologists to gather and measure the amount of liquid precipitation (Rainfall) over a predefined area, over a period of time. There are many types of rain gauges which includes manual / ordinary type and also sensor based Automatic weather stations.

Metrologists measure the rainfall using the instrument known as 'rain gauge'. It is also known as Pluviometer, Ombrometer or Udometer.
